Automated lip reading from videos requires segmentation. Threshold-based segmentation is straightforward, but it rarely used. This study proposes a histogram threshold based on the feedback of shape information. Both good and bad examples were used to train an $$\epsilon $$ -support vector regression model infer accuracy region shape. The was optimised minimise error. proposed method tested 895...

In this paper, we describe an approach to estimate optic flow from an image sequence based on Support Vector Regression (SVR) machines with an adaptive e-margin. This approach uses affine and constant models for velocity vectors. Synthetic and real image sequences are used in order to compare results of the SVR approach against other well-known optic flow estimation methods. Experimental result...
