Color Image Encryption Based on Deep Learning and Block Embedding

Figure 6

Correlation analysis of related pixels of three groups of experimental diagrams. Image (a) is a color house image, and the correlation analysis diagram of “horizontal, vertical and diagonal” adjacent pixels of (a) from left to right. The image (b) is an encrypted image of (a), and the correlation analysis images of adjacent pixels in three directions of (b) are sequentially from left to right. Image (c) is a color monkey image, and the correlation analysis diagram of adjacent pixels in three directions from left to right is (c). The image (d) is an encrypted image of (c), and the correlation analysis images of adjacent pixels in three directions of (d) are sequentially from left to right. The image (e) is a color map image, and the correlation analysis graphs of adjacent pixels in three directions of (e) are arranged from left to right. Image (f) is the encrypted graph of (e) and is the correlation analysis graph of adjacent pixels in the three directions of (f) from left to right.
