电气工程图纸矢量化技术滤波算法的研究分析

摘要

电气工程图纸的矢量化是指将图纸上模拟量的符号，转化为计算机能识别的数字量。在研究各种低通滤波算法的基础上提出利用小波对电力工程图纸进行滤波的算法，用Matlab语言进行算法实现。试验结果表明：利用小波低通滤波方法对含有噪声的电力工程图像进行处理，可行且有效。%The vectorization for electrical engineering drawings refers to the conversion of analog symbols in the drawings into digital values that can be recognized by computer. This paper puts forward a filtering algorithm on electrical engineering drawings with wavelets on the basis of researches on various low pass filtering algorithms. The algorithm is realized with Matlab language. The experimental results show that the method of processing power engineering images with noise with wavelet low-pass filtering is feasible and effective.
