Claim 19:
20. The system of claim 19, wherein the detection model for the specific type of fake palm is trained based on training data to recognize the specific type of fake palm, wherein the training data include a plurality of pairs of an actual palm image and a fake palm image of the specific type, wherein the training comprises:
for each of the plurality of pairs,
concatenating the actual palm image and the fake palm image to create a concatenated image,
extracting global features from the concatenated image,
identifying ROIs in the palm and fake palm images,
extracting local features from the ROIs respectively,
grouping the local features for different ROIs,
fusing the global features and grouped local features,
classifying with respect to the specific type of fake palm based on the fused features,
receiving ground truth associated with the pair, and
adjusting parameters of the detection model based on the classification and the ground truth.
