The contours of polygons generated by the image segmentation technique show jagged outlines and a large number of redundant points. Therefore, the original segmentation contours hardly conform to geographic information system (GIS) data-producing standards without generalization. With the complexity of high spatial resolution remote sensing imagery data, with variable sizes of geographic features...
To achieve a effective segmentation for liver cancer CT image, this paper utilizes comprehensive the edge detection, the watershed algorithm and region merging approach, propose a segmentation method of liver cancer CT image based on the watershed algorithm, gain a better effect in the course of liver cancer CT image segmentation, and solve effectively the over-segmentation phenomenon of the traditional...
As a requisite of the digital image process, fuzzy object extraction is of great importance. In this paper, a novel region growing method based on fuzzy connectedness is proposed. Firstly, fuzzy connectedness is taken as similarity measure between the seed pixel and current pixel and guides the region-growing process. Then, a combined stop criterion integrating adaptive threshold and usan area is...
