Automated image generation via prompt-based guidance
Developed a fully automated user-driven T2I framework using prompt engineering; discovered major limitations in diffusion-based models for complex object generation. Introduced a novel CAS metric and achieved visual flaw detection accuracy by nearly 240% (0.54 vs. 0.16) over the CLIP baseline across four vehicle categories.
