代码说明:

单幅图片的高光去除是一个非常有挑战性的课题。以前的绝大多数方法,要么需要进行图像分割等预处理,要么要求用户进行交互输入。本作品的方法,从高光图片的颜色统计规律出发,发现了最大漫反射色度局部平滑这个特性,从而可以使用低通滤波对最大漫反射的值进行扩散传播,从图像中的漫反射的像素传播到镜面反射的像素。最终得到全图的估计最大漫反射色度,求出图像中每个像素的漫反射分量。与传统方法相比较,此方法非常简单,适合并行,在GPU上执行效率非常高。

The first point of the center on the ellipse at the origin is calculated. 3. According to formula (1.1.3-2), the initial value of decision-making parameters in region 1 is calculated. 4. At each location in region 1, the decision-making parameters are updated repeatedly according to formula (1.1.3-3). If the decision-making parameters are less than 0, they will remain unchanged. If the decision-making parameters are less than 0, then add 1 and cycle until the first point satisfying this condition is (); 5. At each location of region 2, the decision parameters are updated repeatedly according to the formula (1.1.3-6). If the decision parameters are less than 0, they will remain unchanged.

    这本书是专门为黑客基本的分析程序使用调试器和汇编器的方法。这是有问题的巨大兴趣,但在现实中,很少有对谁掌握了专业水平,这些方法的程序员。(This book is dedicated to the basics of hacking—methods of analyzing programs using a debugger and disassembler. There is huge interest in this topic, but in reality, there are very few programmers who have mastered these methods on a professional level. )
