7. Consider a 2x2 color image (i.e., 4 pixels). The 8-bit (R,G,B} values of the pixels are shown in the following table. R G B Hue? Pixel-1 160 240 160 PR= Pixel-2 110 110 220 (a) What would be the expected hue values of the pixels? (b) Calculate the relative % of energy represented by the {R,G,B} components. For example, you can use the following equation to calculate the % for the R component. R (n) n=0 [R(n)+G(n) + B (n)] n-0 Pixel-3 220 220 0 Pixel-4 240 240 240 (c) Calculate the {Y,1,Q) values for each pixel using the transformation matrix discussed in the class. (d) Calculate the relative % of energy represented by the {Y,1,Q) components. Compare these values with those obtained in part (c). 8. Calculate the YCbCr values of the 4 pixels considered in Problem 7. Comment on the Y, Cb, Cr values. 7. Consider a 2x2 color image (i.e., 4 pixels).

To answer these questions we will have to process each part step by step a Expected hue values of the pixels Hue is defined as the degree on the color wheel from 0 to 360 where 0 is red and the value ... View the full answer
