This work explores the possibility of modeling tonal stability from music signals, in an attempt to approximate in a different way an ubiquitous, yet controversial, topic in music research: that of the perception of tension and relaxation over time. We rely upon some of the most agreed hypothesis about the hierarchical properties of the tonal system, to define a scenario in which such features ...

In this paper, the effect of lightness on blackness preference of 216 black fabrics prepared by printing method is investigated. 18 observers including of 9 males and 9 females are asked to firstly rank order black fabrics with the same lightness values according to their preference. In the next step, observers are asked to define their blackness preference for blacks with different L values. R...

In this paper, we proposed a new region extraction method using chroma key with a two-tone checker pattern background. This method solves the problem in conventional chroma key techniques that foreground objects become transparent if they have the same color with the background. The method utilizes the adjacency condition between two-tone regions of the background and the geometrical informatio...
