Filterpedia
Core Image Filter explorer
Filterpedia is an iPad app for exploring (almost) the entire range of image filters offered by Apple's Core Image framework. It is designed as a companion app to my upcoming book, Core Image for Swift which is due for publication in February 2016.
The UI is split into two sections: the table view on the left allows the user to navigate through and select a filter, the panel on the right then displays all the parameters of the selected filter which can be adjusted using horizontal sliders.
Filterpedia is also a showcase for custom filters I'm creating that are discussed in the book. These include simple compositions of existing CIFilter, CIKernel based filters using GLSL and filters that use Metal kernel functions as their filtering engine.
Core Image for Swift is available from:
