What are the type of block matching algorithms?

Two different types of fixed patterns are used for search, Large Diamond Search Pattern (LDSP) Small Diamond Search Pattern (SDSP)

What is block based motion estimation?

The block-based motion estimation algorithm is mainly aimed to estimate the motion (motion vector) between macro block of current frame and perfectly matched candidate block of reference frame. The simple matching criterion is sum of absolute difference (SAD).

What is motion estimation used for?

Optical-flow or motion-estimation algorithms can be used to detect and delineate independently moving objects, even in the presence of camera motion. Of course, optical-flow-based techniques are computationally complex, and hence require fast hardware and software solutions to implement.

What is full search algorithm?

One of the first algorithms to be used for block based motion compensation is what is called the Full Search or the Exhaustive Search. In this, each block within a given search window is compared to the current block and the best match is obtained (based on one of the comparison criterion).

What is mesh based motion estimation?

The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the convent…

What is motion compensation system?

Motion compensation system equipment includes a variety of products designed to compensate for the vertical movement of offshore drilling rigs due to heave.

What is the use of linear search algorithm?

In computer science, a linear search or sequential search is a method for finding an element within a list. It sequentially checks each element of the list until a match is found or the whole list has been searched.
