图像聚焦程度对特征提取的影响
Influence of Degree of Image Focusing on Feature Extraction
摘要
Abstract
Texture analysis includes the quantitative calculation of the relationship among pixels in a local area of an image. "Shape" is one of the characteristics of the intuition is tic description of an object, which can be directly used to distinguish the target object. In this paper, the characteristics of "texture,""area," and "perimeter" of the infrared focus image are analyzed. The results show positive correlations of image area and image texture with the degree of focusing, while negative correlations exist with regard to the statistical second-order moment, entropy, and contrast of the texture. The relationship between the perimeter of the shape and the degree of focusing is weak. The texture and shape features of the extracted images vary at different degrees of image focus.关键词
