During April 2025, Dimitri Vlachos addressed a bug in the dials/dials repository by refining the spot-finding pipeline to handle mask-aware erosion. He modified the algorithm to exclude masked pixels from erosion checks, treating them as true in the dispersion threshold mask. This adjustment prevented masked pixels from causing incorrect spot erasure and misclassification of strong pixels near masked regions, thereby improving the reliability of spot detection. Dimitri applied his expertise in algorithm development and image processing, implementing the solution in C++. The work demonstrated careful attention to edge cases and contributed to more robust image analysis within the project.
