Abstract

Medical images present specific characteristics which require to be exploited by an explicit and efficient compression algorithm. The Vector Quantization (VQ) constitutes a crucial stage in lossless Digital images compression where it allows to create a dictionary on the level "block" by a neuronal approach that of Kohonen (Self Organizing Map : SOM) which is widely used in implementation of FPGA circuits for medical image compression
applications. This paper is devoted to the implementation of a new combined method based on wavelet transform and neurons network (WT-SOM) and designed for the implementation on FPGA for medical images compression applications. Simulation results show the effectiveness of our proposed method.
