【摘要】 当前,大部分农作物病害图像识别方法主要关注于精度而忽略了鲁棒性.在面向实际环境时,由于噪声干扰和环境因素影响导致识别精度不高.为此提出了一种高阶残差和参数共享反馈的卷积神经网络模型以应用于实际环境农作物病害识别.其中,高阶残差子网络为病害表观提供丰富细致的特征表达,以提高模型识别精度;参数共享反馈子网络用来进一步抑制原深层特征中的背景噪声,以提高模型的鲁棒性.实验结果表明,当面向实际环境农作物病害识别时,本文方法在识别精度和鲁棒性上均优于其他方法.更多还原

【Abstract】 Most of current crop-disease recognition approaches mainly focus on improving the recognition accuracy on public datasets,while ignoring the recognition robustness.When dealing with real-world recognition problem,the actual recognition accuracy of those approach are often unsatisfactory because of noise interference and environmental influence.To address these issues,we propose a high-order residual and parameter-sharing feedback convolutional neural network(HORPSF) for crop-disease recognition.The high-order residual subnetwork is helpful for improving the recognition accuracy of crop disease.The parameter-sharing feedback subnetwork can effectively depress the background noises and enhance the robustness of the model.Extensive experiment results demonstrate that the proposed HORPSF approach significantly outperforms other competing methods in terms of recognition accuracy and robustness,especially demonstrating superior performance when dealing with the real-world examples of crop-disease recognition.更多还原
