λ((u,s);x)=  f (x) f (x\(u,s)) if (u,s) is one of the elements of x, f (x∪(u,s)) f (x) otherwise. (A) Evaluating this conditional intensity λ efficiently is thus a critical requirement. One should stress that the ratios f (x\(u,s)) f (x) and f (x∪(u,s)) f (x) are of course not computed directly but after simplification of the many common terms that are on both sides of the fractions. More exp...

This paper present a texture compression technique for still images based on the wavelet transform and the auto-regressive (AR) texture model in order to increase the compression ratio with a minimal loss of image quality. First the influences of the initial condition and the order of an AR model on the resulting texture model are investigated to serve as a theoretical foundation for the propos...

This paper presents a new texture analysis method based on structural properties. The texture features extracted using this algorithm are invariant to affine transform (including rotation, translation, scaling, and skewing). Affine invariant structural properties are derived based on texel areas. An area-ratio map utilizing these properties is introduced to characterize texture images. Histogra...

This paper utilizes a spatial texture correlation and the intelligent classification algorithm (ICA) search strategy to speed up the encoding process and improve the bit rate for fractal image compression. Texture features is one of the most important properties for the representation of an image. Entropy and maximum entry from co-occurrence matrices are used for representing texture features i...

We present an alternative to traditional texture compression techniques whereby a clear data channel is embedded within a texture using steganographic techniques. The resulting pixels are polymorphic – they can be used without decompression and the embedded data can be extracted and used for alternative purposes. The technique has fewer degenerate cases than DXT, does not suffer from high-frequ...

S. T. Yang, M. Zhou, T. Jiang, X. X. Xue, P. N. Duan, W. J. Zhang: School of Metallurgy, Northeastern University, China Melting behavior is the precondition of liquid phase reaction, which is the foundation of sinter consolidation. Melting property measurement and sinter pot test were adopted to determine the melting temperature and strength of sinter with 13 % and 40 % vanadium-titanium ore ad...

BACKGROUND AND PURPOSE Carotid ultrasound atherosclerosis measurements, including those of the arterial wall and plaque, provide a way to monitor patients at risk of vascular events. Our objective was to examine carotid ultrasound plaque texture measurements and the change in carotid plaque texture during 1 year in patients at risk of events and to compare these with measurements of plaque volu...

Texture is an image having repetition of patterns. There are two types, static and dynamic texture. Static texture is an image having repetitions of patterns in the spatial domain. Dynamic texture is number of frames having repetitions in spatial and temporal domain. This paper introduces a novel method for dynamic texture coding to achieve higher compression ratio of dynamic texture using 2D-m...
