public class FillIllegalRowAndColumnFilter

extends Filter

The FillIllegalRowAndColumnFilter is an image processing filter to fill the illegal rows and columns with the median pixel value. In the case of some astronomical images, some pixels from the edges have illegal value, which are too white or too black. They will cause threshold estimation failure or too many noises detection, which leads to fail the star detection or matching process. So in general, every image must be corrected previously by this filter before star detection. The result is stored in the original image.

Field Summary

protected boolean	decrease_enabled True when possible to decrease pixel value.
protected boolean	modified_decreased True when the image is modified, pixel value is decreased.
protected boolean	modified_horizontal True when some rows are modified.
protected boolean	modified_increased True when the image is modified, pixel value is increased.
protected boolean	modified_vertical True when some columns are modified.
