A novel image transmission method based on mosaic image creation and secret image recovery for electric power security

Image transmission is very important for various applications. In order to ensure the security of image transmission, a novel image transmission method based on mosaic image creation and secret image recovery is proposed. The proposed method has two phases: 1) Mosaic image creation. A mosaic image is generated, which includes the fragments of an input secret image with color corrections according to a similarity criterion based on color variations. 2) Secret image recovery. Based on the received signal, the secret image is recovered losslessly from the generated mosaic image. Experimental results show that the proposed method has better feasibility
