20 Jun 2014 3D Rigid body transformation This program is for rigid body transformation of 3D objects. Author: Jeny Rajan John

A couple of points:
1) It does not interpolate. This is okay for translations with this script because all translations are in integer quantities in each axis. But the lack of interpolations mean rotations will produce some unexpected artefacts.
2) You have to go into the code to add a fill value for shifted in data.
3) SLoooooooooooow!
4) No documentation, so you have to torture yourself with mental tetris + trial and error to figure out how axes are set in this script

If you want to do 3d rigid transformations, your best bet is to use the Image Processing Toolbox's imwarp function, after specifying the centroid/frame origin. It provides functionality for interpolation (very important!). Also take note of what value it inserts to shifted in data when translation happens. Imwarp takes care of the fill values too. I know, MATLAB charges big bucks for it, but they have a perfect, efficient, and well documented implementation in imwarp. Yes, it's also a little bit more work to figure out imwarp - no pain no gain.

I gave the script a 1 star rating. That star is for participation!

21 Apr 2014 Image Denoising using Fourth Order PDE Denoise images based on fourth order partial differential equations. Author: Jeny Rajan Yulius Harjoseputro

hi, i'm very interested about your program. I have download example code in your program but I get error like this :

Error in gradient (line 49)
[err,f,ndim,loc,rflag] = parse_inputs(f,varargin);

Output argument "varargout{2}" (and maybe others) not assigned during call to "C:\Program
Files\MATLAB\R2013a\toolbox\matlab\datafun\gradient.m>gradient".

Error in fpdepyou (line 20)
[Ix,Iy]=gradient(I1);

Can you help me please to fix this error?

01 Nov 2013 program Color balancing A simple program for color balancing Author: Jeny Rajan Nicolas

The function is badly written. There are unused variables lying around, and the 2 for loops could be removed in favor of the usual Matlab tricks for computational efficiency.
The results are not that visually satisfying either - the color temperature is definitely off on some of the images I tried this function on.

04 Apr 2011 program Color balancing A simple program for color balancing Author: Jeny Rajan Austin

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.
