• Abstract: Seed phenotyping is the idea of analyzing the morphometric characteristics of a seed to predict the behavior of the seed in terms of development, tolerance and yield in various environmental conditions. The focus of the work is the application and feasibility analysis of the state-of-the-art object detection and localization neural networks, Mask R-CNN and YOLO (You Only Look Once), for seed phenotyping using Tensorflow. One of the major bottlenecks of such an endeavor is the need for large amounts of training data. While the capture of a multitude of seed images is taunting, the images are also required to be annotated to indicate the boundaries of the seeds on the image and converted to data formats that the neural networks are able to consume. Although tools to manually perform the task of annotation are available for free, the amount of time required is enormous. In order to tackle such a scenario, the idea of domain randomization i.e. the technique of applying models trained on images containing simulated objects to real-world objects, is considered. In addition, transfer learning i.e. the idea of applying the knowledge obtained while solving a problem to a different problem, is used. The networks are trained on pre-trained weights from the popular ImageNet and COCO data sets. As part of the work, experiments with different parameters are conducted on five different seed types namely, canola, rough rice, sorghum, soy, and wheat.

  We employ a contrastive unpaired translation (CUT) generative adversarial network (GAN) to translate indoor plant images to appear as field images. While we train our network to translate an image containing only a single plant, we show that our method is easily extendable to produce multiple-plant field images. We also use our synthetic multi-plant images to train several YoloV5 nano object detection models to perform the task of plant detection.

  In many real-world scenarios of face recognition, the depth of training dataset is shallow, which means only two face images are available for each ID. With the non-uniform increase of samples, such issue is converted to a more general case, a.k.a a long-tail face learning. Based on the Semi-Siamese Training (SST), we introduce an advanced solution, named Multi-Agent Semi-Siamese Training (MASST) MASST includes a probe network and multiple gallery agents, the former aims to encode the probe features, and the latter constitutes a stack of
