CAVE | Software: RASCAL - Download. Camera Streak For Android Simulates Long Exposure Photography. Commendable camera-based Android apps are hard to come by. However, apps from said genre do tend to attract a lot of attention. Users like to be creative with the way they take pictures and sometimes, the plain stock camera app just doesn’t cut it. Camera Streak is a fairly new arrival on the Market that provides you with the tools to set your inner photographer free. The freeware simulates long exposure photography by capturing and superimposing multiple snaps, allowing users to capture light streaks (trails of a light source) and motion, that is, different instances of a scene merged within a single picture via a simple and easy-to-use user interface.
More after the jump. The results aren’t as good as the real thing, of course, but they are impressive, to say the least. Add a tinge of creativity, snap and upload, and you’ll have your friends going “how did you do that?” Pressing menu on the device brings up the application menu, wherefrom users can access the Settings screen.

Laplacian Pyramid Toolbox. Graphics Software. Enblend/Enfuse - combine images with no seams. HDR-VDP. Visual difference metrics can predict whether differences between two images are visible to the human observer or not. Such metrics are used for testing either visibility of information (whether we can see important visual information) or visibility of noise (to make sure we do not see any distortions in images, e.g. due to lossy compression). The image below shows how two input images, a reference image (upper left) and a distorted image (lower left), are processed with the VDP to produce a probability of detection map (right). Such probability of detection map tells how likely we will notice a difference between two images for each part of an image.
Red color denotes high probability, green - low probability. High Dynamic Range Visible Difference Predictor (HDR-VDP) can work within the complete range of luminance the human eye can see. The HDR VDP sources can be downloaded from the SourceForge project page. Pfstools and FFTW packages must be installed before compiling HDR VDP.
