Moreover, our framework is scalable to the number of images and robust against double JPEG compression as well as the presence of outliers, owning big potential for real-world applications. ...
Such dependencies are encoded under sparse representations which are obtained by solving a LASSO problem with non-negativity constraint. ...
Therefore, we test the robustness of LS-SSC on images coming from 20 cameras of Vision, further compressed using convert tool provided by ImageMagick. ...
