摘要
焦点测量是被动三维形状恢复方法的重要组成部分。本文分析了不同纹理反射率和光源照度下各种已建立的焦点测量方法。从文献中选择了五个重点指标。选取三种不同的微观物体进行纹理反射率测试。光源照明选择了三个不同的层次。在被动方法中，选取焦点形状法(Shape From Focus, SFF)对焦点测量方法进行深度估计的准确性和精密度测试。
Analysis of Effects of Texture Reflectance and Source Illumination on Focus Measures for Microscopic Images
Focus measures are an integral part for the passive 3D shape recovery methods. This paper presents an analysis of various well established focus measures with varying texture reflectance and source illumination. Five focus measures are selected from the literature. Three different microscopic objects are selected for testing the texture reflectance. Three different levels are opted for source illumination. Among the passive methods, Shape From Focus (SFF) is selected to test the focus measures for accuracy and precision of depth estimation.
