摘要
为方便、准确地将数字图像中的曲线图转换为可以被计算机识别的、便于随时调用的曲线数据,论文提出一种基于图像处理技术提取图像中曲线数据的新方法,并利用Matlab编写出GUI程序。这种方法通过对图像进行灰度变换、二值变换、形态学运算的细化和重构,将数字图像中的曲线图提取出来,同时将曲线的数据(即曲线上点的坐标)以数组的形式保存为Matlab数据文件。之后即可在Matlab中通过插值法得到曲线上任意一点的值。
This paper presents a new method to extract the curve in image bases on image processing technology and a Matlab GUI program to execute it. This method can extract the curve in image conveniently and accurately. The extracted curve data can be recognized by com- puter and is convenient to be imported at any time. This method extracts useful curve in image by gray-scale transformation, binary image transformation, morphological thinning and reconstruction. Meanwhile, the curve data （coordinates） is stored as Matlab data file in the form of array. By this data, we can obtain any coordinate values on the curve in MATLAB by interpolation.
