Fusion of multispectral satellite imagery using a cluster of graphics processing unit

The paper presents a parallel implementation of existing image fusion methods on a graphical cluster. Parallel implementations of methods based on discrete wavelet transformation (Haars and Daubechies discrete wavelet transform) are developed. Experiments were performed on a cluster using GPU and CPU and performance gains were estimated for the use of the developed parallel implementations to process satellite images from satellite Landsat 7. The implementation on a graphic cluster provides performance improvement from 2 to 18 times. The quality of the considered methods was evaluated by ERGAS and QNR metrics. The results show performance gains and retaining of quality with the cluster of GPU compared to the results obtained by the authors and other researchers for a CPU and single GPU.

Generalized 3D Voxel Image Synthesis Architecture for Volumetric Spatial Visualization

A general concept of 3D volumetric visualization systems is described based on 3D discrete voxel scenes (worlds) representation. Definitions of 3D discrete voxel scene (world) basic elements and main steps of the image synthesis algorithm are formulated. An algorithm for solving the problem of the voxelized world 3D image synthesis, intended for the systems of volumetric spatial visualization, is proposed. A computer-based architecture for 3D volumetric visualization of 3D discrete voxel world is presented. On the basis of the proposed overall concept of discrete voxel representation, the proposed architecture successfully adapts the ray tracing technique for the synthesis of 3D volumetric images. Since it is algorithmically simple and effectively supports parallelism, it can efficiently be implemented. Key words:Volumetric spatial visualization, 3D volumetric imagesynthesis, discrete voxel world, ray tracing.
