Example 1 with DifferenceSpotFilter

use of gdsc.smlm.filters.DifferenceSpotFilter in project GDSC-SMLM by aherbert.

the class FitEngineConfiguration method createSpotFilter.

/**
	 * Create the spot filter for identifying candidate maxima. The actual border, search width and smoothing parameters
	 * can be configured relative to the configured standard deviations or left absolute. The standard deviation is used
	 * to determine the Half-Width at Half-Maximum (HWHM) for each dimension and the parameters set as follows.
	 * 
	 * <pre>
	 * 
	 * int search = (int) Math.ceil(getSearch() * hwhmMax);

	 * // For each filter
	 * double smooth = getSmooth(i) * hwhmMin;
