Continuous spatiotemporal analysis of keyhole morphological evolution extracted via the tracking-by-detection framework. (a) A tracked keyhole feature with localized dimensional axes superimposed to illustrate geometric property extraction. (b-1 to b-4) Time-resolved quantitative profiles of the extracted geometric parameters across nearly 200 consecutive frames, detailing the high-frequency fluctuations in keyhole width, height, aspect ratio, and total area. This continuous, structured data output forms the basis for subsequent LLM-driven statistical synthesis.
