摘要
针对印章会影响发票文字识别的问题,提出了一种基于Pix2Pix网络去除印章的方法:采用HSV颜色空间的方法,筛选出包括印章在内的信息;通过二值化、图片腐蚀、轮廓集检测、椭圆拟合算法,确定椭圆印章的位置;将检测到的印章位置的外接矩形作为图片送入Pix2Pix网络,得到去除印章的图片。实验结果表明,Pix2Pix网络可以有效地去除印章。
To solve the problem that the seal will affect the recognition of invoice characters,a method of removing the seal based on Pix2Pix network was proposed.The HSV color space was used to filter out the information including seal.The location of ellipse seal was determined by binarization,image erosion,contour set detection and ellipse fitting algorithm.The external rectangle of the detected seal position was sent into Pix2Pix network as a picture,and the picture of the seal removed was obtained.The experimental results show that Pix2Pix network can effectively remove the seal.
