“…After the above analysis, a total of 10 vegetation indices, namely, PRI, PSRI, MSR, NDVI, ARI, SIPI, mND705, SRred−edge, CIred−edge, and GI, were selected as the final input features of the model to complete early and mid-term winter wheat stripe rust detection. The physicochemical parameters of the leaf cell internal structure, chlorophyll, anthocyanin, and moisture are all changed after the wheat is infested by stripe rust [4,8,9,26]. The SIPI, PRI, and PSRI were all changed with factors, such as pigment content and photosynthetic rate in green vegetation [8,12].…”
