Write an Android application for extremely simlpe photo manipulation

The app is for fixing the color of the image based on a properties of a chosen region.

.

1) The user import a photo.

2) The user draw a region on the screen

3) The algorithm (a simple 10 line algorithm) corrects the colors of the original image based on the region statistics

4) The user saves the new photo

Below is the matlab code that does the same thing I want the app to do. Just to show you how simple it is:

cdata; %original image

c1 = imcrop(cdata,[44.0160349854227 376.80029154519 115.935860058309 131.655976676385]);

rch = c1(:,:,1);

gch = c1(:,:,2);

bch = c1(:,:,3);

% Take the mean of each color channel in the cropped region

mean_rch = mean(rch(:));

mean_gch = mean(gch(:));

mean_bch = mean(bch(:));

% Take the mean of all three channels

mch = mean([mean_rch mean_gch mean_bch]);

% Calculate factor from each channel to get to the mean

rfactor = mch/mean_rch;

gfactor = mch/mean_gch;

bfactor = mch/mean_bch;

% Apply factor to the original image channels

newImg(:,:,1) = cdata(:,:,1)*rfactor;

newImg(:,:,2) = cdata(:,:,2)*gfactor;

newImg(:,:,3) = cdata(:,:,3)*bfactor;

imwrite(newImg,'[url removed, login to view]');
