This paper presents a new method for segmentation of images into regions and for boundary extraction that reflect objects present in the image scene. The unified framework for image processing uses a grid structure defined on the set of pixels from an image. We propose a segmentation algorithm based on hypergraph structure which produces a maximum spanning tree of a visual hypergraph constructed on the grid structure, and we consider the HCL (Hue-Chroma-Luminance) color space representation. Our technique has a time complexity lower than the methods from the specialized literature, and the experimental results on the
Berkeley
color image database show that the performance of the method is robust.
