WebJan 25, 2024 · The Canny edge detector is an edge detection operator that uses a multi-stage algorithm to detect a wide range of edges in images. ... The equation for a Gaussian filter kernel of size (2k+1)×(2k+1) is given … Web3. Median Filtering¶. Here, the function cv2.medianBlur() computes the median of all the pixels under the kernel window and the central pixel is replaced with this median value. This is highly effective in removing salt-and-pepper noise. One interesting thing to note is that, in the Gaussian and box filters, the filtered value for the central element can be a value …
