Technical Program Highlights

Keynote lecture

Learnt compression for visual analytics on the edge

This talk will discuss how to compress images to optimize for visual analytics tasks such as object detection and image classification, and its application for  edge-assisted visual computing. We will contrast two different approaches: image compression at the mobile followed by decompression and visual analytics at the server, vs. splitting the deep learning computing between the mobile and the server and compressing the intermediate analytics features. We illustrate effective approaches for compressing analytics features and end-to-end training to optimize the rate-analytics trade-off. We demonstrate that split computing not only yields superior rate-analytics performance but also substantially reduces the mobile computing time. We further describe how to generate and code the analytics features progressively, to facilitate adaptation to the bandwidth  between the mobile and the edge, and the  battery status at the mobile device.

She received the NYU Tandon Distinguished Teacher Award in 2016.

Workshop scope

Multimedia signals – speech, audio, images, video, point clouds, light fields, … – have traditionally been acquired, processed, and compressed for human use. However, it is estimated that in the near future, the majority of Internet connections will be machine-to-machine (M2M). So, increasingly, the data communicated across networks is primarily intended for automated machine analysis. Applications include remote monitoring, surveillance, and diagnostics, autonomous driving and navigation, smart homes / buildings / neighborhoods / cities, and so on. This necessitates rethinking of traditional compression and pre-/post-processing methods to facilitate efficient machine-based analysis of multimedia signals. As a result, standardization efforts such as MPEG VCM (Video Coding for Machines) and JPEG AI have been launched.

Both the theory and early design examples have shown that significant bit savings for a given inference accuracy are possible compared to traditional human-oriented coding approaches. However, a number of open issues remain. These include a thorough understanding of the tradeoffs involved in coding for machines, coding for multiple machine tasks, as well as combined human-machine use, model architectures, software and hardware optimization, error resilience, privacy, security, and others. The workshop is intended to bring together researchers from academia, industry, and government who are working on related problems, provide a snapshot of the current research and standardization efforts in the area, and generate ideas for future work. We welcome papers on the following and related topics:
