PURPOSE: To extract the exact contour of an object without being affected by noise even in an image where much noise exists and locally large noise coexists in particular, in a contour extracting method minimizing the sum total of elastic energy that plural discrete points have, image energy ...
Contourfilling is one of the most important problems in image and graphics processing. 填充是计算机图形处理领域的基本算法. 期刊摘选 It clings to the hill tightly, following everycontour. 它紧紧依附在坡路上,紧随每一段轮廓线. 期刊摘选 The cursor or acontourline the graphics object must be in th...
1. A pattern model creating method in image processing for positioning by searching an object to be searched that is similar to a pre-registered image out of an image to be searched by use of a pattern model corresponding to the registered image, the method including the steps of: extracting...
ues. In case of a contour array (tuple), you must loop over all the contours and select each one using select_obj. To convert contours to regions, simply call the operator gen_region_contour_xld. The operator paint_xld paints the contour with anti-aliasing into an image. The operators f...

Active Contour Model, also known as snakes, is a technique used in image processing for contour detection and image segmentation. The method involves defining an initial contour near the object of interest in the image and then iteratively deforming the contour to minimize an energy function that ...
