Key-Point Sequence Lossless Compression for Intelligent Video Analysis

Lossless compression of video sequences

In this paper we investigate lossless compression schemes for video sequences A simple adaptive prediction scheme is presented that exploits temporal correlations or spectral correlations in addition to spatial correlations It is seen that even with motion compensation schemes that utilize only temporal correlations do not perform signif icantly better than schemes that utilize only spectral co...

Lossless Compression of Video Using Motion Compensation

Lossless Compression of Floating-Point Geometry

The geometric data sets found in scientific and industrial applications are often very detailed. Storing them using standard uncompressed formats results in large files that are expensive to store and slow to load and transmit. Many efficient mesh compression techniques have been proposed, but scientists and engineers often refrain from using them because they modify the mesh data. While connec...

Lossless compression of predicted floating-point geometry

The size of geometric data sets in scientific and industrial applications is constantly increasing. Storing surface or volume meshes in standard uncompressed formats results in large files that are expensive to store and slow to load and transmit. Scientists and engineers often refrain from using mesh compression because currently available schemes modify the mesh data. While connectivity is en...

Intelligent and Lossless Data Compression for Arabic Documents

Information is the very most precious good in computer usage. Cleverly combined, and well kept, it allows a maximum profit from a computer. Unfortunately, it seems be in the nature of things that information becomes quickly very voluminous. In addition, available space memory seems always insufficient. We noted, also, an increase in the number of users and the time of use. Consequently, new pro...
