Reconstruction of an RGB image.
Watch this File
In digital photography the red, green and blue values are not sampled at the same position. We can use demosaicing to reconstruct a "regular" RGB image.
This program is using bilinear interpolation for the reconstruction.
this code really helped me a lot~~Thx~
its good enough for understanding
Thanks very much!
That will give me a great help to understand bilinear interpolation algorithm!
Thanks very much
Basic but efficient function! A similar function is part of the Image Acquisition Toolbox (which I haven't tried)
Just add a ";" to the line "R = R + R1 + R2"
or you'll end upp waiting forever. ;-)
Also, for larger images you might want to clear variables (im, B1, B2, R1, R2) along the function to avoid the omnipresent "Out of memory" errors.
Just add a ";" to the line "R = R + R1 + R2
" or you'll end upp waiting forever. ;-)
Bi-linear interpolation is the most primitive demosaicing algorithm. Educational use is fine, but it is not suitable for high-end image processing.
