Image segmentation using dynamic color gradient threshold, texture, and multimodal-merging

摘要

A method for segmenting an image receives the image. The image has a number of pixels and a number of color channels. The image is initially segmented into a number of initial regions at least by dynamically selecting a plurality of seeds within the image using a dynamic color gradient threshold and growing the initial regions from the seeds until the initial regions encompass all the pixels of the image. A texture channel of the image is generated at least by applying an entropy filter to each of a plurality of quantized colors of the image. The initial regions into which the image has been initially segmented are multimodal-merged based on the color channels and the texture channel of the image, to yield a number of merged regions corresponding to segmentation of the image.
