Abstract

Augmented reality is a new technology which is capable of presenting possibilities that are difficult for other technologies to offer and meet. AR will really alter the way individuals view the world. Augmented reality X-Ray Vision is an emerging concept. While AR deals with virtual and real objects coexisting in the same space, AR X-Ray Vision is a subdivision of the broad spectrum of AR, which provides a "see through" vision among real world objects. In this paper, we have thoroughly analysed the existing methodologies dealing with AR X-Ray Vision and we have come up with a convenient method that enables easy implementation.

This paper deals with creating a methodology to provide an X-Ray vision using the anaglyph technique and finally integrating it with the Leap Motion Controller to enable gesture interaction to move the window around through which the point of interest can be viewed. The limitations of the suggested methodology have also been discussed. This system enables the user to perceive depth between two regions with the help of just anaglyph glasses without the use of any head mounted display devices.

Can be extended to that of medical field, where X-Ray vision is of increasing importance to view the layers of skin and bones of a patient giving the doctors and surgeons an approximate depth perception.

Abstract

Objective: This research aims at formulating a method to categorise a given class of objects by obtaining a weighted matrix computed as explained below. Methods/Analysis: The method deployed can be branched into two phases: Training and Testing. In the first phase, a set of images of the concerned objects are taken. By set of images, one can refer to images of different objects, or different positions of the same object. The features are then, extracted for these input images and stored in the database as vectors. Any computation hence forth, is performed using these vectors. In testing stage, the algorithm uses its knowledge to identify the input image to a specified class. Findings: Our method is computationally inexpensive since all the calculations are performed on the basic grounds of matrix operations. This method is not just limited to the domain of object recognition alone. Any real-time entity that can be statistically represented in a vector form can be deployed. All that is required of the application is that the range of vectors is defined so as to obtain the minimum components and maximum components, individually. Once this is obtained, the algorithm will be sufficient to identify any input and will accordingly determine the category to which it belongs. The only challenge identified is that the range of vectors obtained from the input data for various categories must not overlap. That being the case will result in multiple hits or in simpler words, will give an incorrect result. Further work can be implemented on how to make the algorithm independent of this dependency. Also, the algorithm improves the results through various illumination and scaling conditions and this has been discussed in results and analysis section.Even with the existing methods to recognize an object, this algorithm can be combined to categorize or classify objects. Conclusion/Application: The proposed algorithm successfully classifies the input image into one of the trained categories by identifying the features followed by computing these obtained features as prescribed the given algorithm.

Abstract

Background/Objective: The Indian automobile market has seen a drastic change in its trends over the past decade with several road commuters opting for mid-range sedans and SUVs, owing to the safety features of cars that two-wheelers can never provide. At times, the driver is not fully aware of his surroundings, leading to inconveniences and compromises on safety. Methods/Statistical Analysis: This problem has several facets to it. Blocked vision due to a large vehicle in front is a major hassle that persists especially during heavy traffic, in turnings and in narrow lanes. Bright headlights at night cause discomfort and troubled vision to drivers. It is the worst nightmare of a “fuel-conscious” driver to get caught in a traffic jam when he could have chosen a different lane and or to be forced to return back due to blocked roads. The most frustrating experience for any driver would be to get stuck under the sweltering sun in a road either due to a flat tire or an empty fuel tank. Result/Findings: These issues could be solved if the driver is given constant inputs about vehicles near him and the fuel level, battery conditions and tire pressure status. Providing information from other vehicles could be facilitated through vehicle-to-vehicle communication. Conclusion/Application: These applications can be incorporated into the future self-driving cars. This application also increases the safety of the drivers thereby decreasing the road accidents.

Abstract

Background/Objectives: This paper focus on the necessity of intelligent traffic system and the peculiar way of implementation with embedded system tools. Here it is implemented using an object counting methods and detection of emergency vehicles simultaneously thereby control the traffic signals based on the priority outcome. Methods/Statistical analysis: Presently various system do provide a cost effective solution, but the rate of successful operation is bad. Inductive loop detectors installed under surface, this fails in case of poor road condition and so. In the other system, the density is found by installing IR detectors along the side of the lane. These systems operate less efficiently where they are not applicable in the real time process. This method uses image acquisition method using a real time live video stream and the algorithm is processed using MATLAB. Results/Findings: The results obtained with the prototype are much encouraging and the system does help the present traffic control system to be more efficient. Conclusion/Application: Computer Vision being one of the most researched are for the future technologies, this system will add gain to this sector with efficient operation replacing the current primitive timer traffic control system. This helps the emergency casualties to be attended quickly without panic of traffic congestion.

Abstract

The paper mainly aims at optimizing, restoring and reconfiguring the faulty area in a distribution network by locating and isolating the faulty block. Restoration involves changing the switch status to maximize the supply to loads that are left unsupplied after fault removal, after that system optimization is done using reconfiguration. In the proposed system restoration and reconfiguration process is achieved in 16 bus system and simultaneously load flow analysis is performed before and after the fault and the same is verified in MATLAB. Optimization using BPSO is done in order to get the most stable configuration for restoration process by minimizing the LBI (load balancing index). FPGA is used to generate the pulses in order to control the switch status and finally the results are verified and compared with the FPGA hardware kit.

Abstract

Embedded Systems are playing a vital role in all the fields. Everything is embedded system in the modern world now a days right from the AC to Pacemaker including so many other applications as well. So we thought of making use of embedded system in the field of Medicine. And most importantly our eyes! We are trying to deploy microcontroller for intraocular pressure monitoring as glaucoma is the origin of blindness, in which the optic nerve is damaged, leading to advance and permanent loss of vision. It is found that raised intraocular pressure is a major risk factor for developing glaucoma (above 22mmHg or 2.9Kpa). In fact 6 million individuals are blind in both eyes from this disease. Often glaucoma has no symptoms, which can suddenly result in vision loss and it requires early detection, regular eye exams and treatment to prevent the eye sight. A number of medications are currently in use to treat glaucoma and we have given the complete set up details and implementation ideas as well along with clear analysis of results for detecting intraocular pressure in the eye in order to prevent glaucoma. Many researches are going out to find the cause for increasing the fluid pressure in the human eye and to improve its diagnosis and treatment.

Abstract

Improper tire pressure is a safety issue that is often overlooked or ignored. A drop in tire pressure by just a few pounds per square inch (PSI) can result in the reduction of gas mileage, tire life, safety, and vehicle performance. To address this problem, an automated system that will alleviate the need for actively monitoring tire pressure was designed. This report documents the design process for an onboard tire pressure monitoring system (TPMS) consisting of transmitter in each tire and a central receiver. The Pressure data is transferred to the central receiver through wireless transmission. The system takes periodic tire pressure readings and warns the driver at abnormal pressure readings. TPMS comes with several pre-defined tire pressure settings and allows the user to enter their own pressure setting if needed. Pressure settings, current pressures and flat/leak notifications are all displayed on a liquid crystal display (LCD) located in the dash. This system will take the maintenance out of upholding tire pressure and increase tire life, fuel efficiency and vehicle safety and performance. The system development process constitutes of defining the product requirements, Transmitter sensor selection, PCB design, circuit verification, and software development, testing and integrated testing.

Abstract

Background/Objectives: Providing security to systems is one of the major challenges faced in day-to-day life. Biometrics plays a vital role in ensuring security. Out of the different existing recognition systems available - namely face, finger, gait, retina and so on, sclera recognition system gives out better performance. Sclera is the white part of the eye, which is unique and consistent in nature because of which it is chosen for recognition. In this paper, we analyzed the existing sclera recognition system with both human and animal eye images. Methods/Statistical Analysis: In this paper, we compared the performance of the algorithm with both human and animal eye images. The animals we considered for the algorithm analysis include deer, buffalo and lion. Human eyes are the most observable due to the presence of more sclera area. The blood vessel patterns present in the sclera region are stable over lifetime and unique person by person, thus making it appropriate for identification. The results show that the algorithm works better for human eye. Results/Findings: In this paper, we compared the extracted input vessel structure with that in the database and verify whether the input is authorized or not. It is observed that the system underperforms for animal eye images, whereas it shows an acceptable performance with human eye images. Conclusion/Application: The results prove that the algorithm works satisfactorily for identifying human. It can be incorporated with other recognition systems to build up a multimodal biometric system that can provide better security than the existing systems.

Abstract

Background/Objectives: To ensure pedestrian safety in highways predominantly at night. Application: By introducing piezoelectric sensors embedded on highways, which automates the notification lamps that help both pedestrian and drivers to know each other’s presence. Methods/Statistical Analysis: The basic method we implement is getting the feed of digital HIGH and digital LOW from the piezoelectric crystals. The state of the pedestrian cross decides the output signal of the notification lamp. This helps the fast drivers on the highway to adjust their acceleration with prior alert of movement on the road. The prototype result with few minutes delay of glowing, the notification lamp can be set in real time with little more depending on the length of the cross. Findings: The night time travelers on the highway have the difficulty of vision due to optical problems of the front vehicle glass. The irritation due to high beam of the opposite vehicles distract the proper vision of the road. The pedestrians from local area are becoming a casualty of this situation. And the speed at which the drivers come is not possible to reduce in small period of time. Prior alert is required for this.

Abstract

Objective: The idea is to upload files into cloud using gestures. A “Gesture” is a form of movement of part of a body, especially the hand or the head, to express an action. Waving of the hand over the phone is used as a gesture to export files into the cloud. Methods/Analysis: The type of the file to be uploaded into the cloud can be either a picture or a video. This is accomplished using an application similar to gallery. To perform the task, the application is invoked to view a picture or video, when the hand is waved over the phone. The gesture is recognized and the currently viewed file is uploaded into the cloud. The cloud service used here for uploading is Dropbox. The size of the media files is generally large and uploading it will take time, so the size is reduced through a compression algorithm. There is a buffer which tracks the uploading part and will see to that, that the entire media file is uploaded into the cloud. Findings: Through this application the file can be uploaded into the cloud through a gesture easily and effectively. Also, it is found that the application developed is found to be stable in tough testing conditions. Application/Improvements: This app reduces the human effort to a large scale and most importantly it does not occupy more space in the handheld device.The same app can be further ported to IOS for apple phones and IPads.
