Burst photography for high dynamic range and low-light imaging on mobile cameras – Supplemental Material
At the finest scale of our coarse-to-fine alignment strategy, we require an alignment technique which performs well given large tile sizes but a very small search radius. In this context, techniques such as our previously-described fast subpixel L2 alignment, or even simpler techniques such as phase correlation [Kuglin and Hines 1975] are outperformed by a well-implemented brute-force procedure...
متن کاملBurst photography for high dynamic range and low-light imagingn mobile cameras
Cell phone cameras have small apertures, which limits the number of photons they can gather, leading to noisy images in low light. They also have small sensor pixels, which limits the number of electrons each pixel can store, leading to limited dynamic range. We describe a computational photography pipeline that captures, aligns, and merges a burst of frames to reduce noise and increase dynamic...

متن کاملHigh Dynamic Range Imaging as Applied to Paleontological Specimen Photography
Paleontological photography is a time-intensive process. Collections ranges, exhibit spaces, and outdoor field settings present challenging lighting regimes, many specimens have complex 3D shapes and are often fragile and difficult to move. Even in ideal conditions, the complexities of photography may result in inferior or inadequate coverage of specimens. Recently, software supporting High Dyn...
متن کاملTone Mapping for High Dynamic Range Cameras
High dynamic range images must be tone mapped before being displayed on devices with low output dynamic range. Two existing global tone mapping operators are evaluated and then a new improved operator using a sigmoid compression curve is proposed. It is then demonstrated through simulation and experimental results that an existing capture device, used previously only for simple logarithmic comp...
