Feature detection using Oriented FAST and Rotated BRIEF ORB Algorithm in OpenCV with Python
Feature detection using Oriented FAST and Rotated BRIEF ORB Algorithm in OpenCV with Python.
A feature can be described as a small patch in the image, which is invariant to image scaling, rotation and illumination. This way, the same feature can be detected from different images of the same scene with different perspectives. Therefore, a good feature should be the following:
Repeatable and precise (the same feature should be extracted from different images of the same object).
Distinctive to the image (images with different structures will not have this feature).
