Case Studies
How King's College London used Encord to annotate videos 6.4x faster
Problem
Clinicians at King's College London (KCL) faced challenges in efficiently labeling medical data, particularly videos of pre-cancerous polyps in endoscopy, which was both time-consuming and costly. Employing clinicians for labeling was expensive and hindered the creation of large datasets necessary for AI model development.
Key Results
Clinicians at King's College London experienced significant improvements in labeling efficiency and reduced model development time by leveraging Encord's platform. With a 16x increase in efficiency for the most senior clinician and annotations completed 6.4x faster compared to using CVAT, Encord's embedded intelligence features and model assistance proved instrumental. This enhanced efficiency not only saved time but also reduced the cost associated with employing clinicians for data annotation, allowing them to focus on more productive tasks.
In a published study, “Novel artificial intelligence-driven software significantly shortens the time required for annotation in computer vision projects,” researchers at King’s College London annotated endoscopy videos of polyps 6.4x faster on Encord’s platform.
For researchers in the field, the accurate labeling of data remains “painstaking, cost-inefficient, [and] time-consuming.” Employing clinicians to label videos of pre-cancerous polyps is excessively expensive and thus inhibits the creation of large datasets.
Encord vs. CVAT
The study compared Encord, an enterprise-grade solution, with CVAT, an open-source tool, to analyze the speed and accuracy of labeling on each platform. Using a sample of polyp videos from the Hyper-Kvasir dataset, annotators leveraged the functionality offered on each platform.
On the Encord platform, annotators employed embedded intelligence features, including object tracking algorithms and functionality to train CNNs to annotate the data. After labeling a small number of frames, annotators built a micro-model that predicted the annotations for the remaining frames. With CVAT, the annotators drew bounding boxes & propagated them across frames using linear interpolation of box coordinates.
The increased efficiency and accuracy decreases the time investment required by clinicians to annotate data and frees up their time for more productive activities.
