Computer Security

Actually this is a presentation that I made for a seminar at Dinabandhu Andrews Institute of Technology and Management. Here I'm just gooing to give a preview of the content and links to it..

It starts with virus and protection from them. It also have a brief description on trijan,worm and spywares. Then it is followed by what is hacker? and their attitude, their work, the basic skills requird, different classification and how to be one. And finally how to hack, why we need to know all this, the phases involved in hacking.

Final Destination

It's been a long time that I have started this blog and haven't posted anything so let me start with documentation of my old projects that some of you may have some interest in.

Final Destination is A Computer Vision guided Robotic System that we build for competing at techfest organized by IIT-bombay (Pixel) and IIT-Kharagpur(I.M.A.G.E.).

Computer Vision and Autonomous Robot Control are active fields of research that have immense possibilities and applications in today’s world. Their successful integration into an intelligent robotic system has been a challenge that researchers have tackled using several different paradigms. We present here a wireless mobile robot design and an intelligent software system to control it. The system is primarily based on Computer Vision as its sensory input, and is capable of several navigational behaviours. The unique feature of our design is a multi-threaded approach that facilitates parallel execution of sensory processing, decision-making and robot control.
