彩色边缘 meaning in Chinese

color fringing

In this thesis , cedo ( color edge detection operator ) operator is given on the basis of modifying the color edge detection operator , which is provided in literature [ 11 ]
本文在借鉴文献[ 11 ]的基础上，对其提出的彩色边缘检测算子进行了改进，给出了cedo ( coloredgedetectionoperator )算子。
The method firstly uses color edge detector to get the horizontal edge image , secondly it makes use of the global threshold method binary quantifying the grad image , and finally dilates the binary grad image from horizontal direction
该方法首先利用彩色边缘算子colorprewitt提取了图像的水平边缘,然后利用全局阈值法对梯度图像进行了二值化,最后对二值梯度图像进行了形态学水平膨胀。
So the text exaction of color image is preferably accomplished in this thesis , after intensive description of text extraction from color image , the system based on a simplification model is investigated . it includes the detail processing : image preprocess , color edge detection , threshold calculation , binary processing , candidate text region formation and extraction
本文对彩色图像的文本提取进行了比较透彻的阐述后，在一个简化模型基础上，详细描述了彩色图像文本提取系统的处理流程：预处理、彩色边缘检测、阈值计算及二值化处理、候选文本区域生成、文本区域提取。
