In RgbMotionDetection.java,

protected static boolean isDifferent(int[] first, int width, int height) {
...
                int pix = (0xff & ((int) first[ij]));
                int otherPix = (0xff & ((int) mPrevious[ij]));
...
                if (Math.abs(pix - otherPix) >= mPixelThreshold) {
 ...
                }

'pix' and 'otherPix' = 0xFF & color.
This method seems to compare only BLUE color.
Is below right, isn't it?
sorry my english.

int pixB = first[ij] & 0xff;
int otherPixB =  mPrevious[ij] & 0xff;
int pixG = (first[ij] >> 8) & 0xff;
int otherPixG = (mPrevious[ij] >> 8) & 0xff;
int pixR = (first[ij] >> 16) & 0xff;
int otherPixR = (mPrevious[ij] >> 16) & 0xff;
if (Math.abs(pixR-otherPixR) + Math.abs(pixG-otherPixG) + 
Math.abs(pixB-otherPixB) >= mPixelThreshold) {
...
}

What steps will reproduce the problem?
1.senseactivity is the main java class 
2.detector = new RgbMotionDetection(); this does not calls the 
RgbMotionDetection class
3.

What is the expected output? What do you see instead?
expected output: camera screen with detecting motion but i am getting an 
output: camera screen (but motion is not detected)

What version of the product are you using? On what operating system?
version 2.2(windows xp)

Please provide any additional information below.

i was wondering if you could make the code to run and detect motion as soon as 
possible , 
if you have an full working code you could send to this mail address 
[email protected] (or) [email protected]  that would help me a lot 

How to dectect right or left or top or bottom derection of motion?
