Adaptive Greedy Frame Selection for Long Video Understanding
Yuning Huang, Xiaoyu Ji, Joseph Huang +2
Large vision--language models (VLMs) are increasingly applied to long-video question answering, yet inference is often bottlenecked by the number of input frames and resulting visu…
Instance camera focus prediction for crystal agglomeration classification
Xiaoyu Ji, Chenhao Zhang, Tyler James Downard +3
Agglomeration refers to the process of crystal clustering due to interparticle forces. Crystal agglomeration analysis from microscopic images is challenging due to the inherent lim…
Denoising of Two-Phase Optically Sectioned Structured Illumination Reconstructions Using Encoder-Decoder Networks
Allison Davis, Yezhi Shen, Xiaoyu Ji +1
Structured illumination (SI) enhances image resolution and contrast by projecting patterned light onto a sample. In two-phase optical-sectioning SI (OS-SI), reduced acquisition tim…
Confidence-aware agglomeration classification and segmentation of 2D microscopic food crystal images
Xiaoyu Ji, Ali Shakouri, Fengqing Zhu
Food crystal agglomeration is a phenomenon occurs during crystallization which traps water between crystals and affects food product quality. Manual annotation of agglomeration in…
Empowering Manufacturers with Privacy-Preserving AI Tools: A Case Study in Privacy-Preserving Machine Learning to Solve Real-World Problems
Xiaoyu Ji, Jessica Shorland, Joshua Shank +4
Small- and medium-sized manufacturers need innovative data tools but, because of competition and privacy concerns, often do not want to share their proprietary data with researcher…
