Detailed Description

Concrete MyListProcessing dedicated to image quality.

Method Documentation

◆ analyzeWithList:darkFrame:flatField:rectangle:method:lowCutoff:highCutoff:()

- (oneway void) analyzeWithList:	(NSData*)	list
darkFrame:	(NSData*)	dark
flatField:	(NSData*)	flat
rectangle:	(MyIntegerRect)	rect
method:	(MyAnalysisMethod)	method
lowCutoff:	(double)	lCutoff
highCutoff:	(double)	hCutoff

Start the analysis of the images in a list.

Parameters

list	An enumerator on the list of images to analyze
dark	The stacked dark frames
flat	The stacked flat fields
rect	The square in which the image is analyzed
lCutoff	Lower frequency cutoff (lower frequencies are not used)
hCutoff	high frequency cutoff (higher frequencies are not used)

After return from this method, the processing starts. For each selected item given by the enumerator, its power spectrum is computed and integrated between lCutoff and hCutoff frequencies.

The image data has the dark frame substracted from it, and is then

divided by the flat field, before Fourier transform.

The integrated value is the evaluated image quality which is sent back to the calling thread by means of the processDidProgress delegate.
