iOS Core Image Tutorial And Example Page

The Core Image framework was added to the iOS 5 developer SDK adding a multitude of image processing API’s previously only available on Mac OS X.

Core Image provides pixel level image filters, and allows for many different filters to be placed upon an image at the same time.  These include not only image filters for special effects such as bloom or motion blurring, but other image processing algorithms providing for features such as face detection. This means that in many cases where you either had to use a library such as OpenCV or write your own code for image processing within iPhone and iPad apps you can now use the Core Image API.

If you’ve created an iOS Core Image tutorial with a sample project that you would like listed on this page you can submit it here.

You can find Apple’s official documentation for Core Image on the iOS platform here, that includes nice listing of available filters.

Check out the iOS 5 tutorial page for tutorials on other topics within the iOS 5 SDK.

I test out each Core Image example or tutorial to make sure that everything works.  If you have any issues please post them in the comments at bottom.
