Side window weighted median image filtering
Webimages, an advance median filter, directional weighted median filter [14] has been proposed. This scheme uses a new impulse detection method and which is based on the differences between the test pixel and its 16 neighborhood pixels aligned with four main directions in the 5 x 5 window. WebIntegral images are a quick way to represent images for filtering. In an integral image, the value of each pixel is the summation of the pixels above and to the left of it. Apply …
