如何从图像中检测文本区域?
我想从图像中检测文本区域作为 tesseract OCR 引擎的预处理步骤，当输入仅为文本时引擎运行良好，但当输入图像包含非文本内容时，它会下降，所以我只想检测文本内容图像，任何关于如何做到这一点的想法都会有所帮助，谢谢.
i want to detect text area from image as a preprocessing step for tesseract OCR engine, the engine works well when the input is text only but when the input image contains Nontext content it falls, so i want to detect only text content in image,any idea of how to do that will be helpful,thanks.
