چکیده

In this paper a contour prediction scheme is presented. Its application in a region-based motion compensation algorithm is shown. To achieve optimal performance in a rate-distortion sense the predicted regions are optimized by using a Lagrangian cost function. By using contour prediction the bit rate for motion compensation can be decreased.

Planelet Transform: A New Geometrical Wavelet for Compression of Kinect-like Depth Images

With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...

Image compression with a hybrid wavelet-fractal coder

A hybrid wavelet-fractal coder (WFC) for image compression is proposed. The WFC uses the fractal contractive mapping to predict the wavelet coefficients of the higher resolution from those of the lower resolution and then encode the prediction residue with a bitplane wavelet coder. The fractal prediction is adaptively applied only to regions where the rate saving offered by fractal prediction j...

A LATTICE VECTOR QUANTIZER FOR GENERALIZED GAUSSIAN SOURCES - Image Processing, 1995. Proceedings., International Conference on

A fixed-rate lattice vector quantizer for generalized Gaussian (GG) sources is presented. By using the contour of counstant probability of a generalized Gaussian source to bound the integer lattice, this vector quantizer in the limit of high dimension achieves optimal boundary gains for GG sources. Low-complexity techniques for rate control, optimal codevector search and enumeration are develop...

Universal successive refinement of CELP speech coders

Many speech coding standards are based upon code-excited linear prediction (CELP), and it is desirable to develop layered coding methods that are compatible with this installed base of coders. We propose a layered speech coding structure that is universally compatible with all CELP-based coders. This structure encodes the reconstruction error signal from layer 1 using a lowdelay, adaptive tree ...

A very low bit rate speech coder based on a recognition/synthesis paradigm

Recent studies have shown that a concatenative speech synthesis system with a large database produces more natural sounding speech. We apply this paradigm to the design of improved very low bit rate speech coders (sub 1000 b/s). The proposed speech coder consists of unit selection, prosody coding, prosody modification and waveform concatenation. The encoder selects the best unit sequence from a...
