Dynamic Adjoin List for Quality Guided Phase Unwrapping

Quality guided phase unwrapping is an effective way to unwrap phases. The adjoin list is an important part in quality guided phase unwrapping. Different implementations of the adjoin list will affect speed and possibly accuracy in the phase unwrapping process. Usually, the adjoin list is very long and hard to operate. A good choice is to split it in to short linked lists, especially when the pixels are equally or near equally distributed in those linked lists. Otherwise, if the quality of pixels is concentrated in a small range, the speedup becomes less obvious. To solve this problem, a dynamic adjoin list is proposed. A fixed length is assigned to each linked list. When there are too many pixels going into one linked list, they will overflow into a lower linked list. The verification is given.
