1 Efficient Representation and Coding of Omni - Directional Video Using Mpeg - 4

نویسنده

چکیده

This paper presents an efficient approach for representation and coding of omni-directional video that applies exclusively available MPEG-4 technology, i.e. the combination of 3D Mesh Objects with video textures. This allows application of efficient spherical projections such as equal-area projections or a faceted representation of the image information. Any 3D MPEG-4 player can be used to render and display the omni-directional video interactively. This simple but universal approach enables full competition at the encoder side while providing full interoperability at the decoder side.

A Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

Using BELBIC based optimal controller for omni-directional threewheel robots model identified by LOLIMOT

In this paper, an intelligent controller is applied to control omni-directional robots motion. First, the dynamics of the three wheel robots, as a nonlinear plant with considerable uncertainties, is identified using an efficient algorithm of training, named LoLiMoT. Then, an intelligent controller based on brain emotional learning algorithm is applied to the identified model. This emotional l...

High efficient sprite coding with directional spatial prediction

Sprite is an efficient and concise method for representation of background video object, which is typically compressed with the MPEG-4 object-based coding technique. Due to the property of background video object, sprite image often comprises many flat and texture-correlation regions. In order to fully exploit spatial redundancy, this paper proposes an idea by utilizing directional spatial pred...

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks

The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

H.264 Based coding of omnidirectional Video

Omnidirectional video is an adequate image-based scene representation data format for interactive walkthroughs or surround viewing of a scene over the Internet. While efficient compression is a key issue in this context, the properties of omnidirectional video are not in line with the assumptions that are made about video sequences by modern compression standards like MPEG-4 AVC/H.264. We intro...
