Barcodes create a specific pattern with the help of bars, space and square of various widths. This pattern contains the information regarding the object where it is attached. Generally, there are three different types of barcodes namely 1D, 2D and 3D. Among these types, two dimensional barcode technologies is becoming popular and useful for communication.HC2D barcode is a high capacity two dimensional, so it can hold large amount of data in small area. In existing system this HC2D barcode image recognition is implemented in mobile with android operating system. The mobile phone used here consists of a camera, supporting application and display device. Then the source image is captured by the embedded camera device in mobile phone. But, in the existing method the obtained average recognition rate is 91.33%. In this technique the recognition rate is improved by adding a Wiener filter in Barcode Recognition Algorithm. Here, the noise is reduced with the help of this filter. This leads to increase the recognition rate up to 93%.

One of the foremost problems that governments or huge companies have to be compelled to deal with is Vehicle Tracking. This paper describes a practical model for routing and tracking of mobile vehicles in a large area environment using the Global positioning system(GPS) and Global system for mobile communication(GSM). The GPS attached to the vehicle will continuously move along with it and it will subsequently calculate the coordinates of each position it covers. It will also communicate the location with the help of GSM modem, which is installed in both the transmitter and receiver section, when the user requires the position. The main focus of the paper is on explaining the intercommunication of various technologies in a real-time system. The model includes a GPS for gathering the position of the user, GPRS for transferring positions data to the central server and the demonstration of the collection of this data. It further discusses the protocols and approaches that enable the functioning of the system, along with the economic side of the system.Keywords
