The SAD value is used to calculate two different thresholds that can categorize the motion of a current block into slow, medium or fast
motion block. According to the selected category, a suitable search window size can be estimated.

motion block sizes," in Proceedings of the International Conference on Image Processing, 2003, Vol.3, pp.
If the search path was always directed in the constant direction, the
motion block matching would be easily gotten into local minimum.
While different settings in the control system might be programmed depending on the part, a typical casting might use a closed loop
motion block to slow the shot cylinder as the die is nearly full.
The robot also moves backward or forward within a
motion block to simplify the teaching and operating functions.
Part of the motion detection algorithm is about finding the maximum sub-matrices which accumulates smaller
motion blocks into a larger one.
The
motion blocks controlled the Sprite's movement and led players on a quest to four stages of the map, across the fictitious land of Deltora.
The PacDrive 3 updates I/O
motion blocks at one millisecond each, giving Lanzara outstanding motion control and overall flexibility, the company says.
Improvements in cycle time are possible with the control planning the acceleration profile over many
motion blocks instead of dealing with individual blocks.
In the Kalman filtering,
motion blocks have quite weak filtering strength to keep their motion characteristic, while still blocks have strong filtering strength to reduce the noise.
