Semantic Modeling and Pixel Discrimination for Image Manipulation Detection

Algorithm 1

The preprocessing of the multi-resolution fusion (MRF) strategy.

	Input: Bounding boxes in the forgery object detection branch: . : The number of bounding boxes. Pixel-level detection results in pixel-level detection branch: . : The number of results.
	Output: forgery areas:
	assign to AND
	for each do
	if is not null:
	assign to
	else
	assign to
	return
