Toward Perceptual Metrics for Video Watermark Evaluation

Assessing and comparing the performance of watermarking algorithms is difficult. The visibility of the watermark is an important aspect in this process. In this paper, we propose two metrics for evaluating the visual impact of video watermarks. Based on several different watermarking algorithms and video sequences, we identify the most prominent impairments as spatial noise and temporal flicker...

An Effective Watermark Embedding Algorithm for High JPEG Compression

Digital watermarking is an important technology that has been widely applied many applications. In this paper, we present an effective embedding watermark method for JPEG image which can resist high compression attack and retain a good image quality. The proposed algorithm consists of three parts which are searching the optimal embedded position, embedded value, and embedded/extracted processin...

A Video Watermark Achievement Algorithm Based on Content of the Video Sub-Region

Resisting collusion attack is one of important performances of video watermark algorithm. This paper presents a novel video watermark algorithm based on the visual features of the host video. The proposed algorithm embeds watermark on the DWT coefficients of sub-regions. The mechanism of JND (just-noticeable distortion) is used to attenuate the embedding strength in the sub-region. Experimental...

Video Object Relevance Metrics for Overall Segmentation Quality Evaluation

Video object segmentation is a task that humans perform efficiently and effectively, but which is difficult for a computer to perform. Since video segmentation plays an important role for many emerging applications, as those enabled by the MPEG-4 and MPEG-7 standards, the ability to assess the segmentation quality in view of the application targets is a relevant task for which a standard, or ev...
