Any quantization introduces errors. An important question is how to suppress their visual effect. In this paper we present a new quantization method for the geometry of 3D meshes, which enables aggressive quantization without significant loss of visual quality. Conventionally, quantization is applied directly to the 3-space coordinates. This form of quantization introduces high-frequency errors...

Quantization naturally exposes knobs in hardware to trade fidelity for efficiency: the more bits that are used to represent the data, the higher the storage and computation overheads. With the emergence of approximate computing research, we set out to answer the following question: how effective is quantization in trading off quality for efficiency, and how does it compare with other approximat...

Quantization, which maps real values of raw data to a series of fixed gray levels, is an inevitable step in Optical Coherence Tomography (OCT) image formation. Three new quantization methods, Minimum Distortion, Information Expansion and Maximum Entropy are applied in the specific problem. Quantization results of a capillary with milk and the femoralis of rabbit are shown in this paper. Compari...

In the given paper a method of the parameter quantization in speech coder on basis of human auditory model is presented. Output speech parameters of the coder are three sinusoidal parameters: amplitude, frequency and phase. For amplitude and frequency quantization we propose to use a vector quantization, and for phases – scalar quantization. This parameter quantization method allows to achieve ...

The connection between four different approaches to quantization of the relativistic particle is studied: reduced phase space quantization, Dirac quantization, BRST quantization, and (BRST)-Fock quantization are each carried out. The connection to the BFV path integral in phase space is provided. In particular, it is concluded that that the full range of the lapse should be used in such path in...
