Image thresholding python
WitrynaThe Viola–Jones object detection framework is a machine learning object detection framework proposed in 2001 by Paul Viola and Michael Jones. It was motivated primarily by the problem of face detection, although it can be adapted to the detection of other object classes.. The algorithm is efficient for its time, able to detect faces in 384 by … Witryna13 kwi 2024 · Here comes the Otsu’s binarization. This algorithm will allow you to quickly and automatically obtain the correct threshold value to choose between two histogram mode, so as to apply the thresholding in an optimal manner. In OpenCV, the application of the Otsu’s binarization is very simple. It will be sufficient to add as parameter within ...
