Texture analysis is a basic issue in image processing and computer vision, and how to attain the Rotation-invariant texture characterization is a key problem. This paper proposes a rotation-invariant texture analysis technique using Radon and Fourier

Visual cognition results from the interaction between objective images and cognitive subjects. In this paper, the concept mental connectivity of visual imagery is proposed for the first time, based on which a novel interpretation of the visual invari

The paper successfully explains why the Einstein-Monroe picture has two interpretations when the viewing distance or eyesight is changed from the view of spatial frequency. We use the Contrast Sensitivity Function (CSF) and the Abbe theory of image i

In this paper, an explanation based on a power law between the average power spectrum and spatial frequency is proposed to reinterpret the three famous experiments on primitive visual perception involving the prior perception of global topological pr

Visual Computational Theory that was founded by Marr plays an extraordinarily important role in Visual Science. There is still lot of research to do for this theory, such as building it in spatial frequency domain. Our research will be mainly on Visu

We apply a biologically inspired model of visual object recognition to the object translation invariant problem. Our model modifies that of Serre, Wolf, and Poggio. This biologically inspired model is hierarchical, formed after the division of the hu

As an important problem in human visual research, visual invariance has not been explained well in essence yet. Hierarchical receptive field model which could explain a part of visual invariance was considered as a fixed structure comprised of differ
