Curvature Histogram Features For Retrieval Of Images Of Smooth 3d Objects
1ST INTERNATIONAL SCIENTIFIC SCHOOL ON METHODS OF DIGITAL IMAGE PROCESSING IN OPTICS AND PHOTONICS(2014)
摘要
We consider image features on the base of histograms of oriented gradients (HOG) with addition of contour curvature histogram (HOG-CH), and also compare it with results of known scale-invariant feature transform (SIFT) approach in application to retrieval of images of smooth 3D objects.
