Approval of new WG and new PAR: Standard for Deep Intermediate Feature Coding (DCSC-23-N0002)

Motion to approve the new PAR of Standard for Deep Intermediate Feature Coding (Mover: Prof. Siwei Ma; Second: Dr. Wen Ji) Dr. Wenhan Yang gave a brief introduction of the PAR. Attendees reviewed the PAR, and unanimously approved as presented without objection.

Title: Standard for Deep Intermediate Feature Coding

Scope: This standard defines a set compression, decompression, and packaging tools and mechanism for intermediate features of deep neural networks, including but not limited to deep convolutional network, transformer, diffusion models, that are widely adopted in intelligent processing and analytics applications, e.g. intelligent transportation, smart cities.

A new WG shall be established at the same time with the name “Multi-Modality Feature Coding Working Group (C/DC/MFC) “. This WG aims to develop a series feature related standards which should be the fundamental technology of feature representation and coding. The chair of the WG is Prof. Lingyu Duan.

The next meeting is tentatively snqqcheduled in June, 2024. (The meeting notice will be published on our website one month before the meeting). Remote attendees can request to set up a teleconference service at least one week before the meeting.

This meeting minutes was approved on the meeting.

The meeting closed at 17:00 on March 23^rd, 2024.
