Unsupervised colour image segmentation by low-level perceptual grouping

Abstract: This paper proposes a new unsupervised approach for colour image segmentation. A hierarchy of image partitions is created on the basis of a function that merges spatially connected regions according to primary perceptual criteria. Likewise, a global function that measures the goodness of each defined partition is used to choose the best low-level perceptual grouping in the hierarchy. Contributions also include a comparative study with five unsupervised colour image segmentation techniques. These techniques hav… Show more

“…Image segmentation based on region merging is one of the oldest techniques used in computer vision [2]. Numerous existing methods which merge regions in a RGB image exploit color and edge information [3], [31], [32], [33]. For indoor scenes, the use of color is often unreliable due to numerous effects caused by spatially varying illumination [6] and the presence of shadows.…”

“…But one of the weaknesses of this method is that, it ignores the spatial relationship information of the pixels. Adolfo [4] proposed a neural network based adaptive thresholding segmentation algorithm for monochrome image.…”

“…A recent article published by Smeulders [5], reviewed more than 200 references in this ever changing field. Readers are referred to that article and some additional references [4] for more information. Most of the CBIR projects aimed at general-purpose image indexing and retrieval systems focus on searching images visually similar to the query image or a query sketch.…”
