Proposed based on wavelet transform of digital image watermark embedding and extraction algorithms, according to the algorithm designed and implemented with an intuitive visual significance of the binary image and extract the hidden watermark, and Of the algorithm of filtering, noise, geometry and other attacks on experiments. To quantitatively validate the robustness of the algorithm, using Normalized...
In this paper, a wavelet analysis is based on digital image watermark embedding and extraction algorithms, according to the algorithm designed and implemented in the visual sense with intuitive binary image watermark in the gray image of the hidden and extraction, and carried out a simulation experiment. The experimental results show that the algorithm research paper is feasible, from the visual point...
The traditional binary phase-only matched filter (BPOF) has a great loss of information and difficulty in recognition in hybrid photoelectric image matching system, and ternary amplitude-phase filter (TAPF) is proposed here to try to solve these problems. We carried out computer simulation of infrared scene matching and compared the performances of TAPF, BPOF and ACMF. Experiment results show that...
