Detecting diseases in apple tree leaves using FPN–ISResNet–Faster RCNN
European Journal of Remote Sensing, 2023 Apple leaf diseases typified by small disease spots are generally difficult to detect in images. This study proposes a deep learning model called the feature pyramid networks (FPNs) –inception squeeze-and-excitation ResNet (ISResNet)–Faster RCNN (region ...
