Edge DetectionImage SegmentationEdge detection is the first step in image segmentation. Image Segmentation is the process of partitioning a digital image into multiple regions or sets of pixels. Edge detection is one of the most frequently used techniques in digital image processing. The goal of ...
Edge Detection with MATLAB Edge detection is a common image processing technique, and can be used for a variety of applications such as image segmentation, object detection, and Hough line detection. Use edge detection effectively by using the 'edge' function in MATLAB®, and also explore the...

When I perform edge detection (canny) on this segmented image, a lot of unwanted edges are not present because they have been merged away: http://imageshack.us/photo/my-images/69/edgek.png/ However, there are still many more edges than those that I am interested in. Does anyone know ...

BW = edge(I,method) detects edges in image I using the edge-detection algorithm specified by method. example BW = edge(I,method,threshold) returns all edges that are stronger than threshold. BW = edge(I,method,threshold,direction) specifies the orientation of edges to detect. The Sobel and...
