Watermarking is an effective and popular technique for discouraging illegal copyright and distribution of copyrighted digital image information. One of the important features of the watermarking technique is the lossless visible watermarking, which will preserve the quality of the watermark and watermarked image. In this paper, a novel method for visible watermarking with a capability of lossless image recovery is proposed. The method is based on one to one compound mapping of image pixel values for overlaying a variety of visible watermarks of arbitrary sizes on cover images. Compound mappings are proven to be reversible, which allows for lossless recovery of original images from watermarked images. Different types of visible watermarks, including opaque monochrome and translucent full color ones are embedded as application of the proposed generic approach. A two fold monotonically increasing compound mapping is created and proved to yield more distinctive visible watermarks in the watermarked images and to be proposed deals with the combination of text, image and key watermarking. To overcome the defects in quality of image and security the new approach, a lossless visible watermarking and watermark removal for lossless image recovery is proposed.

Searching for similar sequence in large database is an important task in temporal data mining. Similarity search is concerned with efficiently locating subsequences or whole sequences in large archives of sequences. It is useful in typical data mining applications and it can be easily extended to image retrieval. In this work, time series similarity analysis that involves dimensionality reduction and clustering is adapted on digital images to find similarity between them. The dimensionality reduced time series is represented as clusters by the use of K-Means clustering and the similarity distance between two images is found by finding the distance between the signatures of their clusters. To quantify the extent of similarity between two sequences, Earth Mover’s Distance (EMD) is used. From the experiments on different sets of images, it is found that this technique is well suited for measuring the subjective similarity between two images.Keywords

A simple, rapid, economical and sensitive visible spectrophotometric method for the estimation of Meloxicam has been developed based on the formation of ion-pair of Meloxicam with dye bromocresol green in acidic medium, which was extracted into chloroform. It has absorption maxima at 415 nm. Beer’s law limit was found to be 10-50 mcg/ml. The molar absorptivity was found to be 2.17×103 (mole-1cm-1) and sandell’s sensitivity was 0.1612 (μg/cm2/0.001 absorbance unit). The correlation coefficient (r) was found to be 0.9999. The limit of detection (LOD) and limit of quantification (LOQ) was found to be 0.88 and 2.69 mcg/ml respectively of Meloxicam. The result of estimation in marketed formulations was found to be 99.86±0.32 and 97.93±0.32. The proposed method was applied successfully for the determination of Meloxicam in tablets with average recovery of 99.62±0.88 and 100.4±0.768. The method was then validated statistically as per ICH guidelines, which yielded good results concerning range, linearity, precision and accuracy.Keywords

There is a requirement for profoundly verified system and subsequently this task utilizes the verified correspondence between various hubs with the assistance of cryptographic innovation between FPGAs. This venture is huge to upgrade the security of information and code language connected for composing messages in a secret way. This proposed system focuses on the Modified Advanced Encryption Standard (MAES) to increase the speed and to reduce the hardware complexity. Advanced Encryption Standard (AES) is the most efficient public key encryption system that can be used to create faster and efficient cryptographic keys. Hypothetical examination and exploratory outcomes demonstrate that this system gives rapid just as less trades over unbound system. Standard symmetric encryption calculations give better security to the interactive media information. Be that as it may, applying symmetric key encryption calculation on progressively complex media information, may confront the issue of computational overhead. To defeat that issue, examine the AES and change it to decrease the figuring of calculation and for improving the encryption execution as far as throughput, inactivity. This change is finished by Permutation step. Altered AES calculation is a quick lightweight encryption calculation for security of information and exceedingly reasonable for the pictures and plaintext exchange than the AES calculation. With the guide of reenactment results security level and speed of the framework is expanded with equipment intricacy being decreased.

Background: The major challenge in engineering education is to educate and train the student’s community with pedagogical practices in order to determine the notable skills to solve more complex and fragile structured problems. Innovative pedagogical practices make the students to adhere to the complex formulations of the corresponding domain and its applications. The realm of good understanding of knowledge and its deliverables can be ascertained through pedagogical practices with a focus on learner-centric activities in the classroom teaching.
The actual target in teaching learning process is to make all the students to have a good exploration on the domain knowledge with success ratio. The learner success is considered to be the core metric with which we can judge the success of learner-centric activities with creativity and quality processes. Confirming the process in which the learners are engaged with the key ideas of the course to be taught makes the students to have practical implementations in Teaching-Learning process.
Objective: This research work focus on the assessment and evaluation of learner-centric techniques for outcome based education upon statistical evaluation. Students of third year (VI Semester) of two consecutive batches have been analyzed for the course on Information Retrieval (14ITPS0). Two set of batches 2015-19 and 2016-20 have been considered for the assessment and analysis of Active Learning Strategies (ALS). The incorporation has been processed using the strategic approach based on daily, weekly and monthly assessments focusing on student learning criteria and their responding behaviors for 2016-20 batch. Each paradigm has been measured corresponding to the course outcomes at each level. Significant statistical analysis has been made for validating the process behind the teaching learning process.
Real time case study: Considering the batch 2015-19 summary assignments, presentations has been used for the evaluation and assessment of interim assignments. The observed response from the students went well among the student’s community. All the students have been registered for the course and they too have completed the same. But, the time and success ratio in learning mechanism varied from student to student upon completion of the course. Considering the batch 2016-20 active learning strategies such as Quiz by Kahoot!, Flipped classroom activity and MOOCs course has been incorporated. Also, for MOOC’S online courses a set of two courses has been identified relevant to the subject of study such as Text Retrieval and Search engines & Text mining and Analytics. For the Research problem identification the students are allowed to choose the domain specific topics for the course on information retrieval. In this process the time and success ratio has also been observed it also varied from one student to another.
