Abstract: Techniques of compressing color video images include computing a delta quantization parameter (ΔQP) for the color images based on a similarity between the depth image surface normal and the view direction associated with a color image. For example, upon receiving a frame having an image with multiple color and depth images, a computer finds a depth image that is closest in orientation to a color image. For each pixel of that depth image, the computer generates a blend weight based on an orientation of a normal to a position of the depth image and the viewpoints from which the plurality of color images were captured. The computer then generates a value of ΔQP based on the blend weight and determines a macroblock of color image corresponding to the position, the macroblock being associated with the value of ΔQP for the pixel.
