Hand-written font recognition method based on two-dimensional convolution dimension reduction

Abstract

The invention provides a hand-written font recognition method based on two-dimensional convolution dimension reduction, for solving the problem that in some complicated situations, such as high deformation, a current handwritten recognition algorithm is not well in high-dimensional data effect. The hand-written font recognition method based on two-dimensional convolution dimension reduction includes the steps: obtaining a special convolutional neural network by adding an optimization layer, so as to enable the network to be able to perform recognition and dimension reduction at the same time;designing a new linear determination analysis target function to reduce the complexity of the optimization process, and lowering the information dimension utilized by the network during the process ofrecognizing complex fonts and simplifying recognition by optimizing the function; and finally recognizing the hand-written font images by means of the trained network, to obtain the recognition result. As the hand-written font recognition method based on two-dimensional convolution dimension reduction uses the specially designed convolutional neural network to optimize the new linear determination analysis target function, and can obtain better recognition performance.
