摘要：
To eliminate speckle noise no image with perfect character of orientation from non-contact measurement based on conoscopic holography, an improved method of mean curve diffusion filter is proposed for analyzing different orientational filters, which filters noise according to curvature of the iamge plane. So it can preserve edge information effectively, and a linearly changing factor is introduced to make filter process faster. Experimental results show that this method can get better filter effect and satisfy real-time measurement of conoscopic holography system.
