Design & Implementation of Motion Detection & Reconstruction of Image Using Modified Pixel Motion Approach

The human perception has the capability to acquire, integrate, arid interpret all this abundant visual information around us. It is challenging to impart such capabilities to a machine in order to interpret the visual information embedded in still images, graphics, and video or moving images in our sensory world. Disparate as they may seem, these many applications share one common thread in all such applications, the demand is high for accurate estimates of motion requiring minimal computational cost. In this, a new technique called estimating the difference between two frames of image using Pixel motion estimation technique is proposed. The proposed technique attempts to decreasethe computation time between the current frame and the next frame.The displacement of each picture element in each frame forms the displacement vector field (DVF) and its estimation can be done using at least two successive frames. The pixel based approaches depend upon intensity of image and its performance is affected by presence of noise. In this, it also proposes real time motion estimation and enhancement based difference of frames. The PSNR and MSE are also calculated. All simulations are done in MATLAB 8.1.
