CARPE allows one to begin visualizing eye-movement data in a number of ways. It currently supports low-level feature visualizations, clustering of eye-movements, model selection, heat-map visualizations, blending, contour visualizations, peek-through visualizations, movie output, binocular data input, and more.

Compuational and Algorithmic Representation and Processing of Eye-movements

Matlab scripts specific to the DIEM database

Uses cURL to download from Freesound.org

Does finger tracking, contour analysis, and different types of shape description for the hand contour using a 3D ROI around the hand-tracked by NITE middleware, using OpenCV 2.2, an OpenGL scene, and OpenNI. Developed in collaboration with Bruno Zamborlin.

Background modeling for foreground subtraction, tracks multiple blobs (people), their orientations (using leading motion vector), and has a nice visual display for seeing the results... video demonstration here: http://vimeo.com/22054133 - more info here: http://pkmital.com

track overhead using color and map tracked points to a new geometry using a homography transformation and calibration routine - some example test videos are provided in the bin/data directory of an overhead capture. The tracking transformation is useful for when you need a defined metric space of your tracking parameters, or need to account for different user heights in tracking their paths in a space.

3d Object Tracking and Pose Estimation for the iPhone

facial shape modeling, appearance modeling, and head pose recognition. Uses Jason Mora Saragih's FaceTracker code to track facial landmarks; GreatYao's aam-library for building/reprojecting the model (which may in fact be an uncited port of Jason's DeMoLib).

Audio analysis including real FFT/IFFT/STFT/ISTFT

Matrix class employing Apple's Accelerate framework (vDSP & cblas)

phase vocoder made simple

Calibrate head pose with respect to a screen (television/monitor) for an attention-based measure. Uses Jason Mora Saragih's FaceTracker, please contact him for the code.

openFrameworks based projection mapping for distorting or mapping a collection of drawing commands/videos/images etc... needed a lightweight and robust projection mapping utility though lpmt was too heavy. homography code stolen from lpmt.

Creates a dense SIFT image description and displays the image based on a PCA reprojection. Based on SIFT Flow code by Ce Lui, Jenny Yuen, and Antonio Torralba.

real time object detection using opencv and simple UI to select the object to track

Code from the Responsive Ecologies exhibition. Using overhead motion capture and 4 channels of video projection, users are invited to interact in an immersive cinematic environment. This code was developed for the installation in Waterman's Art Centre, London, UK, where artists captincaptin and Parag K Mital have been collaborating to install their piece, "Responsive Ecologies" for their residency during December 2010 and January 2011. The work occurs as part of a larger on-going collaboration with ZSL London Zoo and the Musion Academy.
