Along with high development of multimedia information technique, the provider of badness information embeds some badness information to image or directly saves as a image file, avoiding the filter of image, which brings extreme effect of security hidden trouble in society. An information audit system based on image content filtering is provided in this paper. At first, we discuss some basic met...

To model surface imperfections and weathering, we propose a two-step texture generation framework in between manual texture synthesis and automatic physical simulation. Although the pattern of blemishes looks random, the systematic and geometry dependent nature of the underlying distribution is still observable. A distribution of tendency (potential to contain blemishes) is modeled in the first...

The processes underlying the development of slant perception were investigated by manipulating the degree of texture element variability. Subjects at four grade levels were required to make judgments of physical slant of surfaces with three levels of variability. Absolute error of judgment decreased with age, but texture variability had no effect at any grade level. The results suggest that the...

The development of range scanning technology has offered new possibilities to capture large datasets in computer graphics. Due to physical restrictions, captured 3D objects can contain holes that need to be filled automatically. In a different area of interest, the field of texture synthesis, research has been done on a solution for a similar 2D problem. To utilize available methods, the challe...

The retrieval of images from a large database of images is an important and emerging area of research. Highresolution images in the physical database are decomposed into sets of image features which are stored in the logical database. Currently a few image retrieval systems combining color and texture as features to search images. In this paper 2D image is processed using a set of Gabor filter ...

The superelastic/shape-memory material, Nitinol, an approximately equiatomic alloy of Ni and Ti, is rapidly becoming one of the most important metallic implant materials in the biomedical industry, in particular for the manufacture of endovascular stents. As such stents are invariably laser-machined from Nitinol tubes or sheets rolled into tubes, it is important to fully understand the physical...
