Emotion Recognition for MS Cognitive Services

Established: July 1, 2015

Emotion Recognition takes an image with faces as an input, and returns the confidence across a set of emotions for each face in the image, as well as bounding box for the face (using MS Face API). The algorithm infers emotions from appearance using a custom Deep Convolution Network. To improve labeling, we labeled each image with more than 10 taggers using crowd source, which allowed us to learn probability distribution for each image. We are also sharing…

Eye-Gaze Tracking for Improved Natural User Interaction

Established: April 12, 2014

We develop novel eye-gaze tracking technologies in order to make eye-gaze tracking technology ubiquitously available for improved natural user interaction (NUI).   In particular, we investigate two approaches: Active IR lighting: We investigate the possibility of using multiple IR lights around a display. The key idea is to use many (more than 4) IR lights distributed around a monitor border. RGB + Depth: We leverage both RGB camera and depth sensor already available in Kinect…

Besides this, our work also includes how to get 3D object model in real-time, augmented reality…

Audio Spatialization and Multichannel Acoustic Echo Cancellation (AEC)

Established: August 9, 2008

About the System In multiparty conferencing, one hears voices of more than one remote participants. Current commercial systems mix them into a single mono audio stream, and thus all voices of remote participants will sound like coming from the same location when using loudspeakers or from inside the listener's head when using headphones. This is in sharp contrast to what happens in real life where each voice has its distinct location. We have built and…

Personal Telepresence Station

Established: July 29, 2008

With globalization and workforce mobility, there is a strong need of research and development of advanced infrastructures and tools to bring immersive experience into teleconferencing so people across geographically distributed sites can interact collaboratively. The Personal Telepresence Station project aims at bringing Telepresence experience to offices. We try to replicate the same experience people enjoy in face-to-face meetings such as gaze awareness and spatial audio.

Speaker Verification: Text-Dependent vs. Text-Independent

Established: August 20, 2006

Speaker verification is the process of verifying the claimed identity of a speaker based on the speech signal from the speaker (voiceprint). There are two types of speaker verification systems: Text-Independent Speaker Verification (TI-SV) and Text-Dependent Speaker Verification (TD-SV). TD-SV requires the speaker saying exactly the enrolled or given password. Text independent Speaker Verification is a process of verifying the identity without constraint on the speech content. Compared to TD-SV, it is more convenient because…

Projector-Whiteboard-Camera System for Remote Collaboration

Established: October 2, 2004

Visual Echo Cancellation for Seamless Integration of Remote Sites About In a typical remote collaboration setup, two or more projector-camera pairs are "cross-wired" to form a full-duplex system for two-way communication. A whiteboard can be used as the projector screen, and in that case, the whiteboard serves as an output device as well as an input device. Users can write on the whiteboard to comment on what is projected or to add new thoughts in…

Whiteboard

Established: August 6, 2002

Digital Technology for Effective Whiteboard Use Introduction Whiteboard is ubiquitous and will exist for foreseeable future, but its content is hard to archive and share. While digital cameras can be used to capture whiteboard content, the image is usually taken from an angle, contains irrelevant information, and has shadows. We have developed an intelligent and automatic technique to reproduce the whiteboard content as a crisp and faithful image which can be archived or shared with…

Eye-Gaze Correction for Video Telecommunications

Established: May 1, 2002

The lack of eye contact in desktop video teleconferencing substantially reduces the effectiveness of video contents. While expensive and bulky hardware is available on the market to correct eye gaze, researchers have been trying to provide a practical software-based solution to bring video-teleconferencing one step closer to the mass market. This paper presents a novel approach that is based on stereo analysis combined with rich domain knowledge (a personalized face model). This marriage is mutually…

Human Action and Activity Recognition

Established: August 9, 2001

Expandable Data-Driven Graphical Modeling of Human Actions Based on Salient Postures. This paper presents a graphical model for learning and recognizing human actions. Specifically, we propose to encode actions in a weighted directed graph, referred to as action graph, where nodes of the graph represent salient postures that are used to characterize the actions and are shared by all actions. The weight between two nodes measures the transitional probability between the two postures represented by…

Re-rendering from a Sparse Set of Images

Established: June 1, 2001

We present a framework for view-dependent rendering from arbitrary viewpoints and relighting under novel illumination conditions of a real object from a sparse set of images and a pre-acquired geometric model of the object. Using a 3D model and a small set of images of an object, we recover all the necessary photometric information for subsequent rendering. We recover the illumination distribution, represented as a hemisphere covering the object, as well as the parameters of…

Face Modeling

Established: May 5, 2001

Overview 3d Modeling. Generating realistic 3D human face models and facial animations has been a persistent challenge in computer vision and graphics. We have developed a system that constructs textured 3D face models from videos with minimal user interaction. Our system takes a video sequence of a face with an ordinary video camera. After five manual clicks on two images to tell the system where the eye corners, nose tip and mouth corners are, the…

VisualPanel

Established: November 15, 2000

Transforming an ordinary paper into a wireless mobile input device. Virtual mouse, keyboard and 3D controller with an ordinary piece of paper. Abstract In many intelligent environments, instead of using conventional mice, keyboards and joysticks, people are looking for an intuitive, immersive and cost-efficient interaction device. We are developing a vision-based gesture interface prototype system, VisualPanel, which employs an arbitrary quadrangle-shaped panel (e.g., an ordinary paper) and a tip pointer (e.g., fingertip) as an intuitive,…

VisualScreen

Established: November 5, 2000

Transforming an ordinary screen into a Touch Screen with a camera. About Touch screens are very convenient because one can directly point to where it is interesting. This paper presents an inexpensive technique to transform an ordinary screen into a touch screen using an ordinary camera. The setup is easy: position a camera so it can see the whole screen. The system calibration involves the detection of the screen region in the image, which determines…

A Flexible New Technique for Camera Calibration

Established: December 2, 1999

We propose a flexible new technique to easily calibrate a camera. It is well suited for use without specialized knowledge of 3D geometry or computer vision. The technique only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known. Radial lens distortion is modeled. The proposed procedure consists of a closed-form…
