This system is mainly used for security purpose in offices and industries. Nowadays in some companies anybody can enter inside the company in the name of other employee. Because the company canâ„¢t check the person photo at every time. After that person entered inside the company, if he does any unwanted activities ad the person came outside the company, nobody can find out that person. We solved this problem in our project by using RF proximity card and video camera. Whenever the person enters to the campus he has swipe the ID card. That t ....etc

This Project does the recording of vedio images form an ip camera and transfer it into a centralized computer system. The compressed video format can be stored in computer and can use for checking security issues. To start with this project you need to learn VB.net. Other languages can be used but VB.net is the easiest. Then you must get an IP camera. The camera sends images as IP packets. The camera itself will have an IP address. You can connect to that IP using TCP/IP and read images from it directly. Once you have them you can compress them ....etc

VLSI ARCHITECTURE AND FPGA PROTOTYPING OF A DIGITAL CAMERA FOR IMAGE SECURITY AND AUTHENTICATIONWATERMARKING
the process that embeds data called a watermark, a tag, or label into a multimedia object such that the watermark can be detected or extracted later to make an assertion about the object. The object may be an image, audio, video, or text .In general, any watermarking scheme (algorithm) consists of three parts, such as the following:1) Watermark;2) Encoder (insertion algorithm);3) Decoder and Comparator (verification or extraction o ....etc

Tele-Graffiti (A Camera-Projector Based RemoteSketching System with Hand-Based User Interface and Automatic Session Summarization)

Abstract


One way to build a remote sketching system is to use a video camera to image what each user draws at their site, transmit the video to the other sites, and display it there using an LCD projector. To make such a system usable, however, the users have to be able to move the paper on which they are drawing, they have to be able to interact with the system using a convenient interface, and sketching s ....etc

Our motivation came from photographs that captured a very small moment in time, such as a water droplet splattering from a faucet or a balloon during the split second that it was bursting. Human reaction, and even a camera shutter mechanisms, are too slow to reliably capture such precise moments in time. To overcome these limitations, we are deciding to employ a microcontroller hooked into various sensors and a high intensity LED array to control the shutter of the camera. Photographers interested in taking such pictures normally have to spend ....etc
