[0041] In order to understand the content of the present invention more clearly, it will be described in detail with reference to the drawings and embodiments.
[0042] A kind of page salient element extraction algorithm and system based on the weighted hypergraph model proposed by the present invention comprises the following steps:
[0043] Step 1: Segment the input image into superpixels using a simple linear iterative clustering algorithm;
[0044] In the human visual system, information is usually processed with semantic information. Superpixel segmentation in computer vision imitates the preprocessing stage in the human visual system. When the human visual system processes information, it forms small areas with similar color and texture features and adjacent pixels in the image for overall processing. These small areas called superpixels. Among many superpixel segmentation algorithms, compared with other superpixel segmentation algorithms, the simple linear iterative c...
