Heatmaps – FiftyOne Tips and Tricks – October 6th, 2023

This week's FiftyOne tips and tricks blog delves into the use of heatmaps in computer vision. A heatmap is a visual representation that highlights areas of interest or intensity within an image, often used for tasks like object detection, pose estimation, or saliency mapping. In FiftyOne, heatmaps can be created by pointing to the location of a saved map or creating a map in memory and loading it instead. One real-world application of heatmaps is pose estimation, where they are used to create keypoint skeletons within images. The SWAHR Pose Estimation model from CVPR 2021 uses heatmaps for this purpose. By visualizing heatmaps on images, users can gain a better understanding of the model's focus and decision-making, ultimately enhancing its accuracy and performance.
