List of Packages for Computer Vision Developers (Ubuntu 14.04)

I am some-what intermediate developer mainly focusing on Computer Vision related development. I recently had to upgrade to Ubuntu 14.04 (Trusty) and turned out I rely on quite a lot of libraries and tools which are not available by default. Here is my list of packages : Feel free to mentions packages/libraries that you as … Continue reading List of Packages for Computer Vision Developers (Ubuntu 14.04) →

Direct Edge Alignment (D-EA)

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 … Continue reading Direct Edge Alignment (D-EA) →

Color Consistency from Multiple-View Images

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 … Continue reading Color Consistency from Multiple-View Images →

Details of Intra-Prediction in High Efficiency Video Coding (HEVC)

The new High Efficiency Video Coding (HEVC) standard has been recently developed by the Joint Collaborative Team on Video Coding (JCT-VC) which was established by the ISO/IEC Moving Picture Experts Group (MPEG) and ITU-T Video Coding Experts Group (VCEG). This new standard will replace the current H.264/AVC standard to deal with nowadays and future multimedia market trends. This post … Continue reading Details of Intra-Prediction in High Efficiency Video Coding (HEVC) →

Detection of Mitosis in Multispectral Breast Cancer Imagery

Mitotic count is an important parameter for the prognosis of breast cancer. However, mitosis detection is a challenging problem and has not been addressed well in the literature. Indeed, mitosis detection is very challenging since mitosis appear in image as small objects with a large variety of shapes, and they can thus be confused with … Continue reading Detection of Mitosis in Multispectral Breast Cancer Imagery →

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 →
