Options

• Desc Type of descriptor to use, '120' is default (120 dimensions float). Available types are:
  • 120
  • 80
  • 64
  • 48
• Sigma Gaussian kernel value for image blur. default is 1.4
• ImgNormalize Use image sample intensity normalization. default true
• UseScaleOrientation Sample patterns using keypoints orientation. default true
• ScaleFactor Adjust the sampling window of detected keypoints to 64.0 (VGG sampling window).
  • 6.25 is default and fits for cv.KAZE, cv.SURF detected keypoints window ratio
  • 6.75 should be the scale for cv.SIFT detected keypoints window ratio
  • 5.00 should be the scale for cv.AKAZE, cv.MSDDetector, cv.AgastFeatureDetector, cv.FastFeatureDetector, cv.BRISK keypoints window ratio
  • 0.75 should be the scale for cv.ORB keypoints ratio
• DescNormalize Clamp descriptors to 255 and convert to uint8. default false
