Removing a column defect in image processing
I have a camera which has a couple of minor columns that form a dark line vertically. These are quite common with CCD cameras.
I use CCDstack for calibration. Mostly these just dark subtract out but I am finding sometimes they persist.
Has anyone got some advice about best practice to remove these? CCDstack has a bad pixel map function which I used briefly yesterday and it did not seem very user friendly or effective.
Greg.
