As Contourlet transform can give an asymptotic representation of edges and contours in image by virtue of its characteristics of multidirectional and flexible, it is introduced into the quality assessment of fused image. A new method (CSSIM) for image fusion quality assessment based on Contourlet and structural similarity of images is put forward in this paper. We introduce distortion channel to simulate...
The strategies for the preservation of historical documents can include their digitization, which is an effective way to make them publicly available while preventing degradation of the original sources. The Arquivo Publico Mineiro (APM), the Archives of the State of Minas Gerais, has a collection of historical photographs from Brazil, and some of them have been digitized. The availability of digital...
In order to ease the motion boundary in temporal-domain algorithms, the paper propose to utilize the luminance of macro-block(MB) around the lost MB, to obtain a more precise and dense motion vectors, the rational function be used in motion vector interpolation. Mutation points in the vector field are detected, as a combination of movement of the border, in the same way, the missing pieces of motion...
To make a spectral representation of color practicable for volume rendering, a new low-dimensional subspace method is used to act as the carrier of spectral information. With that model, spectral light material interaction can be integrated into existing volume rendering methods at almost no penalty. In addition, slow rendering methods can profit from the new technique of postillumination-generating...
This paper demonstrates a software and hardware implementation for creating and visualising a three dimensional voxel based model for any arbitrary polynomial function. Preliminary results demonstrate its use from the model creation, within a cluster computing engine, to a large real-time visualisation system via a small PC rendering farm, have been carried out. This includes the choice of data representation...
