Splits a motion history image into a few parts corresponding to separate independent motions (for example, left hand, right hand)

[segmask, boundingRects] = cv.segmentMotion(mhi, timestamp, segThresh)

Input

• mhi Motion history image.
• timestamp Current time in milliseconds or other units.
• segThresh Segmentation threshold that is recommended to be equal to the interval between motion history "steps" or greater.

Output

• segmask Image where the found mask should be stored, single-channel, 32-bit floating-point.
• boundingRects Vector containing ROIs of motion connected components.

The function finds all of the motion segments and marks them in segmask with individual values (1,2,...). It also computes a vector with ROIs of motion connected components. After that the motion direction for every component can be calculated with cv.calcGlobalOrientation using the extracted mask of the particular component.
