  • FAST IMAGE SEGMENTATION USING REGION MERGING WITH A K-NEAREST NEIGHBOR GRAPH
    Publication number: 20110075927
    Abstract: The present invention has disclosed a process of image segmentation, which comprises applying edge detection to an image to obtain an edge image and preprocessing the image; oversegmentating the preprocessed image to obtain the plurality of initial partitions; constructing k-NN Graph for the oversegmented image based on the similarity between the initial partitions; and using k-NN Graph to merge the initial partitions. With the present invention, the merging process can be accelerated and the segmentation accuracy can be improved.
