Face Recognition Using Hidden Markov Models
matlab-recognition-code.com/face-recognition-using-hidden...
Abstract:
This dissertation introduces work on face recognition utilizing a novel method based mostly on Hidden Markov Models (HMMs). Through the mixing of a priori structural information with statistical info, HMMs can be utilized efficiently to encode face options. The outcomes reported are obtained utilizing a database of pictures of forty topics, with H coaching pictures and H check pictures for every. It is proven how commonplace one-dimensional HMMs within the form of prime-backside fashions might be parameterised, yielding profitable recognition charges of as much as round eighty five%. The insights gained from prime-backside fashions are prolonged to pseudo two-dimensional HMMs, which supply a greater and extra versatile mannequin, that describes a few of the twodimensional dependencies missed by the usual one-dimensional mannequin. It is proven how pseudo two-dimensional HMMs could be carried out, yielding profitable recognition charges of as much as round ninety five%. The efficiency of the HMMs is in contrast with the Eigenface strategy and numerous area and determination experiments are additionally carried out. Finally, the efficiency of the HMM is evaluated in a totally automated system, the place database pictures are cropped routinely.
