    摘要:

    針對自然背景下牧草難識別的問題,,提出一種基于雙池化與多尺度核特征加權的卷積神經網絡牧草識別方法,。雙池化特征加權結構通過將卷積層輸出的特征圖分別進行最大值池化和均值池化得到兩組特征圖,,引入特征重標定策略,依照各通道特征圖對當前任務的重要程度進行加權,,以增強有用特征,、抑制無用特征;多尺度核特征加權結構通過在卷積層中同時使用3×3和5×5兩種卷積核,,并將網絡的前幾層特征復用后進行加權,,以提高重要特征的利用率。對10類牧草圖像進行識別實驗,,結果表明,,該方法識別率為94.1%,比VGG-13網絡提高了5.7個百分點,,雙池化與多尺度特征加權有效提高了牧草識別精度,。

    Abstract:

    In order to solve the problem of forage recognition under natural conditions, a convolutional neural network method based on double-pooling feature weighting and multi-scale convolution kernel feature weighting structure was proposed. The spatial information and significance information of the image were fully utilized by using the dual-pooling feature weighted structure. Two groups of feature graphs were obtained by max-pooling and mean-pooling of feature graphs output from the convolution layer, and then these two groups of features were spliced. Finally, a feature re-calibration strategy was introduced to weight the importance of current tasks according to the feature graphs of each channel, so as to enhance useful features and suppress useless features. Image information was more fully mined by using multi-scale feature weighting structure. The 3×3 and 5×5 convolution kernels were used at the same time, and the features of the first several layers of the network were spliced with the features of the current layer to improve feature utilization rate. Feature re-calibration strategy was also introduced to weight features. The recognition experiments of ten pasture images showed that the recognition rate of the method was 94.1%, which was 5.7 percentage points higher than that of VGG-13 network, the double pooling and multi-scale feature weighting structure effectively improved the recognition accuracy.
