The MPAI Metaverse Model (MPAI-MMM) - Technologies (MMM-TEC) specification is based on an innovative approach. As in the real world (Universe) we have animate and inanimate things, in an MPAI Metaverse (M-Instance) we have Processes and Items. Processes can animate Items (things) in the metaverse but can also act as a bridge between metaverse and universe. For convenience, MMM-TEC defines four classes of Processes: Apps, Devices, Services, and Users. Probably, the most interesting one is the User, defined as the…

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…

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…
