In Best Fit Window,diffuse pixels cluster is obtained by using K-means algorithm in the five dimensions feature vector space: CIE L*a*b in-formation and pixel location information.

A simple and convenient method of diffuse reflection holography;

In order to improve the analysis efficiency, this paper studies the method of analyzing the composition of milk by using nearinfrared diffuse reflection spectroscopy and discusses the propagation of the light in the milk and some relevant measuring methods.

Ceramic materials have the advantages of good chemical stability,high-temperature resistance,size stability and light diffuse reflection.

The macro fractal characterization of the rough surface with low emissivity and high diffuse reflectance is analyzed by DFBIR model, and the macro fractal dimension is calculated by using SEM topography and graphic processing system S600.

This work has two objects:one is to expand the functions of infrared spectrophotometers so as to achieve the measurement of infrared diffuse reflectance at low cost;the other is to complement the means for measuring the infrared diffuse reflectance in the waveband from 2.

This paper introduces a method of the measuring for material diffuse reflectance by integrating sphere, hereby a practical instrument is designed.
