Sobel Edge Detection Filter

This filter is implemented using the itkSobelEdgeDetectionImageFilter in ITK. This filter computes the gradient of the image using the Sobel operator and find the magnitude of the gradient vector. The magnitude is computed using the sum of the squares of the components of the gradient. Fig. 1 shows the result obtained by applying the sobel edge detection filter on the input image seg_orig.tif.

Parameters:

  • 1. NumberOfThreads - this parameter gives the number of threads that the execution phase of the algorithm should be split into.
