Our approach performs comparably with deep learning (DL) methods on "in-the-wild" data that have inexact ground truth, and better than DL methods on more controlled data with exact ground truth. Since our formulation does not require any learning, it enjoys a versatility that allows it to operate with multiple frames of arbitrary sizes. This study's results encourage further research on 3DMM fitting with inequality-constrained optimization methods, which have been unexplored compared to unconstrained methods. Physical function impairment can cause great stress to older adults. The purpose of the study is to investigate the association between self-reported and directly-observed physical function on perceived stress among U.S. Chinese older adults. Data were from the Population Study of Chinese Elderly in Chicago (PINE) of 3,157 Chinese older adults who were 60 and above in the Greater Chicago Area. Self-reported and directly-observed physical function measures, and Perceived Stress Scale were used. Participants had a mean age of 72.8 ± 8.3 years old (range 60-105). Higher scores of Katz activities of daily living impairments (odds ratio [OR]=1.77), Lawton instrumental activities of daily living impartments (OR=1.10, <0.01), Rosow-Breslau index of mobility scale (OR=1.39, <0.05), and Nagi index of basic physical activities scale (OR=1.19, <0.001) were associated with higher levels of perceived stress. In addition, higher scores of directly-observed physical function measurements, including chair stand (OR=0.93), tandem stand (OR=0.71, <0.05), timed walk (OR=0.73, <0.001), and the overall measurement (OR= 0.87, <0.01) were associated with lower level of perceived stress. Findings suggested that poor physical function was associated with perceived stress among U.S. Chinese older adults. Longitudinal studies a
