Image contrast ratio

The picture of harmony or lack of charm, is generally considered to be due to the dense lines contrast, the physical structure, Modeling image of a lack of integrity or lack of co-ordination ratio.

画面的不和谐或缺乏神韵，通常被认为是由于线条的疏密对比、形体结构、造型比例等方面不协调或是形象缺乏完整性。

Using this algorithm to dealing with weld image, the contrast ratio can be improved and the edges can be preserved well.

通过对焊缝图像进行广义模糊增强处理表明，该算法在增强对比度同时又可较好保持边缘。

The overlapping sensitivity matrix, area ratio (AR), reconstruction image, two-absorber model, and contrast-to-noise ratio (CNR) in different depths are used to evaluate the performance of PG.

论文采用重叠灵敏度矩阵、面积比、重建图像、双吸收组织模型、不同深度下的信噪比等评价参数，对提出的多边形探头分布模型的性能进行评估。
