Abstract:

Aiming at the specific objectives in face recognition, the authors proposed the BP neural network classification methods based on the Linex loss function, and presented the test results about face database of Cambridge as well. The image recognition experiments show that the traditional problems in specific target face recognition of BP neural network can be effectively solved the ORL by this method.
