I used bounding box annotation to identify and label people within images, including isolating individuals from group scenes for separate image generation tasks. I also annotated interactive elements on websites by selecting all components a user could engage with, supporting UI-focused datasets. Additionally, I labeled clothing items within images and conducted visual searches to accurately classify and match them with relevant categories.
