摘要
A method and apparatus for single channel color image segmentation using local context based adaptive weighting is provided. The varying weightings of the projection vector are determined as a function of local input image activity context. A Sobel operator is used to calculate the input image activity. A binary map is created for each color channel and is adapted to store binary markers indicative of local activity levels on a per pixel basis. The binary maps are low pass filtered and then normalized to generate a context based adaptive weighting vector for use in single color segmentation of a multi-channel color image signal.
