Performs interactive audio synthesis using a previously trained auto encoder. VIsualizes hidden layer and allows for interaction with hidden units. W/ Andy Sarroff. See Andy's github (woodshop) for more interesting projects using Deep Learning and audio synthesis.
Interface for OpenCV's TV-L1 Duality Based Approach to Optical Flow. Does some additional tricks to speed up processing, allow for analysis of the spatio-temporal changes in flow, and visualize the results.
Public repository.
Multiscale Visualization ToolKit
Visualization Toolkit
An open library of computer vision algorithms
For streaming/logging emotiv eeg headset data
testing eeg encoding/decoding. this produces some gabor wavelets and co-registers the visualization and recording of eeg.
testing some encoding/decoding using EEG. this produces various animations that are co-registered with the recording of eeg.
ofxOpenCV linking against OpenCV 2.4.6.1, including libraries for OSX
CARPE is "Computational Algorithmic Representation and Processing of Eye-movements". It supports visualizations of film/eye-movements in columnar format, peak-through visualizations, heatmaps, optical flow analysis, gaze clustering, and many other visualization options. CARPE using NSWindow, Multiple Heatmaps, XML file settings, Difference of Heatmaps, GPU optimizations
Ph.D. Thesis from Goldsmiths, University of London entitled, "Audiovisual Scene Synthesis". Hosts all images and latex files.
For streaming/recording audio files, circular buffers (see pkmMatrix and pkmEXTAudioFile as well)
Sound synthesis library. Implements a number of feature databses including frame-based, segment-based, and sequence-based audio analysis/storing/retrieval. Also includes libraries for GPS-based synthesis including binarualization retrieval. Complements many other libraries including pkmBinaural and Memory Mosaic. Heavy dependence on vectorized ops using pkmMatrix and OSX's library Accelerate.
Interfacing libcluster for doing Variational Dirichlet Process Gaussian Mixture Models. Depends on Eigen3 and pkmMatrix. Libcluster included.
For performing GPS based concatenative sound synthesis, ANN retrieval based on GPS locations, HRTF based binauralization (mono->stereo using HRTF FFT-based Overlap-Add Convolution) using the IRCAM HRTF Database
pkmMatrix provides a lightweight Matrix class using the Accelerate.framework for vectorized operations
pkmFFT provide simple interfaces to the Accelerate.framework for performing vectorized FFT. pkmSTFT builds on pkmFFT to perform Short Time Fourier Transform efficiently using vectorized ops. Also handles options for windowing. pkmDCT provides a simple discrete cosine transform using Accelerate and pkmMatrix.
pkmEXTAudioFileReader and pkmEXTAudioFileWriter provides simple interfaces to reading and writing audio files.
Uses cURL to download from Freesound.org
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.
real time object detection using opencv and simple UI to select the object to track
Matlab scripts specific to the DIEM database
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.
CARPE is "Computational Algorithmic Representation and Processing of Eye-movements". It supports visualizations of film/eye-movements in columnar format, peak-through visualizations, heatmaps, optical flow analysis, gaze clustering, and many other visualization options. See http://thediemproject.wordpress.com for more details. Compuational and Algorithmic Representation and Processing of Eye-movements - OSX Version
[in progress] synthesis of audiovisual material from youtube!
Phase vocoder using pkmFFT and pkmMatrix. Does not seem to do as well as commerical applications. Would love it if anyone made use of this and improved upon it.
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.
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.
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).
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
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.
3d Object Tracking and Pose Estimation for the iPhone
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.
