Frequency Domain Real Time Digital Image Watermarking
The present paper puts forward real time implementation of an algorithm for Watermarking and the results obtained using a Frequency domain approach.. The paper emphasizes an Adaptive Frequency domain watermarking approach in real time, demonstrating robustness against intentional or unintentional attacks on the watermarked image. This is achieved by modifying the middle frequency coefficients. Since the image is analyzed and modified in the frequency domain the changes made are difficult to perceive. The algorithm steps and special consideration regarding the real-time implementation on TI’s TMS320C6711 DSP are presented. Applications of watermarking process in real time are also described.
