3.2. Data Acquisition

The images used in this paper were captured at the Ya’an kiwifruit plantation in Dujiangyan, Sichuan Province, China. A Canon EOS60D DSLR camera with a resolution of 1920 × 1080 pixels was utilized to capture the dataset. After removing the redundant background via data processing techniques such as center cropping, we obtained a high-quality 520 × 520-pixel kiwifruit trunk disease dataset. The initial few-shot dataset consisted of 128 images, which laid the foundation for the subsequent experiments and analysis.
