So, we first use the canny algorithm to convert the image into a binary image and get the image contour.
The initial boundary points were estimated using the Canny edge algorithm, and the result image was shown in Figure 4(b).
Similarly, the E d g v) symbol represents the values from the edge detector, which are defined using the Canny Edge Detector algorithm [27] over the input images.
(4) Using the Canny operator to delineate landslide boundaries based on the classification results of PLS and PNLS, we obtained results consistent with the referenced landslide inventory maps.
In this paper, vegetation patches are detected using the canny edge detector and ellipticity measurement based on ALOS fusion image, and the whole processing steps were given.
Boundary tracking using the Canny approach took an average of 19 seconds per volume.
For each nucleus, the background signal was first reduced by a Tophat transformation, following which the edges were detected using the Canny method.
In order to compute the feature, first an edge map is computed using the Canny-Edge detector.
We use the Canny edge detection algorithm to find edges.
In the Canny algorithm, an image is smoothed using a Gaussian filter with a specified standard deviation,, to reduce noise.
