Abstract: Block matching algorithm (BMA) for motion estimation is extremely normally utilized in current video coding standard like H.26x and MPEG-x as a result of its simplicity and performance and also it is a very important content in video compression the motion estimation is becoming a problem in many video applications as it to estimate the motion of the object. There are homography between 2 frames within the video sequences captured by pan-tilt (PT) cameras in their unnatural movements and therefore the geometric relationship is used to reduce the spatial redundancy in the video. In this paper, I present a homography based motion estimation algorithm and a comparative study of different algorithms. Also I introduce a unique homography-based motion for block motion estimation. This study is to provide an idea about the important tradeoff between computational complexity, result quality and various applications. This algorithm can be done on Matlab.
