iOS Image Processing in iPhone

[rickjackson]

Hello to all,

Actually I am adding Image Processing Feature in my iPhone Application It should do Brightness, Contrast, Sharpen, Exposure....

But i am not able to Find any article/Tutorial on the Internet. Will you please help me to find any tutorial or tell me how can i implement the iPhone View Based Application.

I have found 1 link http://www.iphonedevsdk.com/forum/i...094-adjust-image-brightness-contrast-fly.html its worked also for Brightness but its not working on iPad.

So Suggest something that i can start with my Image Processing Logic.


Thanks

Rick Jackson

Image from camera or from a file?

Do you want to get an the raw RGB bitmap values, and apply some 2D mathematical filtering functions using the Accelerate framework and/or your own DSP code, or try doing something with the GPU?

Do you want to work in the RGB, YUV or HSV (or some other) color space?

Thanks

I suggest a good textbook on video and image processing so that you understand the terminology, data types and algorithms that you may need.

Too many people ask for a programming solution without finding out that it's a standard textbook subject or maybe a typical graduate student term project.
