Rhythm-Structured Predictive Learning for Remote Photoplethysmography
Ba-Thinh Nguyen, Huu-Dung Nguyen, Thi-Duyen Ngo +1
Remote photoplethysmography (rPPG) estimates physiological signals from facial videos by analyzing subtle pulse induced skin color variations. Despite recent progress, existing sel…
VisAnalog: A Diagnostic Suite for Visual Concept Transfer on Natural Images
Zhaonan Li, Kyle R. Chickering, Bangzheng Li +13
A useful test of visual concept learning is not just whether a model can recognize a concept in a single image, but whether it can preserve and manipulate concept-level properties…
BTS-rPPG: Orthogonal Butterfly Temporal Shifting for Remote Photoplethysmography
Ba-Thinh Nguyen, Thi-Duyen Ngo, Thanh-Trung Huynh +2
Remote photoplethysmography (rPPG) enables contactless physiological sensing from facial videos by analyzing subtle appearance variations induced by blood circulation. However, mod…
HOT: Harmonic-Constrained Optimal Transport for Remote Photoplethysmography Domain Adaptation
Ba-Thinh Nguyen, Thi-Duyen Ngo, Thanh-Trung Huynh +2
Remote photoplethysmography (rPPG) enables non-contact physiological measurement from facial videos; however, its practical deployment is often hindered by substantial performance…
Improved Object-Centric Diffusion Learning with Registers and Contrastive Alignment
Bac Nguyen, Yuhta Takida, Naoki Murata +4
Slot Attention (SA) with pretrained diffusion models has recently shown promise for object-centric learning (OCL), but suffers from slot entanglement and weak alignment between obj…
G2D2: Gradient-Guided Discrete Diffusion for Inverse Problem Solving
Naoki Murata, Chieh-Hsin Lai, Yuhta Takida +4
Recent literature has effectively leveraged diffusion models trained on continuous variables as priors for solving inverse problems. Notably, discrete diffusion models with discret…
