For the first time in this paper we present results showing the effect of speaker head pose angle on automatic lip-reading performance over a wide range of closely spaced angles. We analyse the effect head pose has upon the features themselves and show that by selecting coefficients with minimum variance w.r.t. pose angle, recognition performance can be improved when train-test pose angles differ...
Study on Activities of Daily Living(ADLs) can be used in many research fields, but it is very complex. In this paper 40 basic ADLs were summarized by collecting and analyzing all the ADLs of human body. Then the experiments on 9 healthy adults who performed these 40 activities were conducted. All the procedure was recorded by using a digital vidicon. As a result 17 typical basic actions were obtained...
This paper describes a new simple, but effective, approach to speaker verification using video sequences of lip movements. We use motion history images (MHI) to provide a biometric template of a spoken word for each speaker. Class-dependent correlation filters are then created by a weighted optimization of training MHI samples. Feature extraction is performed by correlating a test MHI against each...
