SIP : a smart digital image processing library
SIP: 智能数字图像处理库

Abstract
摘要

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.

智能数字图像处理库是为使用只支持整数运算芯片的具有照相功能手机而开发的。它提供自动实时数字图像处理函数。其中许多函数不仅在当前流行的具有照相功能手机中没有，而且即使在台式图像处理软件中也不存在。这个函数库中有5个关键函数正在申请专利过程中。这些函数包括：生成不同气候条件下的真实水面倒影，进行局部放大和捏合，对照片施行透视角度变化，提供快速高质旋转径向模糊，以及任意角度旋转的快速整数运算方法。有关所有正在申请专利的函数被分别详细描述于论文的5个章节里。其它库函数还包括加雾和阴影，产生霓虹图像，及做一个半透明的折角。全部库函数都在现有的, 带只支持整数运算芯片的具有照相功能手机上成功地实时测试过。这个函数库还对一些图像处理中长久存在的问题，比如把库函数直接应用于取子样的YCbCr和YCrCb不同模式图像，提供了解决方法。
