Background-Aware Domain Adaptation for Plant Counting

Min Shi, Xing-Yi Li, Hao Lu, Zhi-Guo Cao
2022 Frontiers in Plant Science  
This problem setting is also called unsupervised domain adaptation (UDA). Despite UDA has been a long-standing topic in machine learning society, UDA methods are less studied for plant counting.  ...  Deep learning-based object counting models have recently been considered preferable choices for plant counting.  ...  For image-level domain adaptaion methods (FDA and PCEDA), domain adaptation is achieved by aligning the image styles. We visualize the transferred images in Figure 10 .  ...
