Exploring the Up-sampling Filter for Video applications (EVC-TEC) standard

  • Post author:
  • Post category:MPAI

A method typically used in video coding is to down-sample to half the input video frame before encoding. This reduces the computational cost but requires an up-sampling filter to recover the original video resolution in the decoded video to reduce as much as possible the loss in visual quality. Currently used filters are bicubic and Lanczos, Figure 1 – Up-sampling Filters for Video application (EVC-UFV) In the last few years, Artificial Intelligence (AI), Machine Learning (ML), and especially Deep Learning…

An introduction to the Neural Network Watermarking Call for Technologies

Introduction During the last decade, Neural Networks have been deployed in an increasing variety of domains and the production of Neural Networks became costly, in terms of both resources (GPUs, CPUs, memory) and time. Moreover, users of Neural Network based services more and more express their needs for a certified service quality. NN Traceability offers solutions to satisfy both needs, ensuring that a deployed Neural Network is traceable and any tampering detected. Inherited from the multimedia realm, watermarking assembles a…

Standards have a divine nature Inside MPAI The MPAI mission An overview of MPAI standards Abstract In five years, MPAI – Moving Picture, Audio, and Data Coding by Artificial Intelligence, the international, unaffiliated, not-for-profit association developing standards for AI-based data coding – has been carrying out its mission, making its results widely known and its status recognised. However, not all are clear why MPAI was established, which are its distinctive features, and why it stands out among the organisations developing…

1. Introduction The Connected Autonomous Vehicle (CAV) specified by Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) - Technologies (CAV-TEC) V2.0 is a system that instructs a vehicle with at least three wheels to reach a Destination from a current Pose at the request of a human or a process. It does so by exploiting information captured and processed by the vehicle and communicated by other CAVs while respecting the local traffic law, Figure 1 represents an example of the type of…

Communicating avatars in worlds

  • Post author:
  • Post category:MPAI

An avatar is generally intended as a representation of a real or fictitious human in a virtual space. Research has dedicated much effort to creating and animating realistic avatars. However, the scope of use is typically assumed to be a closed environment such as a proprietary video game. Therefore, the portability of avatars has seldom been a priority. Some 30 years ago, the Humanoid Animation (H-Anim) standard was developed that defined a human skeleton composed of joints, segments, and sites…

An overview of the MPAI Metaverse Model – Technologies standard

  • Post author:
  • Post category:MPAI

The MPAI Metaverse Model - Technologies standard - in short, MMM-TEC V2.0 - is the first open metaverse standard enabling independently designed and implemented defines a metaverse instance (that MMM-TEC calls M-Instances) and clients to interoperate. These are the main MMM-TEC elements: The Architecture is based on Processes acting on Items based on the Rights they hold. Items represent any abstract and concrete objects in an M-Instance. Processes - possibly in different M-Instances - communicate using the Inter-Process Protocol (IPP).…
