Heatmap Regression
A classical paradigm in human pose estimation and keypoint detection in which a Gaussian heatmap is generated for each keypoint as the supervision signal, the network outputs the probability of each pixel being a keypoint, and inference takes the heatmap peak as the predicted location.
Timeline (last 90 days)
Traditional spinal keypoint detection methods typically use heatmap regression, but they struggle to distinguish the corners of adjacent vertebrae.
Heatmap regression is a classic paradigm in human pose estimation and keypoint detection: it generates a Gaussian heatmap for each keypoint as the supervision signal, and at inference takes the peak coordinate as the predicted location.
The limitations of heatmap regression include: Gaussian heatmaps overlap and blur when multiple keypoints are close together, and the heatmap resolution is affected by downsampling and requires extra handling.
