Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard

three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...

Studying Platelet-Based Depth Map Coding

The multi-view plus depth (MVD) format is a promising representation approach for 3D and free viewpoint video systems as it allows synthesizing more views at the decoder than those explicitly coded at the encoder. This format represents each view of a visual scene with both texture (array of color pixels) and a depth map which provides information about the 3D scene geometry. Thus, for the tran...

Analysis of Depth Map Resampling Filters for Depth-based 3D Video Coding

Depth map images are characterized by large homogeneous areas and strong edges. It has been observed that efficient compression of the depth map is achieved by applying a down-sampling operation prior to encoding. However, since high resolution depth maps are also needed for depth-based 3D coding tools, such as view synthesis prediction, an upsampling method that is able to recover the loss of ...

A SIMPLIFIED LAGRANGIAN MULTIPLIER APPROACH FOR FIXED HEAD SHORT-TERM HYDROTHERMAL SCHEDULING

This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

Multiple-view Video Coding Using Depth Map in Projective Space

In this paper a new video coding by using multiple uncalibrated cameras is proposed. We consider the redundancy between the cameras view points and efficiently compress based on a depth map. Since our target videos are taken with uncalibrated cameras, our depth map is computed not in the real world but in the Projective Space. This is a virtual space defined by projective reconstruction of two ...
