Make it easier to see heatmap on image heatmap question

[jxjj]

On colorful pictures, the heatmap is difficult to distinguish from the image. Image filter controls may make it easier to see the response data.

Ideas:

• slider to control image opacity (or heatmap alpha)
• slider to control image grayscale
• side-by-side view to allow compare and contrast

Another option would be to change the heatmap algorithm. It’s much easier to see the regions at scale in a class, once the intensity ramps up.
