Increasing embedding capacity of stego images by exploiting edge pixels in prediction error space
In the field of data concealing, edge detection techniques are frequently employed, particularly for improving image quality and data security. These methods, however, have a lower embedding capacity. In order to take advantage of more edge pixels, many strategies are used nowadays. These schemes ei...
