We propose a simple technique for extracting dominant foreground objects from images in this paper. Image foreground segmentation is a challenging task given problems due to complex background, clutter and occlusion, spectral variability in object appearance etc. Most of the techniques in this respect are semi-automatic in nature which require prior assumptions regarding the object location in the...
For visual feedback of articulatory efforts in speech training aids, the vocal tract shape can be estimated by LPC analysis of the speech signal. The vocal tract is modelled as a concatenation of equal length sections and the ratios of the areas at section interfaces are calculated and these are scaled using the area of a reference section. The lip opening area as estimated from a video recording...
