The paper presents some methods of reducing coding time in neighborhood matching, selecting contrastdegree scale, pre-dealing.
该文从邻域匹配、对比度因子的选取、预处理等方面提出了一些降低编码时间的方法。

The main reason is that the resolution and contrastdegree of the ultrasonic image itself is very low as well as the influence of intrinsic speckle noises.
其原因主要是超声图像本身分辨率、对比度较低，以及固有的斑点噪声的影响。

The final research shows that the lower the contrastdegree, the lower the entropy decreases and the higher the energy increases with decreasing the pilling of fabric.
