A Subject-Sensitive Perceptual Hash Based on MUM-Net for the Integrity Authentication of High Resolution Remote Sensing Images
2020
ISPRS International Journal of Geo-Information
Preserved Fulltext
To achieve subject-sensitive perceptual hash, we propose a new deep convolutional neural network architecture, named MUM-Net, for extracting robust features of HRRS images. ...
The robust features extracted by MUM-Net are further compressed and encoded to obtain the perceptual hash sequence of HRRS image. ...
The edge features extracted by the method in [13] obviously lack a lot of subtle edge features, which greatly improves the robustness of the algorithm. ...

This hashing method uses a visual attention model called Itti model and Canny operator to construct an image representation, and exploits CS to extract compact features from the representation. ...
Finally, the CS-based compact features are quantized via ordinal measures. L2 norm is used to judge similarity of hashes produced by the proposed hashing method. ...

In this paper, we propose a novel attention-based asymmetric U-Net (AAU-Net) for the subject-sensitive hashing of remote sensing (RS) images. ...
On the basis of AAU-Net, a subject-sensitive hashing algorithm is developed to integrate the features of various bands of RS images. ...
The most prominent performance is that for operations that only change one band, for which the robustness of our algorithm is greatly improved. ...
