Lecture 12. Filter optimization by supervised and unsupervised learning Supervised learning method using layered neural network — The weighted median filter is expressed by the layered neural network, if the input and output are binarized by the threshold decomposition. — The optimum weight coefficients are obtained by the optimized weight coefficients of the layered neural network by the supervised learning. An example pair of an input noisy image and its ideal output is offered to the learning procedure. — Similar methods are applied to cascades of filters using the multilayer network and the error back propagation algorithm
