In India’s economy, agriculture has been the most significantcontributor. Despite the fact that agriculture’s contribution is decreasing asthe world’s population grows, it continues to be the most important sourceof employment with a little margin of difference. As a result, there is apressing need to pick up the pace in order to achieve competitive, productive,diverse, and long-term agriculture. Plant disease misinterpretations can resultin the incorrect application of pesticides, causing crop harm. As a result,early detection of infections is critical as well as cost-effective for farmers.To diagnose the disease at an earlier stage, appropriate segmentation of thediseased component from the leaf in an accurate manner is critical. However,due to the existence of noise in the digitally captured image, as well asvariations in backdrop, shape, and brightness in sick photographs, effectiverecognition has become a difficult task. Leaf smut, Bacterial blight andBrown spot diseases are segmented and classified using diseased Apple (20),Cercospora (60), Rice (100), Grape (140), and wheat (180) leaf photos in thesuggested work. In addition, a superior segmentation technique for the ROIfrom sick leaves with living backdrop is presented here. Textural features of thesegmented ROI, such as 1st and 2nd order WPCA Features, are discoveredafter segmentation. This comprises 1st order textural features like kurtosis,skewness, mean and variance as well as 2nd procedure textural features likesmoothness, energy, correlation, homogeneity, contrast, and entropy. Finally,the segmented region of interest’s textural features is fed into four differentclassifiers, with the Enhanced Deep Convolutional Neural Network provingto be the most precise, with a 96.1% accuracy. 展开更多

1988—1989年对11个腰果产量性状进行了相关和回归分析研究。腰果产量与成熟腰果数/花序(0.961+)和两性花平均数/花序(0.564+)呈极显著的正相关。腰果平均重量与其长度、宽度和厚度呈显著正相关(0.961+),而与成熟腰果数/花序呈显著负相... 1988—1989年对11个腰果产量性状进行了相关和回归分析研究。腰果产量与成熟腰果数/花序(0.961+)和两性花平均数/花序(0.564+)呈极显著的正相关。腰果平均重量与其长度、宽度和厚度呈显著正相关(0.961+),而与成熟腰果数/花序呈显著负相关。成熟腰果数(b值)对产量的回归系数最大(5.18869)。回归分析表明在11个单独的变异性状中,此一性状是唯一达到显著水平的。 展开更多
