METHOD AND DEVICE FOR CLASSIFYING AN OBJECT OF AN IMAGE AND CORRESPONDING COMPUTER PROGRAM PRODUCT AND COMPUTER-READABLE MEDIUM
First Claim
1. A method for classifying an object of a current image, a plurality of first landmarks representative of the shape of said object being associated with the current image, a first unique identifier being associated with each first landmark, the method comprising:
- for at least a first landmark selected among the plurality of first landmarks, obtaining at least a first descriptor describing an area of the current image comprising said at least first selected landmark,said at least first landmark being selected according to its first identifier,said at least first landmark being selected when its first identifier corresponds to a second identifier of a second landmark, a second descriptor of which being used in a classifier for classifying said object,determining information representative of confidence of said shape according to said at least first descriptor and according to weighting information associated with said second descriptor.

Abstract
The disclosure relates to a method for classifying an object of a current image, a plurality of first landmarks representative of the shape of the object being associated with the current image, a first unique identifier being associated with each first landmark. According to the disclosure, the method includes, for at least a first landmark, a step of obtaining at least a first descriptor describing an area of the current image having the at least first selected landmark. Then, the first landmark is selected according to its first identifier, and when its first identifier corresponds to a second identifier of a second landmark, a second descriptor is used in a classifier for classifying the object. Finally, the method determines information representative of confidence of the shape according to the first descriptor and according to weighting information associated with the second descriptor.
