“…For improving the performance of watermarking, a lot of efforts have been done in terms of choosing a suitable quantization feature. Thus, many improved methods based on QIM have been proposed, such as the spread-transform dither modulation (STDM) [8], the logarithmic QIM (LQIM) [9], and the angle QIM (AQIM) method [10]. STDM is as an extension of DM in [7], projection feature is quantized along a random direction, which makes STDM has significant advantages.…”

Abstract. Point cloud models are widely used in industry. It is also faced with increasingly serious copyright protection issues. A new watermarking algorithm of 3D point cloud model using angle quantization index modulation is proposed. At first, a point cloud model is segmented into many patches according to the length of watermark information. Then, for each patch, 1 bit watermark is embedded into by modulating the angle of feature signal. Experiments show that the algorithm is certain robustness against affine transformation, reorder and low intensity of noise.

“…Logarithmic transform and non-uniform quantization step are used in LQIM, which makes it can resist against scaling attack. AQIM first introduced in [10] is an extension of the QIM to angle. The different with traditional QIM method, the angle is quantized instead of quantizing the amplitude values.…”

“…Towards that goal we describe the gradient direction watermarking (GDWM) method (N. Arya et al, 2011). In this method, the watermark bits could be inserted into the angles of vectors of a higher-order gradient of the image, using the angle quantization index modulation (AQIM) method (Ourique et al, 2005). The AQIM has the advantages of QIM watermarking, but it also renders the watermark robustness to amplitude scaling attacks.…”

Trellis coded modulation to improve dirty paper trellis watermarking

Lattice codes and quantization-based techniques have received considerable attention as a method of digital watermarking with side information. However, these algorithms are also recognized to be highly sensitive to common signal processing primitives such as valuemetric scaling, e.g. changes in volume of a song, or re-quantization, e.g. JPEG compression. Hence, it is reasonable to investigate alternative codes which may offer the potential for superior performance. In previous work, we designed a new class of codes, called dirty paper trellis codes (DPTC), which are by construction immune to valuemetric scaling. Although DPTC have shown themselves to be resistant to certain classes attacks, the trellises were generated randomly, thus leading to suboptimal codes. In this paper, Ungerboeck's work on trellis coded modulation (TCM) is exploited to significantly improve the performance of the DPTC. Experimental results show that the resulting trellises significantly outperform the original design.
