Abstract
A method, medium, and apparatus with a generated object descriptor using a curvature gabor filter, with complementary object recognition being performed by applying a general gabor filter and a curvature gabor filter having various curvatures, such that the dimension and efficiency of a feature vector can be increased by detecting correlations between features of an object searching for a parameter and its position of an optimal curvature gabor filter through boosting learning, and projecting the extracted features onto a base vector having the highest classification rate.

7. A method of generating an object descriptor, the method comprising:
-
extracting first gabor features from a training object image by applying a curvature gabor filter to the training object image; selecting gabor features by performing boosting learning for object image classification with respect to the extracted gabor features and establishing a gabor feature set comprising the selected gabor features; generating a base vector by performing Linear Determination Analysis (LDA) of the established gabor feature set; extracting second gabor features from an input object image by applying a curvature gabor filter having the established gabor feature set to the input object image; and generating an object descriptor for object recognition by projecting the extracted second gabor features onto the generated base vector.
