Abstract

Over the last couple of decades, video processing and coding/decoding has grown exponentially. The processing
power of the computers available has grown in almost equal proportions. However, with the introduction of newer
video standards, which are further more complex, it has become imperative to work on more optimized algorithms
and implement them efficiently and judiciously. A number of parallel implementations of the algorithms have
also been introduced, including using reconfigurable systolic arrays for the same. In this paper, we compare the
two most commonly used search algorithms, Diamond Search and Three Step Search for motion estimation and
decide which one is better for a given type of video sequence. This information can help in better decision making
regarding the choice of the algorithm for a certain video sequence and save time by as much as 50%.
