Image processing system with automatic segmentation and method of operation thereof

摘要

An image processing system and method of operation includes: a source image having source pixels; a homogeneity image module for forming a homogeneity image having homogeneity pixels each with a homogeneity value indicating the local homogeneity of source pixels of the source image; a watershed image module, coupled to the homogeneity image module, for forming a watershed image having watershed segments with a segment weight, the watershed image formed by segmenting the homogeneity image, and for merging one of the watershed segments with another of the watershed segments both having the segment weight less than or equal to a segment threshold; a contour map module, coupled to the watershed image module, for forming a segmentation contour map having boundaries of the watershed segments formed by merging the watershed segments; and a composite image module for forming a composite image with the segmentation contour map for display on a device.

1. A method of operation of an image processing system comprising:
receiving a source image having source pixels; forming a homogeneity image having homogeneity pixels each with a homogeneity value indicating the local homogeneity of source pixels of the source image; forming a watershed image by segmenting the homogeneity image, the watershed image having watershed segments with a segment weight; merging one of the watershed segments with another of the watershed segments with both of the watershed segments having the segment weight less than or equal to a segment threshold; forming a segmentation contour map having the boundaries of the watershed segments formed by merging the watershed segments; and forming a composite image with the segmentation contour map overlaying the source image for display on a device.
