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.

License This software implements the IBFS (Incremental Breadth First Search) maximum flow algorithm from. 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.

It includes automatic high-accurate registration (6D simultaneous localization and mapping, 6D SLAM) and other tools, e.g., a fast 3D viewer, plane extraction software, etc. Getting Started Components and HowTos. GPU Image & Video Processing SDK. SDK for fast image and video processing on GPU. GPU Accelerated Imaging SDK. Computer vision SDK on CUDA. GPU imaging products for developers. GPGPU SDK. Fastvideo has designed high performance SDK for image and video processing on GPU.
That SDK is a set of separate components which correspond to standard image processing pipeline for camera applications. We cover all image processing stages starting from camera raw image acquisition to JPEG compression with storage to RAM or HDD. All image processing is done completely on GPU and this leads to exceptionally high performance. We can also offer high speed imaging SDKs for non-camera applications.

ICBI - Iterative Curve Based Interpolation. ICBI (Iterative Curve Based Interpolation) is a single image superresolution technique described in Fast artifact-free image interpolation by Andrea Giachetti and Nicola Asuni, presented at BMVC 2008 and in the more detailed paper Real Time Artifact Free Image Upscaling" published on IEEE Transactions on Image processing.
Note that in the published papers there are small typos in three formulas (wrong indexes and a missing comma), but the linked paper and the code are correct. .

In this tutorial we will learn how to estimate the pose of a human head in a photo using OpenCV and Dlib. 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. Firefly's space.

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. Video grabing and image processing will be done using OpenCV library.
