Software

Optical Flow

• Source code for "Accurate Optical Flow via Direct Cost Volume Processing".

Weakly Supervised Semantic Segmentation

• Source code for "Learning to Segment Under Various Forms of Weak Supervision".

Background subtraction and Vide Segmentation

• Source code for "GOSUS: Grassmannian Online Subspace Updates with Structured-sparsity".

Interactive Segmentation and Contour Completion

• Source code for "Incorporating User Interaction and Topological Constraints within Contour Completion via Discrete Calculus".

Cosegmentation

• Source Code for "Scale Invariant Cosegmentation for Image Groups" can be downloaded here. This code base uses OpenCV-2.1 to compute the data/smooth term. If you are using OpenCV-2.2 or later version, you might want to replace the GMM component with this one. Please contact me at jiaxu [at] cs.wisc.edu for the password. All rights reserved.
• Source code for "Random Walks based Multi-Image Segmentation: Quasiconvexity Results and GPU-based Solutions".

Real-time Simulation of Natural Phenomena

• Once upon a time, we (with my awesome college classmates) built a general particle system for wonderland, and used it to simulate several natural phenomena like rain, snow, and fire.etc in a collaborative 3D virtual world. Report and code could be downloaded here.
