详细介绍
Image manipulation detection is different from traditional semantic object
detection because it pays more attention to tampering artifacts than to image
content, which suggests that richer features need to be learned. We propose a
two-stream Faster R-CNN network and train it endto- end to detect the tampered
regions given a manipulated image. One of the two streams is an RGB stream
whose purpose is to extract features from the RGB image input to find tampering
artifacts like strong contrast difference, unnatural tampered boundaries, and
so on. The other is a noise stream that leverages the noise features extracted
from a steganalysis rich model filter layer to discover the noise inconsistency
between authentic and tampered regions. We then fuse features from the two
streams through a bilinear pooling layer to further incorporate spatial
co-occurrence of these two modalities. Experiments on four standard image
manipulation datasets demonstrate that our two-stream framework outperforms
each individual stream, and also achieves state-of-the-art performance compared
to alternative methods with robustness to resizing and compression.
