例如,如何在特定区域执行OCR
Rectangle Area = new Rectangle() {
X = 1367,
Y = 420,
Height = 57,
Width = 411
};
我必须从所有图像中仅从一个区域/矩形提取数据。我该怎么做?我试过IronOCR和Tesseract,效果很好。但我被告知使用莫迪。请帮忙。为什么你会考虑使用MODE,它一直被应用到Office 2007而不是像RoNoCR这样的最新工具?因为它不是我的决定。当然,但是我在文档、性能和稳定性方面说了。为什么你会考虑使用MODE,它一直被使用到Office2007,而不是像IronOCR这样的最新工具?因为这不是我的决定。当然,但我说过,从文档、性能和稳定性方面来说。
