Opencv hed edge detection
Web22 de fev. de 2024 · Currently, the Structured Forests edge detection algorithm is not a part of the stable OpenCV library, which is the opencv-python 4.5.1.48 at the time of writing. Instead, it is part of the opencv-contrib package. So, before moving ahead, you need to install the opencv-contrib-python package from PyPi. Web7 de jan. de 2024 · I am using openCV and Canny edge detection and it works ok but if I try to scan an document on a background without enough contrast between the document and the background it fails. I have tried other apps in the Play Store and they are still able to scan the document with less contrast.
