Index out of bound exception occured when new SURF object is created with BufferedImage with alpha channel as a parameter.

[GoogleCodeExporter]

What steps will reproduce the problem?
================================================
1. Create a new surf object: new Surf(bi); Where bi is a buffered image with 
alpha channel

What is the expected output? What do you see instead?
================================================
Array index out of bound exception occurred.

What version of the product are you using? On what operating system?

Please provide any additional information below.
================================================
To fix the issue file IntegralImage.java on line 96 must be changed:

int[] pixel = new int[3];  => int[] pixel = new int[4];

Cause there is 4 possible colour channels in BufferedImage in general case.

IntegralImage.java as per your suggestion, thanks for catching this!
