Abstract

This paper analyses and compares the influence of common error correction codes (BCH, Reed-Solomon with multilevel signaling, binary convolutional codes with Viterbi decoding) in spatial spread spectrum based image and video watermarking. In order to improve the results for video, diversity techniques are used together with channel coding. Three approches for diversity were implemented and compared. Besides a theoretical evaluation of the expected performance of the different codes, the effectiveness of the channel coding and diversity is also assessed under compression (JPEG for still images and MPEG-2 for video sequences).
