Probabilistic Based Rock Texture Classification
The classification of natural images is an essential task in computer vision and pattern recognition applications. Rock images are the typical example of natural images, and their analysis is of major importance in rock industries and bedrock investigations. Rocks are mainly classified into three types. They are Igneous, Metamorphic and Sedimentary. They are further classified into Andesite, Ba...
متن کاملDetermination of Damage Constitutive Behavior for Rock Salt Under Uniaxial Compression Condition with Acoustic Emission
The mechanical characteristics of rock salt have an important influence on the safety of the salt cavity. The acoustic emission (AE) technique was used to analyze the generation of microcracks in rock salt under uniaxial compression condition. By monitoring acoustic emission in whole process of stress strain curve under uniaxial compression test, the damage characteristic of rock salt is obtain...
متن کاملLocally-Adaptive Texture Compression
Current schemes for texture compression fail to exploit spatial coherence in an adaptive manner due to the strict efficiency constraints imposed by GPU-based, fragment-level decompression. In this paper we present a texture compression framework for quasi-lossless, locally-adaptive compression of graphics data. Key elements include a Hilbert scan to maximize spatial coherence, efficient encodin...
متن کاملContent Aware Texture Compression
Efficient and high quality texture compression is important because computational powers are always limited, especially for embedded systems such as mobile phones. To access random texels instantly, down sampling and S3TC are the most commonly used methods due to the fixed compression ratio at every local region. However, the methods are content oblivious, which uniformly discard texel informat...
متن کاملHierarchical texture compression
Texture mapping is a technique for adding visual realism to the computer generated images. As the level of realism increases with the number and the resolution of textures, we are faced with the problem of limited texture memory space. Moreover, in order to alleviate the aliasing artefacts many graphics systems use the mipmapping technique which needs to store additionally the texture pyramid. ...
