However, the biggest problem is that phenotypic data is not enough to support extensive data analysis. Rivendell inhabitants Crossword Clue LA Times. 9 applied the threshold method, area marker method, and Freeman link code method to diagnose five major diseases of maize foliage with an accuracy of more than 80%. All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers. The loss function we used is MSEloss that measures the mean squared error (squared L2 norm) between each element in the input and target. Conversely, models with short time consumption do not have high recognition rates. Recovering hyperspectral images from RGB images is an ill-posed problem, since a large amount of information is lost during the process of integrating the hyperspectral bands into RGB values.
We proposed an effective cascade network for maize disease identification in complex environments, which were composed of a Faster R-CNN leaf detector (denoted as LS-RCNN) and a CNN disease classifier (denoted as CENet). HSI, not like RGB image which only has three spectral bands, has multiple bands could be used for extracting disease characteristics, so it is an ideal candidate for pixel-wise disease detection (Nagasubramanian et al. Li, J., Lin, L., Tian, K. & Alaa, A. Data standardization is mainly to solve the problem of different dimensions of current data indexes.

AUC (Area under Curve) is defined as the area enclosed by the coordinate axis under the ROC curve. The disease is obviously affected by the climate, and it is easy to occur in weather conditions with many rainy days, high air humidity, and poor light. For example, the dataset collected by [7] is small, and the most important crop phenotypic data in suitability evaluation is only 6 kinds, which is seriously insufficient. Empty Stalk Rate (ESR). 06297; the accuracy of the original dataset is relatively lower, with the highest accuracy of 94. To alleviate this contradiction, we need to actively explore the relationship between climate change and crop variety adaptability and optimize the utilization of land resources. In this way, we can keep the advantages of both RGB image and HSI, it is not only convenient to detect disease accurately but also affordable. This shows that under the same conditions, our model can perform image recognition in complex environments quickly, efficiently, and accurately. Various network structures have been proposed to accomplish the spectral recovery tasks, such as CNN and Generative Adversarial Network (GAN) (Zhang et al. The dense structure enables the lth layer to receive the features from all preceding layers which can efficiently alleviate the problem of gradient vanishing, and what's more, it offers a probability for deeper neural network.
