   abstract = {A recurrent problem in the analysis of microscopy images is to quantify the number and size of spots
               on a homogeneous background. Unfortunately, segmenting the individual spots becomes unreliable when
               they are close together, or when the image contains noise and artifacts. On the other hand, manual
               counting and line-scan measurements are prone to bias and too time-consuming to be used in
               high-throughput microscopy. In this work, we derive novel per-pixel measures of spot scale and
               density from Total Variation Flow, a partial differential equation that changes the intensities of
               image regions at a rate inverse to their scale. On simulated, phantom, and real-world data from
               Stimulated Emission Depletion (STED) microscopy, we demonstrate the robustness of our novel method
               relative to a standard segmentation-based approach.}
