Core Image is an image processing and analysis technology that provides high-performance processing for still and video images. Use the many built-in image filters to process images, and build complex effects by chaining filters. For details, see Core Image Filter Reference.
You can also create new effects with custom filters and image processors; see Core Image Programming Guide.
