You can use imshow() but your variable has to be of the right class.
imshow(yourImage);
yourImage should be either:
- a uint8 image with integer values in the range 0-255
- a uint16 image with integer values in the range 0-65535
- a double image with double values in the range 0-1
If you have anything else, like an RGB image with double values in the range 0-255, you'll have to cast it to one of the above types with functions like mat2gray(), rescale(), im2double(), im2uint8, etc. For examples:
rgbImage = uint8(rgbImage);
rgbImage = mat2gray(rgbImage);
rgbImage = uint8(rescale(rgbImage, 0, 255));
