Flash-exposure high dynamic range imaging: virtual photography and depth-compensating flash

نویسنده

چکیده

I present a revised approach to flash-exposure high dynamic range (HDR) imaging and demonstrate two applications of this image representation. The first application enables the creation of realistic ‘virtual photographs’ for arbitrary flash-exposure settings, based on a single flash-exposure HDR image. The second application is a novel tone mapping operator for flash-exposure HDR images based on the idea of an ‘intelligent flash’. It compensates for the depth-related brightness fall-off occurring in flash photographs by taking the ambient illumination into account.

Cmos Image Sensors with Multi-bucket Pixels for Computational Photography a Dissertation Submitted to the Department of Electrical Engineering and the Committee on Graduate Studies of Stanford University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy

When applied to multi-image computational photography such as flash/no-flash imaging, multiple exposure high dynamic range imaging, multi-flash imaging for depth edge detection, color imaging using active illumination, and flash matting, an image sensor that can capture multiple time-interleaved images would provide a dramatic advantage over capturing and combining a burst of images having diff...

Applications of Multi-Bucket Sensors to Computational Photography

Many computational photography techniques take the form, ”Capture a burst of images varying camera setting X (exposure, gain, focus, lighting), then align and combine them to produce a single photograph exhibiting better Y (dynamic range, signal-to-noise, depth of field). Unfortunately, these techniques may fail on moving scenes because the images are captured sequentially, so objects are in di...

Computational Photography Using a Pair of Flash/No-flash Images by Iterative Guided Filtering

In this paper, we present an iterative improvement of the guided image filter for flash/no-flash photography. The guided filter [8] utilizes a guide image to enhance a corrupted input image as similarly done in the joint bilateral filter [3, 12]. The guided filter has proved to be effective for such applications as high dynamic range compression, image matting, haze removal, and flash/no-flash ...

Professional portrait studio for amateur digital photography

We describe how to build a professional portable portrait studio that can be used with any consumer camera. The studio allows effortless off-line chroma-key insertion of backgrounds. Digital consumer cameras are designed for delivering acceptable images in typical outdoor or small room situations. The cameras fail when tungsten filament lamps are used. The built-in flash tube is too weak to fil...

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...
