| 摘 要： | 为了实现彩色图像到灰度图像的快速高保真转换,比较了几种现有的转换算法,分析了哪些因素限制着它们的转换速度以及它们是如何产生失真的.指出了提高转换速度的一般方法,包括采用合适的位图形式表示灰度图像、在VC 6.0中采取各种措施提高运算速度等.在此基础上,通过合理近似红、绿、蓝分量的权值,得到了保真度很高且转换速度很快的计算公式.实验比较了各种转换算法的转换效果、转换速度和转换误差,证明了新算法的优越性.

| Abstract: | To transform color images into gray images quickly and with high fidelity,factors that affect the transformation speed and fidelity were analyzed by comparing existing algorithms.Several methods universal for improving the speed of image transforming programs were proposed,such as expressing gray images in the most suitable bitmap form,developing programs with Visual C++ 6.0 and making full use of its features that could speed up the programs,and so on.Appropriate approximations were introduced to the weigh... |
