ABSTRACT
Segmentation of video object extraction is the bases of video analysis, video object segmentation generally use two algorithms:
2.1 Edge detection
Some algorithm for video object segmentation using edge detection methods, namely the operator in the candidate region to extract edge pixels to get the target contour. Commonly used edge detection is the use of operator images calculus. Operator can be viewed as an array, its essence is to act as a fixed size, by numerical convolution of the nuclear operator’s reference point is usually located in the center of the array. Nonzero part of the array size is known as the nuclear support.
