Speeding up structure from motion on large scenes using parallelizable partitions
Structure from motion based 3D reconstruction takes a lot of time for large scenes which consist of thousands of input images. We propose a method that speeds up the reconstruction of large scenes by partitioning it into smaller scenes, and then recombining those. The main benefit here is that each subscene can be optimized in parallel. We present a widely usable subdivision method, and show that the difference between the result after partitioning and recombination, and the state of the art structure from motion reconstruction on the entire scene, is negligible

Introduction: spiritual landscapes of Southeast Asia
This Introduction foreshadows the main themes of this special issue on spiritual landscapes of Southeast Asia. Throughout Southeast Asia, links exist between spirit beings or potent energies and particular sites in the landscape, including trees, mountains and rivers. These are highlighted in this collection of papers via the notion of 'spiritual landscapes'. This concept also broadens anthropological approaches to the religious significance of the landscape, by problematising the separation of 'natural' and 'cultural' environments while sidestepping the implication that something called 'sacred geography' can be separated from the pragmatic activities of daily life. Following an ethnographic overview of spirit-places and environmental forces in the region, I discuss our need to take more seriously the claims of many Southeast Asian people that their landscapes have agency. In the context of religious conversion, the agency of the landscape often becomes a central concern, as reformers and missionaries seek to 'purify' the environment of such spiritual power. However, in addition to 'purification', ongoing conversion may also involve new forms of conversation with the landscape, including re-enchantments, religious syntheses or reassertions of the landscape's potency

The 2019 Conference on Health and Active Transportation: Research Needs and Opportunities.
Active transportation (AT) is widely viewed as an important target for increasing participation in aerobic physical activity and improving health, while simultaneously addressing pollution and climate change through reductions in motor vehicular emissions. In recent years, progress in increasing AT has stalled in some countries and, furthermore, the coronavirus (COVID-19) pandemic has created new AT opportunities while also exposing the barriers and health inequities related to AT for some populations. This paper describes the results of the December 2019 Conference on Health and Active Transportation (CHAT) which brought together leaders from the transportation and health disciplines. Attendees charted a course for the future around three themes: Reflecting on Innovative Practices, Building Strategic Institutional Relationships, and Identifying Research Needs and Opportunities. This paper focuses on conclusions of the Research Needs and Opportunities theme. We present a conceptual model derived from the conference sessions that considers how economic and systems analysis, evaluation of emerging technologies and policies, efforts to address inclusivity, disparities and equity along with renewed attention to messaging and communication could contribute to overcoming barriers to development and use of AT infrastructure. Specific research gaps concerning these themes are presented. We further discuss the relevance of these themes considering the pandemic. Renewed efforts at research, dissemination and implementation are needed to achieve the potential health and environmental benefits of AT and to preserve positive changes associated with the pandemic while mitigating negative ones
