Abstract Automatic bokeh is one of the smartphone’s essential photography effects. This effect enhances quality image where subject background gets out focus by providing a soft (i.e., diverse) background. Most smartphones have single rear camera that lacking to provide which effects need be applied kind images. To do same, depend on different software generate Blur, Color-point, Zoom, Spin, Bi...

PURPOSE To document reticular pseudodrusen (RPD) using multimodal imaging in French elderly subjects. METHODS A total of 494 subjects (970 eyes) aged 77 years or more, from the Alienor study, were examined in 2011 and 2012. Reticular pseudodrusen were defined as definite if they were present with at least two imaging methods among color retinal photographs, macular cube (20° × 15°) of spectra...

The proliferation of digital cameras co-located with eddy covariance instrumentation provides new opportunities to better understand the relationship between canopy phenology and the seasonality of canopy photosynthesis. In this paper we analyze the abilities and limitations of canopy color metrics measured by digital repeat photography to track seasonal canopy development and photosynthesis, d...

Spatial variability of soil parameters within fields complicates N fertilizer recommendations for corn (Zea mays L.) production. Thus, the ability to identify differences in crop N status within corn fields could lead to elticiencies in N fertilizer application and decreased ground water pollution. In this study, we digitized aerial color photographic transparencies using an eight-bit scheme to...
