Abstract
A method, apparatus and computer program product are provided to process a compressed image, such as a normalized DICOM image. A method may receive a compressed image having pixels that each have by a pixel value having a predefined number of bits in a grayscale format. The method may decompress the image by mapping the pixel value into two channels of a multi-channel output buffer, such as a red-green-blue (RGB) output buffer, such that each channel has fewer than the predefined number of bits. The method may render a scene of the image based upon camera coordinates and, for a rendered pixel, sample a plurality of RGB values, convert the plurality of RGB values to the grayscale format having the predefined number of bits, perform an interpolation of the RGB values following conversion to the grayscale format and perform a window level operation on the result of the interpolation.
