纹理研究综述

纹理精确定义困难，但存在被广泛认同的性质。结构法、统计法、频谱法和模型法是常用的纹理研究方法。结构法从纹理的基元形态及其排布规则角度分析，适用于研究规则纹理；统计法从宏观角度对纹理进行统计分析，适用于随机纹理；频谱法利用频域信号处理方法分析纹理的数字特征；模型法将纹理看做某种数学模型进行分析。纹理研究已广泛应用于军事、工业、农业、医疗等方面。为此，从定义、特征、研究方法、应用领域几个方面对纹理的研究现状进行了论述。

Summary of texture research

There are some features widely accepted by the researchers though it is quite difficult to define texture accurately. Structure analyzing, statistical analyzing, spectrum analyzing and model theory are the four methods mainly used in texture research. Structure method is usually used to analyze the regular texture by identifying the texture elements and their distribution. Statistical method is suitable to the random texture by analyzing the statistical features from a macro point of view on the contrary. Texture digital features are got by using some signal process theories in spectrum field. Texture is considered as some mathematics models in model texture analyzing theory. Texture applications are widely used in military, industry, agriculture and medical areas. This paper discussed texture definition, features, research methods, application research status.
