In this paper, we propose an adaptive 3D-DCT compression technique, which dynamically determines an optimal size of the video cube based on the motion analysis. The technique cons...

In this paper we present a new descriptor for spatial distribution of motion activity in video sequences. We construct a histogram of areas of distinct regions (or "blobs&quo...

In this paper, we study the security of an image scrambling algorithm based on Space-Filling Curves (SFC). A random SFC is a pixel permutation that changes the scanning order with...
