A new method for auto seal authentication with a new image capture device is presented. Different from traditional one, the seal is separated into several sub-blocks, then DCT signs indexed by the locations that we selected under a rule are checked for all of these blocks. Hence the block, that is, the location of doubtful part on the seal image in the authentication result is also able to be output...
A face identification method using the sign of non-orthogonal transform is proposed. In our previous work, the sign of orthogonal transform is exploited for face identification. The orthogonal transform has a good characteristic to concentrate the energy in low frequency area, it is good for image compression because of orthogonalization. However, for face identification, what we care about is how...
Face authentication using orthogonal transform signs is presented. The nature of the real orthogonal transform sign is utilized here. Employed transforms are typical and well known ones, ie., DCT, Walsh-Hadamard, Karhunen-Loeve transform and binarized Fourier transform. The face authentication is done by making a very simple and short binary sequence which is called have "bar-code". The...
Recently, the research of the identification technology using biometrics has done actively for the counterterrorism and the security improvement. In many kinds of biometric identification methods, since face identification is of non-contact and little psychological resistance one, and several such products are put out to the world. On the other hand, to read the feelings state of human being, the...
