In this paper, a color correction system is embedded into a multiresolution representation with the goal of reducing the complexity of 3D look-up table transformations. A framework is assumed wherein the image undergoes a multiresolution decomposition, e.g. discrete wavelet transform, for the purpose of image compression or other processing. After the image is reconstructed from its multiresolu...

In this paper, we propose a novel video sequences compression and encryption method combining 3D compressive sensing (3D-CS) with 3D discrete fractional random transform (3D-DFrRT). In this scheme, the original video sequences were transformed with discrete wavelet and measured by three Gaussion random matrices to achieve compression and encryption simultaneously, and then the resulting 3D imag...

As a new scene representation scheme, the concentric mosaic offers a quick way to capture and model a realistic 3D environment. This is achieved by shooting a lot of photos of the scene. Novel views can be rendered by patching vertical slits of the captured shots. The data amount in the concentric mosaic is huge. In this work, we compress the concentric mosaic image array with a 3D wavelet sche...

In this paper, we propose a three-dimensional Set Partitioned Embedded ZeroBlock Coding (3D SPEZBC) lossy-to-lossless compression algorithm for hyperspectral image which is an improved three-dimensional Embedded ZeroBlock Coding (3D EZBC) algorithm. The algorithm adopts the 3D integer wavelet packet transform proposed by Xiong et al. to decorrelate, the set-based partitioning zeroblock coding t...

An efficient motion-compensated 3D wavelet video coding system is proposed in this paper. In this new system, spatio-temporal subbands are generated by MC temporal analysis based on an adaptive GOP structure and 2D spatial wavelet transform, and then encoded by a quadtree-based wavelet image coding method. The experimental results show that, the proposed system can achieve better performance th...

Galaxies are arranged in interconnected walls and filaments forming a cosmic web encompassing huge, nearly empty, regions between the structures. Many statistical methods have been proposed in the past in order to describe the galaxy distribution and discriminate the different cosmological models. We present in this paper results relative to the use of new statistical tools using the 3D isotrop...

This paper proposes a denoising method for accuracy enhancement of 3D (three dimensional) reconstruction process by shadow moiré. The proposed denoising method based on undecimated wavelet transform (UWT) effectively eliminates noise and grating pattern while retaining useful information. The proposed shadow moiré method is compared with structured lighting method which is a common method for 3...
