SIP : a smart digital image processing library

The Smart Image Processing (SIP) library was developed to provide automated real-time digital image processing functions on camera phones with integer microprocessors. Many of the functions are not available on commercial camera phones and some are not found even in desktop image processing software. Five patents are pending for key functions in this library. These functions create realistic water reflections in varying weather conditions, perform localized magnification and pinching, transform photographs to perspective view, provide fast, high-quality spin radial blur, and provide a fast integer implementation for arbitrary rotation. Details on all pending patents are given in five chapters of this thesis. Other operations performed by the library include adding fog and shadow, creating a neon image, and creating a translucent comer fold. All library functions have been successfully implemented on an integer microprocessor for real-time performance in an existing camera phone system. The library also provides solutions to a number of long-standing problems in image processing, including direct application of transforms in subsampled YCbCr and YCrCb images.
