This paper proposes a saliency detection approach using multi-mapping based on global-local structural information. Firstly, a global-background-suppression(GBS) image and a Lab color space hybrid(CSH) image are obtained through different mapping rules. Secondly, both of them are segmented several times to produce multiple shape images. Thirdly, the above shape images are multiplied with GBS image...
Quality of holographic images reconstructed from digital holographic information system with monochromatic CCD is higher than that from the colorful CCD. We want to use one singular monochromatic CCD to work in the information system of colorful phase-shifting digital holography. After the formulae are deducted and computer programs are designed, we extracted phase shifts, reconstructed the corresponding...
This paper presented a method for recording and reconstructing high-quality digital color holographic images. Digital holography with three different wavelength lasers and a monochrome CCD has been demonstrated. With the phase-shifting of the reference beam, in-line holograms for three wavelengths are recorded successively for derivation of the complex amplitude at each wavelength. The three monochromatic...
Extracting motion layers from videos is an important task for video representation, analysis, and compression. For videos with large interframe motions, motion layer extraction is challenging in two respects: the estimation of large disparity motions and the awareness of large occluded regions. In this paper, we propose an effective method for motion layer extraction under large disparity motions...
In this paper, we propose an efficient scheme to automatically convert existing 2D videos to 3D ones. The proposed method extracts motion information from two consecutive frames to estimate depth map for each of them. In the method, we first develop a region-based Graph cut method to fast and accurately perform motion segmentation, which is robust to large interframe motions. Then, a depth assigning...
