slope features meaning in English

斜坡及挡土墙

The main works are described as follows : ( 1 ) we have summarized the latest research achievements and development of fractal theory and the applications in image processing domain and discussed and studied the definition , principle and algorithm of fractal and fractal dimension ; ( 2 ) aiming at the disadvantages of dfbr based edge detection method , an algorithm based on fractal intercept feature was put forward ; moreover , aiming at the bad anti - noise performance of traditional methods , a edge evaluation method was introduced to evaluate the performance of the algorithm and that of sobel - based algorithm quantificationally ; ( 3 ) furthermore , we proposed a novel method based on slope feature and intercept feature , then compared the performance with that of intercept - based method
通过对近年来国内外学术界对分形理论及其在图像处理领域相关应用问题的研究成果和最新进展的搜集、整理和总结，对分形及分形维数的定义、原理、算法以及在图像处理上的应用进行了较为系统的研究和探讨； 2针对基于dfbr场边缘检测典型算法的缺点，采用了一种基于分形截距特征的图像边缘检测算法，取得了较为满意的结果；并针对传统方法抗噪性能差的缺点，引入一种基于参照图的边缘评价方法，并对此算法性能与传统sobel算法进行定量分析对比，实验证明该算法是有效的； 3
