Matlab figure flashes back and forth between black&white and color

问题

I'm trying to display a color disparity map, but it first displays black and white until I do 'colormap jet' then it's in color.

How can black and white image be suppressed?

            imshow(disparityMap, DisparityRange ); 
            title('DISPARITY MAP');
            colormap jet;

回答1:

Specify the colormap parameter to imshow.

imshow(disparityMap, DisparityRange, 'colormap', jet);

Example use

im = imread('cameraman.tif');
imshow(im, [60,200], 'colormap', hsv);

We get this image:
