| 摘 要： | 按照２ＤＧａｂｏｒ函数的特点和视觉机制，提出了用来捕捉纹理基元的纹理检测器函数，然后基于纹理检测器和新近发展的小波多尺度分解理论，提出了影象纹理的多尺度分析方法，并按照神经动力学的侧抑制和端点抑制等理论，建立了对多尺度纹理特征的融合方法。这一多尺度纹理分析方法在介于空间域和付里叶域之间，为纹理分析提供了一个层次性的分析框架，能够检测不同尺度的纹理信息并与视觉纹理处理机制相一致，有效地提高了纹理的识别能力。

| Abstract: | It is important to consider the role of scale for texture analysis. In this paper, a texture detector based on 2D Gabor function and visual textural perception is established first, then based on the texture detector and wavelet theory of multiscaledecomposition, a multiscale texture analysis method is proposed, and techniques formultiscale texture feafure fusion are advanced according to the lateral inhibition andend-inhibition in neurodynamics. The multiscale texture analysis techniques give representations between spatial space and Fourier space, and provide a hierarchical analysisframe for image fexture. They can detect different scale textural features, correspondsto the visual texture perception, and have the ability to recognize textureimage effectively. |
