We review the principles of the classification method and we evaluate its hardware implementation cost in terms of FPGA s slice using different weak classifiers based on the general concept of hyperrectangle. The main novelty of our approach is that the tool allows the user to find automatically an appropriate tradeoff between classification performances and hardware implementation cost and that the generated architecture is optimized for each training process. We present results obtained using Gaussian distributions and examples from UCI databases. Finally we present an example of industrial application of real-time textured image segmentation. Keywords and phrases Adaboost FPGA classification hardware image segmentation. 1. INTRODUCTION In this paper we propose a method of automatic generation of hardware implementation of a particular decision rule. This paper focuses mainly on .
