Methods based on spatial frequencies , co - occurrence matrixes and multiresolution methods have been frequently employed for texture description because of their efficiency [ 3 . 69 ] 这些方法基于空间频率,共生矩阵及多分辨率法由于效率高而常被纹理描述运用。
It is more efficient to use texture feature to describe an image with complicated textural contents . grey co - occurrence matrix , which is a 2d color statistical feature , is often used to analyze such images 对富含纹理图像,采用纹理特征表达会更有效,颜色的二维统计方式?灰度共生矩阵是常用方法。
This algorithm first extracted the texture characteristic vectors of leather using co - occurrence matrix , then clustered the characteristic vectors using modified fcm , this algorithm can detect the defects on leather exactly 该方法首先采用共生矩阵提取皮革的纹理特征向量,然后用改进的模糊c -均值算法对特征向量进行聚类分析,该算法可以准确的检测出皮革表面的缺陷信息。
For evaluating the skin texture objectively , a novel measuring and recognizing model for skin texture is founded based on adopting spatial gray level co - occurrence matrix of image texture analysis to extract important features of skin texture 摘要为了可观地评价皮肤的质地,采用图像纹理分析中的空间灰度共生矩阵法提取皮肤纹理图像的重要特征,建立一种新的人脸皮肤纹理的测量识别模型。
the temporal property of two things happening at the same time; "the interval determining the coincidence gate is adjustable" 同义词:concurrence, coincidence, conjunction
Co-occurrence or cooccurrence is a linguistics term that can either mean concurrence / coincidence or, in a more specific sense, the above-chance frequent occurrence of two terms from a text corpus alongside each other in a certain order. Co-occurrence in this linguistic sense can be interpreted as an indicator of semantic proximity or an idiomatic expression.
