Project Pages
Project NameBrief Summary
Action Recognition from Unconstrained Amateur Videos

We developed a systematic framework for recognizing realistic actions from unconstrained amateur videos which have tremendous variations due to camera motion, background clutter, changes in object appearance and scale, and so on.

Boundary Extraction by Lineal Feature Growing

Computer vision method for extracting lineal features, both curved and straight, from an image using extended local information to provide robustness and sensitivity.

Digital Analysis and Restoration of Daguerreotypes

Cluster computing allows standard digital analysis and restoration techniques to be applied to high-resolution microscopic digitizations of Daguerreotypes from the collection of the George Eastman House in Rochester. Knowing the image context of a feature (such as a small light spot) affects its probability of being noise (dust effect) or signal (foliage effect). Machine learning can be used to automate some subtle decisions.

Interactive Co-segmentation of Topically Related Images with Intelligent Scribble Guidance

We developed a user-friendly system to facilitate a user to perform interactive segmentation of objects of interest from a group of related images by providing scribble guidance.

Vision+Language

Grounded language learning by aligning text and video.

Mining the Power of 'Like' in Social Media Networks

'Like' has now become a very popular social function on social media networks by allowing users to express their positive opinions of certain objects. It provides an accurate way of gauging user interests and an effective way of sharing or promoting information in social media. We developed a system called LikeMiner using a heterogeneous network model and related mining algorithms to estimate the representativeness and influence of objects.

Planning as Satisfiability

Solving combinatorially challenging planning problems by encoding as Boolean satisfiability and applying state of the art SAT solvers.

Machine Translation

Methods for translating between natural languages (such as English and Chinese) by training statistical models on large collections of text.

Trains

The TRAINS project and its successors form one of the longest running research efforts on practical spoken dialogue: conversation undertaken with a specific task in mind.

Image Sentiment Analysis using Progressively Trained and Domain Transferred Deep Networks

We developed a robust algorithm for predicting the sentiment carried by an image using a progressive training strategy to derive a convolution neural network from samples with noisy sentiment labels

Leveraging User Generated Online Photos to Estimate and Monitor Air Pollution in Major Cities

We developed a novel system that makes use of everyday user shared photos to measure the air quality of different locations.
