Introduction
Image of LorenzoM publicated in Image Processing Challenges - Complete description of a Luminance - Main notes: MaskedStretch, GREYStoration for noise reduction, LocalHistogramEqualization for contrast. Date: Jun 2012.
Processing
ImageCalibration, StarAlignment and ImageIntegration.
Crop.
DynamicBackgroundExtraction. First duplicate the image to see where to put the samples and then use the instance over the original image.
MaskedStretch and HistogramTransformation to clip shadows.
MaskedStretch and HistogramTransformation to clip shadows.
MaskedStretch and HistogramTransformation to clip shadows.
Noise Reduction whit MultiscaleMedianTransform.
StarMask to protect stars and apply HDRMultiscaleTransform twice.
Range mask to protect while noise reduction with GREYCstoration tool in the background.
Invert the mask to protect background and ExponentialTransformation.
Duplicate the image and use as mask to protect lights and apply LocalHistogramEqualization.
Noise reduction once again with ATrousWaveletTransform.
Final image.
