Morphological processing of videostream frames binary masks

One of the primary tasks of videoframes processing of digital videostreams is to quantify the geometric structure of moving objects, in order to extract information from videostreams frames. In this paper we purpose a recursive algorithms that are based on morphological conditional dilation and conditional erosion operations. Practical implementation of purposed algorithms on real-time video sequences shows, that computational complexity of purposed algorithms is equal to m+1, where m - number of pixels in kernel.
