Illustration of three coordinate systems in the task: image, tracker tool, and camera (or world) coordinate systems. Computer Vision News Computer Vision News 32 What they did: 1) published a large, ethicallyapproved in vivo ultrasound dataset comprising over 2,000 scans (> 1 million frames) collected from the forearms of 85 diverse volunteers, with synchronised pose data captured by a high-precision optical tracker. 2) developed comprehensive step-bystep tutorials that helps the public and wider researchers understand the basics of this task, accompanied by easy-to-use modular baseline code, allowing anyone interested to get started quickly. 3) established a standardised benchmark for fair comparison across methods in this field, supported by rigorously defined metrics and a transparent ranking scheme, which will no doubt contribute towards the growing need to establish a standard in this field. 4) released the challenge report paper with comprehensive background introduction and literature review, describing the challenge design and dataset, and presenting a comparative analysis of the submitted methods across multiple evaluation metrics.
