噪点测试卡落币图简介

　　分辨率测试卡落币图是枯叶图的变形，用于测试纹理清晰度。比起老版的枯叶图，它有几大优势:包含提高测试的精度，左右两边的灰色区域有助于去除噪点(使用的一种叫做灰块噪声的功率光谱密度是从中心溢出区域的信号和噪声总和的PSD中减去得到的技术。) 下面这几点是相对于枯叶图来说的几个优点：

　　Brief introduction of noise test card

　　Resolution test card The currency map is the deformation of the withered leaf, used to test the texture clarity. Compared to the old version of the dead leaf map, it has several advantages: including to improve the accuracy of the test, the left and right sides of the gray area to help remove the noise (using a gray noise called the power spectrum density from the central overflow area Signal and noise in the sum of the PSD minus the resulting technique.) The following points are relative to the wobble diagram for several advantages:

　　1.与枯叶图相比较，它包含对比度为2:1和4：1的斜边。

　　2.枯叶图左右两边的灰色区域和枯叶图案一样有着相同的密度。

　　3.包含16灰块和识别标记。线性化创建从0到255的17灰阶(类似于依据ISO12233标准的起草的西门子星状图)

　　1. It contains a bevel of 2: 1 and 4: 1 contrast compared to the withered leaf.

　　2. The gray area on both left and right sides of the withered leaves has the same density as the dead leaf pattern.

　　3. Contains 16 gray blocks and identification tags. Linearization Creates a 17-gray scale from 0 to 255 (similar to the Greek star chart based on the ISO12233 standard)
