Vision Controlled Quadcopter Flight

December 9, 2015

7

Just completed (8th Dec, 2015) the Aerial Robotics course in HKUST (ELEC6910P) by Prof. SHEN Shaojie (my PhD supervisor). Most of the course credit were on the completion of the projects. Course TAs were Su Kunyue and Yang Zhengfei. My project partners were Sun Lin and Sun Ting The projects eventually connected together to make a vision […]

Color Consistency from Multiple-View Images

September 17, 2015

0

Abstract In this paper we address the problem of multiview color consistency. We propose to use a graph model of 3d positions obtained using matched dense feature points. We define an energy functional on this model which captures relationship of the colors across views while also imposing a smoothness cost to obtain optimal colors for the 3d […]

Direct Edge Alignment (D-EA)

September 14, 2015

Abstract There has been a paradigm shifting trend towards feature-less methods due to their elegant formulation, accuracy and ever increasing computational power. In this work, we present a direct edge alignment approach for 6-DOF tracking. We argue that photo-consistency based methods are plagued by a much smaller convergence basin and are extremely sensitive to noise, changing illumination […]

Photometric Stereo

Project Summary A fixed object is observed with a fixed camera under different light direction. See figure below for the setup. The aim of the project is to infer depth model from these set of images.   Acknowledgement This project is a part of the Computer Vision course (COMP 5421) during spring 2014. The project […]

Outlier Rejection with Tensor Voting

April 12, 2014

0

Project Summary Given a 3D point cloud the task is to filter out the noisy points. In the project we use the ‘Tensor Voting Method’ [1,2] for outlier detection. Acknowledgement This project is a part of the Computer Vision course (COMP 5421) during spring 2014. The project partners were Manohar Kuse (myself) and Sunil Jaiswal. The […]

Qt is a very flexible and versatile library. In one of my previous blog entry I had described how is it possible to create simple GUIs with Qt. If you are not very familiar with Qt, you may like to view my previous blog entry on Qt where in I have put up a short […]

3D Reconstruction with Single View

Project Summary We create a 3D model of flat objects from single view. The method used is based on a paper by Criminisi [1]. Acknowledgement This project is a part of the Computer Vision course (COMP 5421) during spring 2014. The project partners were Manohar Kuse (myself) and Sunil Jaiswal. The course instructor was Prof. C. […]
