光栅图像(Raster Images)用数组下标存储每个像素的2D中心位置,位置起点 (0,0) 根据不同API分为左下和左上 n_x\times n_y 图像像素范围: Range=[-0.5,n_x-0.5]\times [-0.5,n_y-0.5] 3.2.1 像素值(Pixel Values) (1)像素值:浮点数存储,用于记录internsity 灰度图,1维浮点即可 彩色RGB,3维浮点 ...
矢量图像通常用于文本、图表、机械制图和其他应用,在这些应用中,清晰度和精确度非常重要,而不需要照片图像和复杂的着色。 在本章中,我们将讨论光栅图像和显示的基础知识,尤其关注标准显示器的非线性特性。在后面几章讨论计算图像时,我们需要了解像素值与光强度之间的关系。 3.2 Images,Pixels,and Geometry 我们知道,光...
