Image plagiarism; Pattern searching; F-transform; F^s-transform; Image retrieval

The goal of this paper is to introduce a task of image plagiarism detection. More specifically, we propose a method of searching for a plagiarized image in a database. The main requirements for searching in the database are computational speed and success rate. The proposed method is based on the technique of F-transform, particularly F$^{s}$-transform, $s\geq 0$. This technique significantly reduces the domain dimension and therefore, it speeds up the whole process. We present several experiments and measurements which prove the speed and accuracy of our method. We also introduce examples to demonstrate an ability of using this method in many applications.
