Unformatted text preview: , and then show the original image and both of the results. Comment about them. You can use load to read asc files. Other useful commands are median , conv2 3) (30 %) Load the 3x3 noise-removing blurred image derived in Prob 1). "Sharpen" this blurred image by convolving with the following Laplacian mask. Does this operation reduce the blurring ? What about the original noise? Apply a second sharpening step using this Laplacian mask. Display and submit. Would repeated sharpenings help image interpretation ? 1 1 5 1 1 4) (25 %) Write a program to sharpen 4_2.bmp using a high boost filter. You can choose the scale factor by yourself. Hint: Useful MATLAB commands: rgb2hsv , hsv2rgb , (so that only process the graylevel intensity.), and conv2 to do convolution....
