Findclouds Manual 27
The
"Evaluation BRBG"
shows the final evaluation of the BRBG algorithm -
the calculated cloudiness values. The cloudiness values are based on
counting the pixels of this image.
The value "Cloudiness BRBG" is counted before adjustment of 'Bright Pixel'.
The value "Cloud Bright Pixel" is counted after adjustment of 'Bright Pixel'.
Now bright pixel caused by haze are not counted as cloud any more. This will
cause a reduced cloudiness.
The check box "Use Sunmask" allows to reduce the 'bright pixel area' to the area of the sunmask. The
picture on the right side shows this effect at the bottom of the sun pixel are, because there is a cut off
looking like a semi circle.
