Questions

Try these questions to test your knowledge from this chapter:

  1. How can characters in non-English languages be recognized with Tesseract?
  2. When we used the EAST model to detect text areas, the detected areas were actually rotated rectangles, and we simply used their bounding rectangles instead. Is this always correct? If not, how can this be fixed?
  3. Is it possible to figure out a way to allow users to adjust the selected region after dragging the mouse while capturing images from the screen?
