With Blurate you can create highly customized image filtering techniques.
OpenCL 1.2 graphics device required:
Provide the description of a filter in Blurate's graphical user interface by opening the KernelDesigner tool. It will craft OpenCL (TM) compute kernels to implement the filter description. You can apply the filter on your images.
Hold Alt key to enable wand functionality.
The filter descriptions can be saved, exported and reproduced on other OpenCL/Metal compatible devices.
And now you can transfer you filter designs to your iPhone.
