摘要
En 中文
In this work, a range image watermarking approach is proposed. First, the image is segmented using active contours; the watermark is then integrated into the resulting contour coordinates. Three active contour methods are used to segment the range image, the obtained segmentation results allow to define the algorithm offering a good compromise between the good segmentation rate and the contour size which constitutes the watermark integration area. The imperceptibility and robustness tests performed show that the proposed scheme offers a good imperceptibility rate as well as a good structural similarity between the original and watermarked image. The watermark is resistant to several attacks commonly used in image watermarking, however, is vulnerable to compression attacks, which is common in spatial integration techniques.
