查询词典 characterize

First, based on all that have been mentioned above, the geometric constant D, which was introduced to characterize the quantitative difference between Birkhoff orthogonality and isosceles orthogonality, is studied further. Moreover, attainability as well as continuity and monotony of D in two-dimensional sequence spaces are presented.

In order to effectively abstract the texture and denoise but not damage the edge and other important details of image, Meyer (2001) proposed using elements of BV space and G space to characterize cartoon and details of image respectively.
