A processing chain for a digital image signal (12) applies a dither pattern (14), having a first spectrum, to the image signal at a point in the processing chain. A further noise pattern (10) is applied to the image signal during the processing chain. The noise pattern (10) has a second spectrum which is configured such that the combination of the first spectrum and second spectrum results in a more continuous spectrum. Another aspect describes a noise pattern (10) which can be used as an offset dither pattern for digital images, especially before colour bit depth reduction. The noise pattern comprises an array of values which are linearly distributed across a range, with each value in the range occurring an equal number of times. Similar values at extreme ends of the range of values are dispersed within the array. The pattern has a Poisson-disk two-dimensional spectral energy distribution. Values are positioned in the array based on distance to similar values in neighbouring repetitions of the array. The array has “magic square” properties.

The invention provides a method for identifying HPLC fingerprints for protecting ginseng of origin, which is characterized by comprising the following steps: A, establishing liquid phase chromatograph fingerprints of the ginseng of origin, namely using the ginseng in the same habitat as a standard, analyzing the ginseng by liquid phase chromatograph and establishing fingerprints; and B, detectinga sample, namely taking a ginseng sample to be detected, detecting the sample under the same conditions as the standard respectively to obtain a spectrogram of the detected sample, and analyzing the fingerprints of the detected sample and the standard by a direct observational method or fingerprints software as qualitative basis. The method has simple pretreatment for fingerprints of the ginseng medicinal material established by adopting the liquid phase chromatograph, multiple peak numbers and better separation degree, therefore, contents of main chemical compositions of the ginseng medicinal material have large difference caused by different growing geographic environments and climates. The HPLC fingerprints of the ginseng can provide reference for distinguishing high-end ginseng health-care products from origin places and non-origin places, and provide reference for establishing fingerprints of other traditional Chinese medicinal materials. The research of methodology shows that all the precision, the stability and the repeatability have better application prospect.
