Matlab – Laplacian Mask

Another part of Digital Image Processing is the Laplacian mask. Laplacian mask contains the coefficients of the Laplacian operator (second order derivatives). When dealing with Laplacian mask,you must be very careful with the difference in sign when combining either by adding or subtract a Laplacian filtered image with another image. Laplacian operator have some effect. It tends to produce image that have grayish edge lines and other discontinuities in brighter intensities, all superimposed on a dark, featureless background. To correct the problem of featureless background, you must add the original and Laplacian filtered image together. Continue reading “Matlab – Laplacian Mask”
