WebFeb 11, 2016 · Interactive Tutorials Median Filters for Digital Images. The median filter is an algorithm that is useful for the removal of impulse noise (also known as binary noise), which is manifested in a digital image by corruption of the captured image with bright and dark pixels that appear randomly throughout the spatial distribution.Impulse noise arises … WebImage pre-processing. For this study, the noisy input images were obtained using contrast enhanced crack images and a Laplacian filter, as described in Section 4.1. However, the method will work with any binary crack image. The input image is loaded in uint8 format with pixels P(x,y) of values 0 and 255.
WebWe first create a binary mask from a specified ROI, which returns a matrix containing only 1 or 0. To return the selected portion of the image, we perform a logical AND of the binary mask matrix with the image using logical indexing. The resulting image will contain the extracted portion.
