This paper proposes a Binary Particle Swarm Optimization (BPSO) and scene change based watermarking algorithm where BPSO is used to identify the robust pixels into which the watermark is to be inserted. Different watermarks are inserted into frames belonging to different scenes identified using a scene change detection algorithm. The watermarked video is obtained by inserting the singular values of Discrete Wavelet Transform (DWT) + Discrete Fourier Transform (DFT) sub-bands of the watermark into the singular values of Discrete Wavelet Transform + Discrete Fourier Transform sub-bands of video frames. Experimental results show the promising performance of the proposed algorithm for watermarking. Peak Signal to Noise Ratio (PSNR) values for the watermarked video in the range of 45 dB to 50 dB and maximum correlation of 0.9998 are achieved.
