WitrynaDescription. J = imclose (I,SE) performs morphological closing on the grayscale or binary image I, using the structuring element SE . The morphological close operation is a dilation followed by an erosion, using the same structuring element for both operations. J = imclose (I,nhood) closes the image I, where nhood is a matrix of 0 s and 1 s ... WitrynaEstimate the gradient threshold and number of iterations needed to perform anisotropic diffusion filtering of the image. Filter the noisy image by using anisotropic diffusion …
