[0123] refer to Figure 1 to Figure 10 , Table 1 to Table 4, the image recognition method based on multi-column convolutional neural network fuzzy evaluation, the steps are as follows:

[0124] (1) From the standard GTSRB (German Traffic Sign Recognition Benchmark) data set, randomly select 5000 images collected in the real environment, with low resolution, different light intensity, partial occlusion, angle of view tilt, motion blur and other images that are not conducive to classification, and perform Binarization, histogram equalization, adaptive histogram equalization, image adjustment, morphological processing, such as Figure 1-Figure 10 shown.

[0125] (2) Input the image of file 1 into a multi-column convolutional neural network for training to obtain the final network structure and parameters, and input test data that is not repeated with the training set. The recognition effect of each column of convolutional neural network is shown in Table 3. Show.

Abstract

The invention relates to an image recognition method based on multi-column convolutional neural network fuzzy evaluation. By combining an image preprocessing technology, a convolutional neural network and a fuzzy mathematical method, interference information in an image sample acquired in the real environment is overcome by adopting different preprocessing technologies from different perspectives respectively, feature information beneficial to recognition is strengthened, the preprocessed image is input to the preprocessed and optimized multi-column convolutional neural networks having different structures respectively, then fuzzy evaluation based on comprehensive affiliation degree and discrete affiliation degree is performed on the output results of the multi-column convolutional neural networks by adopting a fuzzy matrix to determine a fuzzy evaluation manner suitable for the image, and a recognition result is finally accurately obtained.

Description

Technical field: [0001] The invention relates to an image recognition method with interference and deformation, in particular to an image recognition method based on fuzzy evaluation of a multi-column convolutional neural network. Background technique: [0002] The continuous development of computer technology and information technology has made computer intelligent image recognition technology more and more widely used. Computer intelligent image recognition technology can quickly obtain the required information to help people think and make better decisions. Real-scene image recognition, such as traffic sign recognition, face recognition, fire flame recognition, etc., is of great significance, and it is also more uncertain than printed text recognition due to the change of image acquisition conditions at any time. [0003] The present invention provides an image recognition method based on multi-column deep neural network fuzzy evaluation, which does not require complex f...
