Double-exposure Photography

Computational Photography: Coded Exposure and Coded Aperture Imaging

The emerging field of computational photography is exploring the possibilities of digital photography beyond the imitation of film cameras. Novel illumination, optics, sensors, and processing methods are employed to expand the set of images that cameras can create. This thesis introduces the field of computational photography and presents two exemplary techniques that address the problem of blu...

Robotics in Arts: Mobile Robot for Long-Exposure Photography

This work deals with creation of affordable computer vision based visual art systems with the help of open source solutions found on market. The particular project described in this paper has been created with the help of Arduino board, programmed with Processing and uses some OpenCV features to create photos with long exposure time. With the help of the specially designed software one is able ...

Bilateral Filter Based Compositing for Variable Exposure Photography

Compositing a scene from multiple images is of considerable interest to graphics professionals. Typical compositing techniques involve estimation or explicit preparation of matte by an artist. In this article, we address the problem of automatic compositing of a scene from images obtained through variable exposure photography. We consider the High Dynamic Range Imaging (HDRI) problem and review...

Averaging double-exposure speckle interferograms.

Speckle-fringe quality can be improved by averaging many statistically independent interferograms together, which are generated by shifting the object's illumination angle. A technique applicable to double-exposure speckle interferograms obtained from processing two speckle patterns is described. It utilizes a computer-controlled stepping motor to tilt the object illumination, which is repeatab...
