In order to overcome the large computing of Non-Local (NL) means for image de-noise, a new method of FANL(Fuzzy Adaptive Non Local) means de-noise is proposed in this paper. It is proposed that the noise variance is estimated from noise image. And the optimism parameter is estimated by variance and noise image standard deviation. The optimism parameter is acquired from fuzzy control algorithm to a...
To find a new quantitative determination method for low-index ingredients in traditional Chinese medicine, we study the rationality of 5mg/mL casein plate violet circle method using Luo Yu Tong capsule as experimental material. Test results shows: the correlation coefficient R is 0.9989, precision RSD is 2.11%, repeatability (RSD) is 3.66%, the recovery is 98.5%, detection stability is not less than...
In this paper, a novel gray-level image watermarking algorithm based on local feature region and Singular Value Decomposition (SVD) is presented for copyright protection. A new way which utilizes the Binary Coded Decimal (BCD) method and encodes the gray-level secret information into bit string is used. It employs the singular values of SVD to extract the most valuable features of the watermark image...
