Examples of RgbAvgGray

jjil.algorithm.RgbAvgGray
Pipeline stage converts an ARGB color image into a Gray8Image. It does this by averaging the R, G, and B values. Note that since the byte image is signed, each unsigned byte in the ARGB word is converted to a signed integer before doing the average. So the word 0x00FF8001 would get R, G, and B values 127, 0, and -126 (and the average would be 0). @author webb
