Parallel image quantization using LAN of workstations

Abstract : This report presents the work done to parallelize a quantization algorithm of colorimages on a LAN of workstations. The quantization consists in reducing the number of colors in order to reduce the length of an image. This problem belongs to the NP-complete problems (comparable to the construction of an optimal decision tree). The communications between the different parts of the system have been managed by PVM. One important point is the use of the distributed storage that represents a set of workstations. This distribution allows the complete parallelization of the Read/write operations. Furthermore an interface has been realized to make this parallel algorithm available to any kind of people.
