The problem of image compression using the PWL (Periodic Walsh Piecewise-Linear) transform and optimal scalar quantization of PWL spectrum has been presented in the paper. Short description of the PWL transform has been included. Optimal Lloyd-Max Quantization has also been presented. The procedure of the presented compression method is based on quantization of class of scalar variables representing blocks of the image. Effectiveness of the compression method has been examined. Visual representation of the results of investigation has been included.
