报告题目：Computer Vision based Heart Rate Estimation using Facial Videos
报告人：Prof. Umapada Pal (IAPR Fellow)
摘要：Heart Rate (HR) estimation using computer vision techniques in adverse situations, such as arbitrary face movements, complex backgrounds, occlusion, color changes, lighting effects, etc. is challenging for the video technology community. Unlike state-of-the-art models that use color and spatial-temporal information, the present work exploits vital information in multiple domains, namely, spatial-temporal and frequency-temporal using wavelet transform for heart rate estimation. To achieve this, we explore pyramidal structure to extract invariant features to the above-mentioned challenges from spatial-temporal-frequency domains. This work introduces a transformer to derive context information from multiple domains. Furthermore, to strengthen the features, the proposed model introduces a new attention approach called Mutual-Sharing-Multiple Domains (MSMD) to exchange context information across domains in an end-to-end fashion and it will be discussed in this talk. Experimental results on four standard datasets, namely UBFC-rPPG, VIPL-HR, OBF, and MMSE-HR show that the proposed model is generic and invariant to the aforementioned challenges. Furthermore, comparative studies demonstrate that our method is better in terms of MSE and SD measures. Some demonstrations will also be shown to the participants for better understanding.
