A new restoration algorithm based on double loops and alternant iterations is proposed to restore the object image effectively from a few frames of turbulence-degraded images. Based on the double loops, the iterative relations for estimating the turbulent point spread function PSF and object image a...

Face location is a difficult problem for face recognition and multiple face location is more challenging. In this paper, two new methods are presented for multiple face location via motion analysis techniques. The first method is based on motion segmentation. The authors introduce a new segmentation...

A novel approach of digital image processing technology is applied to improve SNR of seismic images. At first, we analyze the characters of line-like texture in seismic images, and then a preprocessing method named 2 D tracing horizon filtering is designed. After that, the technology of optical flow...

This paper presents the effects Of acidity and additive pretreatment on the filtering rate and Spirarnycin (SPM) concentration in the filter liquor of SPM fermentation broth. The experimental results show that the SPM peak value in filter liquor iS obtained at pH5.5 with either 0.1% methanal or 0.1%...

A modification of Horn and Schunk's approach is investigated, which leads to a better preservation of flow discontinuities. It improves Horn-Schunk model in three aspects: (1) It replaces the smooth weight coefficient in the energy equation by the variable weight coefficient. (2) It adopts a novel m...
