Data Hiding Scheme Based on Edge Detection and Triangular Mirroring

Interpolation is a commonly used method of hiding data. In this approach, an image is expanded to a larger matrix as a prediction image and then hidden information is placed in the prediction image with high embedding capacity. Jung and Yoo (2009) presented an interpolation approach using neighbor mean interpolation for the prediction value. Lee and Huang (2012) improved Jung and Yoo´s method, and the modified method provides high hidden capacity. In our research, we improve Lee and Huang´s approach to reduce the jagged phenomena based on median edge detector and the triangular mirroring technique. In our experimental results, the proposed method provides efficiency, high quality, and hidden capacity.
