METHODS AND SYSTEMS OF PERFORMING ADAPTIVE MORPHOLOGY OPERATIONS IN VIDEO ANALYTICS
First Claim
1. A method of performing content-adaptive morphology operations, the method comprising:
- performing a first erosion function on a foreground mask of a frame, the first erosion function setting one or more foreground pixels of the foreground mask to one or more background pixels;
determining a complexity of the foreground mask; and
determining whether to perform one or more additional erosion functions for the frame based on the determined complexity of the foreground mask.

Abstract
Techniques and systems are provided for processing video data. For example, techniques and systems are provided for performing content-adaptive morphology operations. A first erosion function can be performed on a foreground mask of a video frame, including setting one or more foreground pixels of the frame to one or more background pixels. A temporary foreground mask can be generated based on the first erosion function being performed on the foreground mask. One or more connected components can be generated for the frame by performing connected component analysis to connect one or more neighboring foreground pixels. A complexity of the frame (or of the foreground mask of the frame) can be determined by comparing a number of the one or more connected components to a threshold number. A second erosion function can be performed on the temporary foreground mask when the number of the one or more connected components is higher than the threshold number. The one or more connected components can be output for blob processing when the number of the one or more connected components is lower than the threshold number.
