The traditional Sobel operator has low edge localization accuracy, poor noise and edge detection continuity. In order to solve these problems, this paper proposes an image fusion algorithm combining ...

Firstly, the edges in the cover image are identified using a suitable edge detection method (i.e., using the canny or sobel algorithm), and then the secret data is embedded inside the edge-detected ...

If the network fails, clone the zbar repository and download the barcode-modelartifacts on a PC, and transfer to the SD card manually, then rerun the setup script. This will download several tools to ...
