Chapter
Low-light is a challenging environment for both human and computer vision to perform tasks such as object classification and detection. Recent works have shown potential in employing enhancements algorithms to support and improve such tasks in low-light, however there has not been any focused analysis to understand the direct effects that low-light...
Conference Paper
In this paper, we investigate whether photographers' preference in shooting patterns could be a reliable index to represent the sightseeing value of a travel spot. To this end, we collected 30k geotagged images from 30 scenic spots over 4 continents. First, an effective framework based on convolution neural network (CNN) is proposed to establish th...

Emerging research revealed that the view-type of photos is not only related to the field of data sciences, such as the sentiment brought forth by sightseeing spots, but also in the field of social sciences about human emotions and behaviors. These potential usages of view-types trigger a challenging problem, that is to automatically distinguish the...
Article
Low-light is a challenging environment for image processing and computer vision tasks, either in contrast enhancement for better visibility and quality, or application oriented tasks such as detection. We found that the current trend of low-light enhancement research is heavily on quality improvement. In this work, we aim to shift the focus towards...
Article
Low-light is an inescapable element of our daily surroundings that greatly affects the efficiency of our vision. Research works on low-light imagery have seen a steady growth, particularly in the field of image enhancement, but there is still a lack of a go-to database as a benchmark. Besides, research fields that may assist us in low-light environ...

In psychology, theory-driven researches are usually conducted with extensive laboratory experiments, yet rarely tested or disproved with big data. In this paper, we make use of 418K travel photos with traveler ratings to test the influential "broaden-and-build" theory, that suggests positive emotions broaden one's visual attention. The core hypothe...
Conference Paper
At nighttime, reduced visibility could cause foreground and background images to appear to blend together. However, ambient light is always present in the natural environment, and as a consequence, it creates some contrast in darkness. In this paper, we formulate a visual analytic method that automatically unveils the contrast of dark images (i.e....
