Examples of heatmap generation and region of interest mask inference. Top: Global input images show the entire view of a maternal womb captured on MRI in all three planes. Middle: Corresponding heatmaps derived from the last convolutional layer identify high-value areas for attention-based learning. Increasing activation values correspond to the color spectrum from violet to yellow. Bottom: Application of a 2D Gaussian mask generates a re-weighted heatmap highlighting the region of interest.
