Pixels within the same segments share certain characteristics. Therefore, in this paper, we simplify the segmentation task to a superpixel-merging decision problem by considering discriminative features. Characteristics, including border, color, brightness, area size, sharpness, saliency, texton, and etc. are taken into account. We propose a multi-stage superpixel-clustering algorithm to merge superpixels of similar characteristics. In the first stage, the fully convolutional network is applied to decide whether the boundary of two adjacent superpixels should be kept or not. The model is trained basing on color, superpixel boundary, and edge detection result of the image. In the second stage, scoring method and SVM classification model are used to further decide whether the rest superpixels should be merged or not. We consider up to 14 factors to further improve the performance. Overall, simulations and evaluation metrics show that our algorithm has highly accurate segmentation results. |
