Mobile multi-flash photography
Multi-flash (MF) photography offers a number of advantages over regular photography including removing the effects of illumination, color and texture as well as highlighting occlusion contours. Implementing MF photography on mobile devices, however, is challenging due to their restricted form factors, limited synchronization capabilities, low computational power and limited interface connectivi...
متن کاملFlash photography-induced maculopathy
OBJECTIVE To report a flash photography-induced maculopathy. METHODS A professional photographer blinded himself accidentally and he consulted 3 days after the event with a scotoma in his dominant left eye. A unilateral acute light-induced maculopathy with hemorrhage was observed. The lesion was studied with colour photography, fluorescein and indocyanin angiography, autofluorescence imaging ...
متن کاملTime-Lapse Light Field Photography With a 7 DoF Arm
A photograph taken by a conventional camera captures the average intensity of light at each pixel, discarding information about the angle from which that light approached. Light field cameras retain angular information about the rays they collect, allowing re-integration of rays during post processing. Consumer light field cameras have small apertures, and laboratory camera arrays with large ba...
متن کاملLight Field Photography with a Hand-held Plenoptic Camera
This paper presents a camera that samples the 4D light field on its sensor in a single photographic exposure. This is achieved by inserting a microlens array between the sensor and main lens, creating a plenoptic camera. Each microlens measures not just the total amount of light deposited at that location, but how much light arrives along each ray. By re-sorting the measured rays of light to wh...
