(a) (b) Figure 1: Illustration of constructing the coupled dictionaries. The red rectangles in (a) and (b) represent the target bounding boxes. The green squares in (a), which are generated by sliding windows outside the target bounding box, correspond to basis patches involved in the background dictionary N. The blue squares in (a) are generated inside the target bounding box in a similar way, which constitute the noisy target dictionary P.
