چکیده

This paper describes how to integrate encryption inn ann al gorithm which uses wavelets to compress data. Wavelets a re more useful inn image compressionn thann other methods. This is be cause the definitionn about which data shouldd be left out is more flexible. This adaptationn of wavelets to specific featur es of images leads to acceptable results. The use of com puters inn image transfer will increase further and it will therefor e become necessary to transfer image data quickly. Inn ad dition, a protection of the image against unauthorizedd access will become nec essary. Image compressionn increases the amount of time needed for transferringg ann image. Regarding the area of telemedic ine, there is a demand for the protection of images. The reason for this demandd is the needd to prevent the relationship bet ween patient data and ann image from beingg determined. The refore, the approachh intends to describe a combinationn of image compres sionn by using wavelets andd to integrate encryption into the wavelet-transform and-compressionn procedure.

High Performance PPMC Compression Algorithm

It has been demonstrated with recent software implementations of context modeling the capability of PPM (Prediction by Partial Matching) [1] type of algorithms to achieve very high compression rates. However, the cost is high in terms of computational complexity and low speed. Hardware implementations of compression algorithms are capable of increasing compression speed by at least an order of ...

Efficient Compression from Non-ergodic Sources with Genetic Algorithms

Several lossless data compression schemes have been proposed over the past years. Since Shannon developed information theory in his seminal paper, however, the problem of data compression has hinged (even though not always explicitly) on the consideration of an ergodic source. In dealing with such sources one has to cope with the problem of defining a priori the minimum sized symbol. The design...

Protective Effect of Encapsulated Nanocurcumin- PEGOA against Oxidative Damage on Human Mesenchymal Stem Cells Exposed to Hydroquinone as a Risk Factor for Leukemia

Introduction: Benzene a well-known environmental pollutant is a human carcinogen which is involved in the manifestation of a number of malignancies. Activation of benzene and its reactive metabolites such as hydroquinone (HQ) leads to continuous production of reactive oxygen species (ROS), causing oxidative Stress. Curcumin, the yellow pigment of curcuma longa, has been shown to possess antioxi...
