Atitit  图像处理Depixelizing Pixel Art像素风格画的矢量化 在去年的时候,偶然看到hqx算法. 一个高质量的插值放大算法. 与双线性插值等插值算法相比,这个算法放大后对人眼保护相对比较好. 没有双线性插值看起来模糊,固然,也抽空把算法简单优化了一下. 常规的图像填充采样放大 "经典"的图像填充采样放大,应用线性滤波器,或导出于分析插值理论.或导出于信号处理理论.使用滤波器的实例,比如"最近邻,Bicubic和Lancosz [ Wolberg 19…

片元着色器(Fragment Shader)被称为像素着色器(Pixel Shader),但片元着色器是一个更合适的名字, 因为此时的片元并不是一个真正意义上的像素.…

QImage repairImg(width, height, QImage::Format_Mono); ; row < height; row++) { // uchar* ucRow = maskImg.scanLine(y); ; col < width; col++) { repairImg.setPixel(col, row, (qRed(maskImg.pixel(col, row)) == ? : )); } } 之前参数 col 和 row 给反了,,搞了俩天各种查资料,,问…

去年有这样一个工具,We got one toolkit last year. 他有什么功能呢?What is its function? 让你画出各个方向的照明图 That you can draw lightmap from different directions. 然后处理And process it with the tool. 就可以得到一张法线图,可以用来光照了So you can got a normalmap,that can be use for light. 就一个这,我很…

中文名称:体素,即顾名思义是体积的像素.用来在三维空间中表示一个显示基本点的单位.类似于二维平面下的pixel(像素). voxel是三维空间中定义一个点的图象信息的单位.在平面中定义一个点要两个坐标X和Y就够了,而在三维世界中还要有一个坐标.光有位置还不行,还要有颜色等信息,这就是voxel的含义. A voxel is a unit of graphic information that defines a point in three-dimensional space. Since a…
