No commenting of any kind in the file! No description! Mileading keywords. Color or white balances require a calibration file. This does not so is useless.

good!

the effect is good enough,better than some comercial software in China ,for exmaple neo imaging.theory based on a taiwan paper on IEEE

The program is good. But computationally intensive.

Thanks this was useful. This script is slow only because of the first double for-loop doing a dynamic memory allocation each time the condition is met. MATLAB is terrible with dynamic memory allocations. Simply add:

Ciny = zeros(1,x*y);

right before the outer for loop (for i=1:x), and then add:

Ciny(cnt:end) = [];

right at the end of the for loop (right above cnt=cnt-1; and then the sort) to get rid of the unused memory. This speeds up the code tremendously.

Thanks.

very good
