How to convert points to heatmap in Qupath?


I have a bunch of points annotated for a cancer image in Qupath. I want to generate a density heat map using those points. Is there a way for me to do and visualise the said heatmap in Qupath?


There’s no built-in command to do that at the moment. It would require scripting, and as well a very precise definition of the inputs and how the heatmap should look (e.g. how density is defined, if you have different classes of points, what kind of lookup table/opacity, the resolution of the heatmap, approximate size of the image…).

If you can give much more information about what you need and for what purposes, perhaps there are easier ways to get a useful visualization.
