这个程序使用opencv text模块识别图片里的单个英文字符。输入图片:程序运行后显示识别结果和对应的置信度代码#include opencv2/text.hpp #include opencv2/highgui.hpp #include opencv2/imgproc.hpp #include iostream int main() { Mat image imread(scenetext_char01.jpg); PtrOCRHMMDecoder::ClassifierCallback ocr loadOCRHMMClassifierCNN(OCRBeamSearch_CNN_model_data.xml.gz); string vocabulary abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789; vectorint out_classes; vectordouble out_confidences; ocr-eval(image, out_classes, out_confidences); cout vocabulary[out_classes[0]] : out_confidences[0]; return 0; }OCRBeamSearch_CNN_model_data.xml.gz在text模块里有提供。
