Notes:
.1. Definition of defected point (bright spot, dark spot): It is identified as a defected point if its
area exceeds 1/2 of a single picture element (R,G,B).
2. Definition of bright spot: It is identified as a bright spot if it is bright in the state of dark field
and its bright size remains unchanged
3. Definition of dark spot: It is identified as a dark spot if it is dark in the state of white field and
its dark size remains unchanged
4.
Definition of two neighboring points: Defects of a group of picture elements(RB,RG,GB).
