Witryna29 cze 2024 · uint8 type u = imread ('parrot.bmp'); gives a matrix a type uint8. uint8 type = integers between 0 and 255. This is the 8-bits representation for pixel gray-level, but it is not possible to do computation with this : x = uint8 (250); y = uint8 (30); s = y+x d = y-x m1 = (y+x)/2 m2 = y/2 + x/2 WitrynaThe im2uint8 function assumes that your double image is scaled to the range [0,1].If your image has values larger than 1 or smaller than 0, these values will be clipped.See the …
