Improving the quality of optical character recognition method by joint application of wavelet- and curvelet-transforms and vocabulary search algorithm
Optical character recognition is a complex problem, which has no definite solution. There are a lot of approaches and methods to solve this problem. The proposed approach, based on aggregate usage of wavelet-transformation for reducing the feature space and probabilistic neural network for classific...
