Homemade Cloth Face Masks Identification in Indonesia

Hyper-realistic face masks: a new challenge in person identification

We often identify people using face images. This is true in occupational settings such as passport control as well as in everyday social environments. Mapping between images and identities assumes that facial appearance is stable within certain bounds. For example, a person's apparent age, gender and ethnicity change slowly, if at all. It also assumes that deliberate changes beyond these bounds...

A cluster randomised trial of cloth masks compared with medical masks in healthcare workers

Evolutionary identification of cloth animation models

This paper presents an application of evolutionary genetic techniques to the identification of internal parameters of a mass-spring physically-based animation model. A physical model of fabrics is first presented. It uses a mass-spring mesh and an inverse dynamics procedure in order to model the non-linear elasticity of fabrics. A method to identify the internal parameters of the model from geo...
