查询词典 detecting

Feature of principal lines spatial distribution: detect the principal lines through edge detecting technology, and then divide the image of palmprint into blocks with same dimension, compute the mean and variance as feature; Feature of palmprint direction: divide the image into sub-images; compute the max angle of projection and coordinate of each sub-image, which stand for the direction and location of the line on the palm; Feature of moment invariants: compute the moment invariants of each sub-image and the whole image as feature.

掌纹主线空间分布特征：利用边缘检测技术检测出掌纹的主线，将图像分割成相同大小互不重叠的子图，提取每一个子图的均值和方差作为特征；掌纹线方向特征：将图像分成不重叠的子图，利用Radon变换求出每一个子图的最大投影角度和坐标，也就是子图内掌纹线的方向和位置，构造特征向量；掌纹不变矩特征：提取图像整体和分割后的子图的不变矩作为特征。

UV 254nm, 366nm and anisaldehyde as a chromogenic agent were used for detecting compounds of these strains. Results indicate that the metabolites of these strains were the most abundant when these strains were fermented in No.1 and No.4 media, and only few in No.2 and No.3. Metabolites of each strain were different in different media.
