Home: Color: Lena sRGB


The above image is in the sRGB color space.  Depending upon your output device, you may need to perform a transformation on the image.  The transformation would be from sRGB to a device independent color space such as CIELAB and then from the device independent color space to the device dependent values of your output device that produce those CIELAB values (if your device can create those values -- see Color Device Gamut ).

Once you have properly displayed the image, Image (a) is the commonly used Lena image as it often appears in image processing journals (as a color image).  Image (b) is from my desktop scan of an originally published Lena image.  Image (c) is the corrected version of image (b), creating a close approximation to the originally published Lena image.
