Witryna文本识别是OCR（Optical Character Recognition）的一个子任务，其任务为识别一个固定区域的文本内容。在OCR的两阶段方法里，它接在文本检测后面，将图像信息转换为文字信息。具体地，模型输入一张定位好的文本行，由模型预测出图片中的文字内容和置信度，可视化结果规则文本识别和不规则文本识别。

Reading and Displaying an image in OpenCV using C++

Witrynaimshow (Im,R) displays the image Im with associated 2-D spatial referencing object R. The first argument Im can be a grayscale image I, truecolor image RGB, binary image BW, or the name of the file filename for an image of one of those types. Witrynaimshow(X,map) displays the indexed image X with the colormap map. A color map matrix may have any number of rows, but it must have exactly 3 columns.
