      Here's a test of a screen manager addon for OpenFrameworks which allow to warp a scene using a grid. It supports multiscreen, including soft edge blending (although this part needs some more real world testing) This is for an upcoming project with interactive projection mapping using my Criaturas project (http://vimeo.com/6053589) built using OpenFrameworks

          Using a combination of computer vision, particle generators and Vector Data, i created a fluid simulator inside a box. The simulation is based on spring/joints connections with starting and ending point both fixed and with huge mass. Fluid can move only inside box boundaries and react to viewer position and movements using OpenCV and infrared camera/emitter. In the video the simulation is trigged by mouse movements for convenience.

            Another from Dhruv's vaults www.hplustech.com Notes from Dhruv: This is a simple program which detects hands in a yellowish spectrum using Disparity Maps. It then takes the yellowish spectrum and subtracts from the background leaving only the hands to be detected in this case. About H+ www.hplustech.com H+ is a group of visionary individuals who are leading a paradigm shift in the field of human-computer interaction (HCI). We create customizable intuitive gesture (Air-Motion) based systems & displays (3D). The philosophy of H+ is technology should adapt to human behaviour and not vice versa.
 We believe in humanizing technology.

              Disclaimer: In real life the game runs much smoother then the video as my capturing software is limited @ 30 fps. This is the first official "lars" videogame. It is targeted at little kids so the gameplay is "simple". The player controls the boat (by key or motion) and tries to catch lars that has jumped out of an airplane. There are different difficulty levels to cater different age groups.

                    • OpenCV Face Detection: Visualized

                      This video visualizes the detection process of OpenCV's face detector. The algorithm uses the Viola Jones method of calculating the integral image and then performing some calculations on all the areas defined by the black and white rectangles to analyze the differences between the dark and light regions of a face. The sub-window (in red) is scanned across the image at various scales to detect if there is a potential face within the window. If not, it continues scanning. If it passes all stages in the cascade file, it is marked with a red rectangle. But this does not yet confirm a face. In the post-processing stage all the potential faces are checked for overlaps. Typically, 2 or 3 overlapping rectangles are required to confirm a face. Loner rectangles are rejected as false-positives. This visualization was done as part of the documentation for CV Dazzle, camouflage from face detection. For more information, visit http://cvdazzle.com
