Modeling Camera Effects to Improve Visual Learning from Synthetic Data

Recent work has focused on generating synthetic imagery to increase the size and variability of training data for learning visual tasks in urban scenes. This includes increasing the occurrence of occlusions or varying environmental and weather effects. However, few have addressed modeling variation in the sensor domain. Sensor effects can degrade real images, limiting generalizability of network performance on visual tasks trained on synthetic data and tested in real environments. This paper proposes an efficient, automatic, physically-based augmentation pipeline to vary sensor effects --chromatic aberration, blur, exposure, noise, and color cast-- for synthetic imagery. In particular, this paper illustrates that augmenting synthetic training datasets with the proposed pipeline reduces the domain gap between synthetic and real domains for the task of object detection in urban driving scenes

Examining the Effects of Exposure to Nature on Well-Being: Implications for College Campuses

Humans attraction to the natural environment stems from our evolutionary tendencies. Biophilia is defined by E.O. Wilson as the “innate tendency to focus on life and lifelike processes (Wilson, 1984, p. 1).” Recent studies have shown that spending time outside in nature is beneficial to physical and mental health as well as well-being. Nature is filled with intriguing things such as animals, plants, fresh air and other aspects which can help an individual replenish. Some of these benefits include stress reduction, opportunities and motivation to complete tasks. Research indicates that adults who work in offices would perform better if they had views of natural landscape painting or even a window which faced nature. This paper will provide a review of research on how nature affects human well-being and mental health. The findings in this paper can be beneficial to college students and those assisting them in a number of ways. Based on the available research literature, this paper concludes with a set of recommendations of how attention to the influence of nature can enhance the quality of campus life and the literature. As mostly young individuals transitioning into the adult world, it would help influence their well-being in a positive way that will promote creativity and motivation

User quality of experience of mulsemedia applications

User Quality of Experience (QoE) is of fundamental importance in multimedia applications and has been extensively studied for decades. However, user QoE in the context of the emerging multiple-sensorial media (mulsemedia) services, which involve different media components than the traditional multimedia applications, have not been comprehensively studied. This article presents the results of subjective tests which have investigated user perception of mulsemedia content. In particular, the impact of intensity of certain mulsemedia components including haptic and airflow on user-perceived experience are studied. Results demonstrate that by making use of mulsemedia the overall user enjoyment levels increased by up to 77%
