BMA Performance of Video Coding for Motion Estimation

The major advantages of Block Matching Algorithm is it can reduce the temporal redundancy by placing a direction and magnitude of a Motion Vector (MV) instead of an image block. There are various type of BMA for motion estimation technique have been proposed to enhance the accuracy of the MV of the image block and also to reduce the computational complexity of the BMA for time consuming. This paper investigate and presents a very brief introduction to seven type of famous BMA that are Exhaustive Search, Three Step Search, New Three Step Search, Simple and Efficient Three Step Search, Four Step Search, Diamond Search and Adaptive Rood Pattern Search. This paper also performs all of the seven BMA techniques with different parameter of I and P mode sequence, different search range and also different block size.
