![]() Get Hands-On Computer Vision with Julia now with the O’Reilly learning platform. We also use the CoordinateTransformations package to rotate the image around the center, as shown in the following code: using Images, ImageFeatures, CoordinateTransformationsimg1 = Gray.(load("sample-images/cat-3417184_640.jpg")). We not only explore ORB by using a similar example, as in the previous section, but also apply rotation to the second image. On top of that, the descriptor itself is enhanced and is rotation invariant. ![]() ![]() It gives an opportunity to select top N uncorrelated keypoints. The ORB descriptor is an improved version of BRIEF it is a mix of a FAST keypoint detector combined with a modified and enhanced version of BRIEF.Ī huge benefit of using ORB over BRIEF is the use of the harris corner measure that is built into ORB. ![]()
