We have already presented the system diagram of the Autonomous User (A-User), an autonomous agent able to move and interact (converse, etc.) with another User in a metaverse. The latter User may also be an A-User or may be under the direct control of a human and is thus called a Human-User (H-User). The A-User acts as a “conversation partner in a metaverse interaction” with the User. This is the first of a planned sequence of posts having the goal…
The Mayflower Pilgrims left a world they considered oppressive to a new one that they expected would be challenging but more hospitable. With the development of one of its standards – the MPAI Metaverse Model – some MPAI members virtually left this world not because it was unfriendly but because they thought that the new virtual one would be more or differently attractive. Like the Pilgrims, these MPAI members had to face a new world that they wanted to populate.…
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…
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…
