Deep Learning Text Detection using OpenCV. The post is not only about detecting the text in an image but also about what is written in the text.
随着OpenCV 3.4.2和OpenCV 4的发布,我们现在可以使用一种名为EAST的基于深度学习的文本检测器,它基于Zhou等人的2017年论文“EAST:一种高效精确的场景文本检测器”。 我们将算法称为“EAST”,因为它是:高效且准确的场景文本检测管道。 据作者说,EAST管道能够在720p图像上以任意方向预测文本的单词和行,并且能够以13 ...

First we need to import opencv: 1importcv2 Let’s read an image in. You probably will have a color image, so first we need to convert it to gray scale (one channel only). 1image=cv2.imread("text_rotated.png") 2gray=cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) ...

The main idea of the segmentation-based text detection method is to obtain the text area in the image through the segmentation method, and then use opencv, polygon and other post-processing to obtain the minimum enclosing curve of the text area. Pixellink [7] uses a segmentation ...
