Text detection/recognition in images with EAST/Tesseract

Text detection refers to an image processing task that detects and localizes the bounding box coordinates of texts contained in an image. Extracting and understanding textual information contained in images has become important and popular. Text detection serves as a preprocessing task for it. In this recipe, you will first learn to detect text in an image with a pretrained deep learning model (called EAST) and then recognize text using pytesseract and opencv-python library functions.

The EAST (which stands for Efficient and Accuracy Scene Text detection) text detector is a powerful pipeline for accurate and fast text detection. The model is an FCN (a single deep neural net) that directly predicts the bounding boxes for the words/text lines present in the input image (with arbitrary orientations), thereby eliminating unnecessary...
