然后是一个循环,循环次数为需要采集的样本数,摄像头拍摄取样的数量,越多效果越好,但获取以及训练的越慢。 循环内调用camera.read()返回值赋给全局变量success,和img 用于在GUI中实时显示。 然后调用cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)用于将采集到的图片转为灰度图片减少计算量。 然后利用加载好的人脸分类器将...

Now we used theimread()method to read our image, and in the next line, we overlaid the rectangle, which is the component, and then we overlaid our text to draw our rectangle. Therectangle()method takes the first parameter as an image. The next parameter we passed is theT_LEFTcoordinat...
text_recognition.py :我们的 OCR 脚本——我们将逐行查看这个脚本。 该脚本利用 EAST 文本检测器来查找图像中的文本区域,然后利用 Tesseract v4 进行识别。 实现OpenCV OCR 算法 我们现在准备好使用 OpenCV 执行文本识别了! 打开 text_recognition.py 文件并插入以下代码: ...
