Visual Psychology Research on the Invariant Feature and Performance of Texture Recognition

Abstract

Designed three visual psychological experiments to explore human ability on transformed texture discrimination and classical texture classification, and make some comparisons between human beings and computer algorithms. Some interesting results are obtained from these visual psychological experiments: (1) the invariance performance of sevral computer algorithms is appropriate to human beings; (2) texture is almost rotation invariant for human beings although single “b” and single “p” have significant different comprehension; (3) texture appearance depends on visual resolution. The biggest invariant scale of spatial scaling is roughly 2.3 times for human visual system at some fixed observation conditions; (4) some computer algorithms (such as MBF and Gabor) have achieved better performance than human beings under some restrictive conditions for fair comparison.
