박사학위논문. 1.1 Overview There are a lot of very low bitrate channels today, such as public switched telephone networks (PSTN), radio channel, and computer data networks.
These channels require bitrate lower than 64 kbps and are initially designed to transmit speech or text data. Recently, there has been an increasing demand for video communication using such very low bitrate channels, which can be easily accessed without additional expansion of channel facilities. Considering these accessibility conditions, it is required to develop a more efficient video coding scheme to realize the video communication at such low bitrate. The main technical issue to accomplish this is how we can get the necessary bitrate with sufficient image quality. In this chapter, we discuss an efficient spatial transform-based motion estimation method which dose not bring about blocking artifacts. Faster smiles on OpenCV with TBB - The Impossible Code.

Convexity Shape Prior This library implements the TR_Convexity algorithm for binary image segmentation with convexity shape prior and L1 color separation term (see OneCut below). The library includes matlab files, C++ code/executable for maxflow/mincut and user interface for scribbles. The LSA_TR library is a general optimization algorithm for arbitrary binary pairwise energies. OneCut with Seeds The OneCutWithSeeds library is an interactive figure/background segmentation tool.
3D Delaunay Triangulation on the GPU. School of Computing, National University of Singapore Abstract We present the first 3D Delaunay triangulation algorithms that effectively utilize the massive parallelism of the GPU.

Goldberg, Sagi Hed, Haim Kaplan, Pushmeet Kohli, Robert E. Tutorial. Tutorial Abstract: Image segmentation has come a long way.
Using just a few simple grouping cues, one can now produce rather impressive segmentation on a large set of images. Behind this development, a major converging point is the use of graph based technique. Graph cut provides a clean, flexible formulation for image segmentation. It provides a convenient language to encode simple local segmentation cues, and a set of powerful computational mechanisms to extract global segmentation from these simple local(pairwise) pixel similarity. In this tutorial, we will summarize current progress on graph based segmentation in four topics: Code & Data – 南开大学媒体计算实验室. 注意事项: These resources might need password to be opened.

In many applications, we need to know how the head is tilted with respect to a camera. In a virtual reality application, for example, one can use the pose of the head to render the right view of the scene. In a driver assistance system, a camera looking at a driver’s face in a vehicle can use head pose estimation to see if the driver is paying attention to the road. Firefly's space.

Goal: 3D Head Tracking in Video « : How a simple model can do big. Free-D. Written By: urbeller - May• 14•13 In this post, I will describe my own implementation of a head tracker. 3D Head Tracking (HT) consists of inferring the 3D orientation and displacement of the head, often from a (single) video source. Here, the video source will be a Logitech C910 webcam. Of course, any webcam will do.
