A Solution to the Composition Problem in Object-Based Video Coding
نویسندگان
چکیده
In this paper, we introduce the composition problem associated with object-based video coding and propose a solution to this problem. Although the object-based rate control algorithm can provide the overall coding gain, it may create the composition problem due to different temporal resolutions in object encoding. By checking shape changes of video objects, we can minimize the possibility of the composition problem at the encoder. At the decoder, we can also apply hole detection and recovery algorithms to eliminate the effect of the composition problem to the human visual system.

Recognition of Visual Events using Spatio-Temporal Information of the Video Signal
Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...
متن کاملA Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies
In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

متن کاملروشی جدید برای اختفای خطا در فریم‌های ویدئو با استفاده از شبکه عصبی RBF
Transmission of compressed video over error prone channels may result in packet losses, which can degrade the image quality. Error concealment (EC) is an effective approach to reduce the degradation caused by the missed information. The conventional temporal EC techniques are always inefficient when the motions of the video object are irregular. In this paper, in order to overcome this problem,...
متن کاملEncoding and transcoding multiple video objects with variable temporal resolution
A key advantage of object-based coding schemes is that the quality of each video object may be varied. In this paper, we describe the problem associated with varying the temporal quality of multiple video objects, also referred to as the composition problem. We propose a solution to this problem that that is based on changes in the shape boundaries over time. Finally, we discuss how this shape ...
