-islandsplitmethod: (default value: 'scipylabel') Several image processing algorithms have been created to separate bunches that appear on the same image. See here for some algorithm details.
- 'scipylabelscipyLabel' calls the scipy label function to label contiguous regions. this is fast, but requires a region of no signal (after de-noising) between the regions.
- 'autothreshold' tries to separate the islands by automatically finding thresholds that separate them. this is the recommended mode for multi-bunch operation.
- 'contourlabelcontourLabel' tries to adjust a threshold until two large groups are found, grouping together pixels using an opencv contour method. there are two parameters ('ratio1/ratio2') that are settable for the contour method that determine
