3D Computer Vision: Multiple View Geometry, Structure from Motion, Multi-View Stereo, Photometric Stereo, Structured Light, Shape from Silhouette

• Created the datasets to evaluate the performance of algorithms under varied problem conditions (visual/geometric properties) so that the conditions under which a specific algorithm works reliably can be discovered;
• Created the datasets to evaluate the performance of algorithms under varied problem conditions (visual/geometric properties) so that the conditions under which a specific algorithm works reliably can be discovered;
• Developed Blender projects and scripts to generate synthetic datasets with varied material and geometric properties, which make it possible to discover the problem conditions under which a specific algorithm works reliably.

• Developed a description-based interface to 3D reconstruction so that a successful reconstruction result can be achieved given a valid description of the object;
• Implemented multiple 3D reconstruction algorithms, each registered to a different sub-volume of the problem space. The implemented algorithms include Patch-based Multi-View Stereo, Example-based Photometric Stereo, Gray-code Structured Light, and Volumetric Visual Hull;
• Developed an algorithm & evaluation pipeline that runs algorithms on both real-world and synthetic datasets, compute and visualize quantitative results for evaluation.

• Implement and maintain an open source Multiple View Geometry library with minimum third-party dependencies;
• Implement incremental Structure from Motion (SfM) using open3DCV.

• Implement sequential Structure from Motion (SfM) using open3DCV and write a detailed tutorial for educational purpose.

• Developed 3D reconstruction algorithms and high-level abstraction for everyday objects;
• Multi-projector calibration, header tracking using kinect and magnetic tracker.

• Implemented from scratch a robust cylindrical image stitching algorigthm in C++, which includes feature detection/extraction, focal length estimation, planar plane to cylindrical surface transformation, feature-based image alignment algorithms, etc.

• Course project of CPSC 554M - Topics in Human Computer Interaction. Personalize video thumbnails based on viewing behaviour for fast video re-searching.

• Course project of EECE 418 - Human Computer Interface. A travel agent APP that uses online social connections and common interests to match potential backpackers.

• Use decision stumps and decision trees as base learners, implemented different split criteria for the decision tree, including information gain of ID3 and information gain ratio of C4.5;
• Implement post-prune for the tree construction algorithm using reduced error pruning;
• Implement one-vs-rest multi-class classification using decision stumps as base learners, and SAMME using decision trees as base learners.

• Investigate the performance of Adaboost when three different weak classifiers - decision stump, decision tree, and weakened SVM are used as the base classifier.

• Implemented several pixel-based and color histogram-based shot boundary detection algorithms with an GUI interface for easy browsing.

• Hand gesture segmentation using color and depth cues, and recognition using extracted hand geometric features.

• Implemented independently an iClicker-like Android APP to send/receive information, and a PC program that acts as a server using multi-thread Socket and has information processing functionalities.
