Binary and ternary textures containing higher-order spatial correlations
A quantitative method is presented for creating a large number of classes of binary (256) and ternary (7.62 x 10(12)) textures. The binary textures are presented as black and white (contrasts -1 and 1). The ternary textures have three levels: black, white and the mean luminance gray (contrasts -1, 0 and 1). The ternary patterns in particular display a wide variety of properties, including depth...
متن کاملGray-Level Reduction Using Local Spatial Features
This paper proposes a new method for reduction of the number of gray-levels in an image. The proposed approach achieves gray-level reduction using both the image gray-levels and additional local spatial features. Both gray-level and local feature values feed a self-organized neural network classifier. After training, the neurons of the output competition layer of the SOFM define the gray-level ...
متن کاملStatistical Analysis of Human Visual Impressions on Morphological Image Manipulation of Gray Scale Textures
A method of evaluating human visual impressions of gray scale textures using morphological manipulation is proposed. To study the effects of textural features on human Kansei, we introduced a texture analysis method based on mathematical morphology. Kansei is a Japanese word for sensibility or emotion. Kansei engineering is an approach to connect human sensibility with engineering applications....
متن کاملLevel set contour textures
Traditional texture mapping uses sampled images of limited resolution to represent patterns on surfaces. Sampling inherently assumes that the underlying pattern is band limited, which in plain language means that it must not contain any crisp edges. Unfortunately, most real world patterns violate that constraint, and the result is that texture mapped surfaces appear either artificially pixelate...
متن کاملStatic sound timing alters sensitivity to low-level visual motion.
Visual motion processing is essential to survival in a dynamic world and is probably the best-studied facet of visual perception. It has been recently discovered that the timing of brief static sounds can bias visual motion perception, an effect attributed to "temporal ventriloquism" whereby the timing of the sounds "captures" the timing of the visual events. To determine whether this cross-mod...
