Abstract

The invention provides a method for identifying a mechanical damage area of a corn ear. The method comprises the following steps of: S1, dividing a corn ear image into image patches, obtaining a cornear image patch data set; S2, according to the normalized feature of each image patch in the image patch data set, determining a candidate region patch by using a support vector machine; and S3, usinga convolutional neural network model to determine the mechanical damage region in the candidate region patches. According to the method for identifying the mechanical damage area of the corn ear, selecting the candidate region in the corn ear image by using the support vector machine, further identifying by the convolutional neural network model, and can quickly and accurately identify the mechanical damage region of the corn ear; therefor, the speed and accuracy of the identification of the mechanical damage area of the corn ear can be improved, and the needs of corn testing can be meet.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, and more particularly, relates to a method for recognizing a mechanically damaged region of corn ears. Background technique [0002] At present, the identification of mechanically damaged areas of corn ears is the basic project in the detection of corn ear defects. Maize ears will inevitably be mechanically damaged during mechanical harvesting and transportation. Manually judging the mechanical damage of corn ears is a heavy workload and difficult to quantify. Generally, only the classification of mechanical damage can be given. [0003] The use of computer vision to identify the mechanically damaged area of ​​corn ears can well replace manual labor and effectively improve the identification efficiency. The main problem of automatic recognition of mechanically damaged areas in corn ear images based on machine learning is that they are easily affected by light, and high light areas ar...
