Problems solved by technology

[0002] At present, computer software usually uses standard OCR (Optical Character Recognition) or templates for matching when performing character recognition. These solutions can only handle standard characters, and need to provide a large number of sample library files. and distorted characters, which makes it very difficult for the existing technology to recognize special characters such as deformed characters or handwritten characters, and lacks accuracy

Embodiment Construction

[0048] In order to make the objects and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0049] The embodiment of the present invention provides a pattern recognition method, including the following steps:

[0050] S1. Input the image to be recognized;

[0051] S2. Divide the input to-be-recognized image into x area blocks according to the Unicom component, where x is a positive integer. If x is equal to the number of characters contained in the image, perform S3, and if x is less than the number of characters contained in the image, then After dividing the x area blocks into several area blocks according to the horizontal projection, perform S3;

[0052] S3. Convert each pixel in the area block into log-polar coordinate...

Abstract

The invention discloses a pattern recognition method and system. The pattern recognition method includes following steps: segmenting an input to-be-recognized image into a plurality of region blocks according to connected components, respectively converting each pixel point in the region blocks into a logarithm polar coordinate, respectively converting each logarithm polar coordinate into a one-dimensional matrix, and calculating a filter of a first layer kernel principal component analysis network and training output images of the first layer kernel principal component analysis network; obtaining a local feature matrix of the training output images of the first layer kernel principal component analysis network, and calculating a filter of a second layer kernel principal component analysis network and training output images of the second layer kernel principal component analysis network; and performing binarization on each image in the training output images of the second layer kernel principal component analysis network, calculating the image similarity of an obtained binary image and each image in an image library, and outputting a recognition result. According to the method and system, the accuracy rate of character recognition is increased, and the recognition accuracy is improved.

Description

technical field [0001] The invention relates to an image recognition method, in particular to a pattern recognition method and system. Background technique [0002] At present, computer software usually uses standard OCR (Optical Character Recognition) or template matching when performing character recognition. These schemes can only process standard characters, and need to provide a large number of sample library files, which cannot be used for scaling, rotation, and overlapping. It is difficult to recognize special characters such as deformed characters or handwritten characters in the prior art, and it lacks accuracy. SUMMARY OF THE INVENTION [0003] To solve the above problems, the present invention provides a pattern recognition method and system. [0004] To achieve the above object, the technical scheme adopted in the present invention is: [0005] The pattern recognition method includes the following steps: [0006] S1. Input the image to be recognized; [000...
