Image segmentation apparatus, an image segmentation method

The image segmentation apparatus and image segmentation. The image segmentation apparatus comprising: image feature extraction unit extracts features of an input image in each image block of an image, each image block comprising one or more pixels; evaluation unit, based on the image feature of each image block is evaluated on the space neighboring two or more adjacent image blocks are clustered into the same cluster confidence; and a clustering unit clustering the image block based on the sample, taking into account the evaluation unit in the clustering process the evaluation results, each cluster forming a divided image block area of ​​the input image, wherein the evaluation unit comprises: an edge map extraction module extracting the edge on the input image to obtain edge image; edge loss calculating module calculates an edge in FIG. edge loss between the adjacent edges of the adjacent tile image corresponding to the block; and a confidence calculation module, based on the edge image blocks adjacent to assess damage is clustered into the same cluster confidence.
