Image Processing in iPhone
In my iPhone app, I want to include image enhancement facility.
In a view, a user can see the selected image and from there, with the help of a slider they can set (brightness,contrast,hue,sharpness,saturation etc).
I don’t have any idea how to do this. I have googled it but could not find any good tutorial or source code.
Please help me if somebody has any idea.
I tried to use this-But when i add the classes from folder Curve, i cannot build my project-It shows build failed without showing any issue
I think what you want is GLImageProcessing. It uses openGL to do the Image Processing, but it is really fast.
If you want some code with Detailed Explanation then I found one Beautiful Link for you :
It’s like photoshop for the UIImage class!
You can also use CKImageAdditions.
Try this : GPUImage framework
Hope it will be helpful to you. Enjoy !!!
