噪點測試卡落幣圖簡介

　　解析度測試卡落幣圖是枯葉圖的變形·╃，用於測試紋理清晰度▩☁◕。比起老版的枯葉圖·╃，它有幾大優勢:包含提高測試的精度·╃，左右兩邊的灰色區域有助於去除噪點(使用的一種叫做灰塊噪聲的功率光譜密度是從中心溢位區域的訊號和噪聲總和的PSD中減去得到的技術▩☁◕。) 下面這幾點是相對於枯葉圖來說的幾個優點✘•╃：

　　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.與枯葉圖相比較·╃，它包含對比度為2:1和4✘•╃：1的斜邊▩☁◕。

　　2.枯葉圖左右兩邊的灰色區域和枯葉圖案一樣有著相同的密度▩☁◕。

　　3.包含16灰塊和識別標記▩☁◕。線性化建立從0到255的17灰階(類似於依據ISO12233標準的起草的西門子星狀圖)

　　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)
