ImageText Generation
In my role as an Advanced AI Trainer at Invisible Technologies, I worked on the Hawkeye project, which focused on image annotation and visual data labeling for AI model training. This involved analyzing a wide range of images, including indoor, outdoor, and complex scenes, and providing detailed, structured descriptions capturing all visible elements. I was responsible for identifying objects, entities, and contextual details within each image to improve model understanding of visual data. Additionally, I performed content moderation by flagging inappropriate or sensitive material according to predefined guidelines. This experience strengthened my skills in image analysis, data annotation, quality control, and working with multimodal AI systems, contributing to the development of more accurate and reliable machine learning models.
