convert image and linear stretch
显示 更早的评论
If i have an array of type double, how can i convert it to uint8 and linearly stretch all the values such that min = 0 and max = 255 ? do I have too write my own code for this ? Would this be the correct code ?
K = (depth - min(depth(:)))/(max(depth(:)) - min(depth(:)))*255;
