Applying 1st and 3rd order equations to images

[Steve.Briggs]

Hello all,

It has been quite some time since I have programmed with LabView in any detailed manner so I post this question to the masses in hopes of a quick and easy solution.

I am trying to replicate optical aberrations (1st and 3rd order monochromatic - to be specific).  I am hoping to replicate this on a standard concentric square target and a circular concentric square target (images attached).  In terms of applying a set of equations to an image and seeing the new "distorted" image, what would be the best method of going about this?  I was able to get some success with converting the image to an array and applying the equations to the array and converting back, but the results were disappointing.  Next I worked with the image and pixel manipulation to no real effect.  In the past I could apply some kernels to a small sample set and effectively alter the trigonometry and geometry.

If anyone has some quick insight to this I would greatly appreciate it.  Simplifying my rubbish above, I basiaclly just want to apply some squared and quadratic equations along with some trigonmetry to distort my concentric squares/circles.

Best,

Steve

Hey Steve

I looked around and it was hard to find any examples, so I started working on a pretty simplistic version of what I believe you are trying to do. 

I attached the code, as well as a raw data bitmap of one of your images. The main VI is DrawPicture.vi .  The default values should be set to an interesting image.  I put it together pretty fast, so please be aware that it's untested, and probably not very optimized. 

I just hope this is what you are looking for, and if you have any questions, let me know.  I'll do my best to get back to you, though I will be out of the office for a while, but I will try to check back in when I can.
