A fuzzy measure for objective evaluation of interactive image segmentation algorithms

Image segmentation is an important research area in computer vision and many image segmentation methods have been proposed, therefore it is necessary to be able to evaluate the performance of image segmentation algorithms objectively. For natural images, usually we use interactive image segmentation to provide a means of accurately extracting semantic objects from an image efficiently. In interactive segmentation the users only need to roughly indicate the location and region of the object and background by using markers. In this paper we present a new fuzzy metric to evaluate the accuracy of interactive segmentation algorithms, based on correlation of pixels. Also this measure is based on segment-by-segment comparisons of a segmented image and a ground-truth and is sensitive to the position of each object. Experimental results were obtained for a selection of test images and show that it´s a proper measure for comparing interactive image segmentation algorithms.
