Abstract

Although the performance of 3D human pose and shape estimation methods has improved significantly in recent years, existing approaches typically generate 3D poses defined in camera or human-centered coordinate system. This makes it difficult to estimate a person's pure pose and motion in world coordinate system for a video captured using a moving camera. To address this issue, this paper presents a camera motion agnostic approach for predicting 3D human pose and mesh defined in the world coordinate system. The core idea of the proposed approach is to estimate the difference between two adjacent global poses (i.e., global motion) that is invariant to selecting the coordinate system, instead of the global pose coupled to the camera motion. To this end, we propose a network based on bidirectional gated recurrent units (GRUs) that predicts the global motion sequence from the local pose sequence consisting of relative rotations of joints called global motion regressor (GMR). We use 3DPW and synthetic datasets, which are constructed in a moving-camera environment, for evaluation. We conduct extensive experiments and prove the effectiveness of the proposed method empirically. Code and datasets are available at https://github.com/seonghyunkim1212/GMR

Abstract

This study investigated the affects of cognitive ability, creativity, and self-esteem on kindergartners' problem behaviour. Participants were 203 children (mean age = 65.8 months) attending kindergartens in Korea. Data collection used the Korean version of Child Behaviour Checklist, the Kaufman Assessment Battery for Children, the Torrance Test of Creative Thinking, and the Children's Sense of Self-Esteem Inventory. Pearson's correlations and stepwise multiple regression analysis were used to analyse the data. There were four primary outcomes. First, there were negative correlations between children's problem behaviour (internalising and externalising problems) and cognitive ability. Second, there was a negative correlation between internalising problems and fluency in creativity. No correlation was found between children's externalising problems and creativity. Third, there were negative correlations between children's problem behaviour (internalising and externalising problems) and self-esteem. Fourth, sequential processing, emotional competence, and fluency were revealed to be predictors of children's internalising problems. Social competency and sequential processing were found to be predictors of children's externalising problems.
