【Objective】 Texture detection and grading of dried Hami jujube is a difficult problem to realize the automatic classification of the dried date appearance quality, therefore, a method of texture classification of Hami jujube based on convolutional neural network was proposed.【Method】In this method, color images of uniform size were input into the network, and the convolutional kernel automatically extracted its texture features, and then classified them.【Result】Experimental results showed that the CNN could solve the problem of texture classification of Hami dried jujube, and the accuracy rate of the classification was up to 97.7%.【Conclusion】Compared with the commonly used gray level co-occurrence matrix(GLCM) to extract the texture characteristics(maximum probability, correlation, contrast, energy, homogeneity and entropy) of Hami dried jujube, and then compared with the accuracy classified by BP neural network(BP) and aupport vector machines(SVM), this method avoided complicated texture extraction and image preprocessing, and the recognition rate was higher when the test time was similar.
