Vision Controlled Quadcopter Flight

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 … Continue reading Vision Controlled Quadcopter Flight →

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 … Continue reading Photometric Stereo →

Outlier Rejection with Tensor Voting

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 … Continue reading Outlier Rejection with Tensor Voting →

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. … Continue reading 3D Reconstruction with Single View →

Magnetic Lasso from Scratch – Intelligent Scissors

Project Summary The objective of this project is to understand the algorithm beneath the magnetic lasso tool. Magnetic lasso tool is one of the common tools found in tools like Gimp, Adobe Photoshop etc. In this project we build a tool which allows a user to cut an object out of an image and paste … Continue reading Magnetic Lasso from Scratch – Intelligent Scissors →

Image Mosaic

Abstract: Image mosaicking is a process in which a larger image is formed from small pieces of smaller images. In this short fun project, I have tried to implement a simple algorithm to do this task. This algorithm is based on block by block histogram matching. Download: You can download my Matlab implementation and test … Continue reading Image Mosaic →

Automatic Machine Written Document Reader

Project Summary The aim of this project is to automatically read the printed characters, identify them. Later these identified text is to be passed to a syntetic speech generator which would read aloud the text. The system implemented by us takes an image with characters written on it as the input. The image has a white back-ground and … Continue reading Automatic Machine Written Document Reader →
