Embodiment 1

[0037] according to figure 1 The steps shown are to calculate the spectral similarity value of a certain Luzhou-flavor liquor:

[0038] (1). Selection of liquor samples and map data:

[0039] Select 20 samples of this type of liquor, and the composition map data of each sample includes 43 common liquor map data (mg / L) that can obtain, and described map data includes acetaldehyde (z 1 ), ethyl formate (z 2 ), ethyl acetate (z 3 ), acetal (z 4 ), tert-amyl alcohol (z 5 ), ethyl butyrate (z 6 ), sec-butanol (z 7 ), n-propanol (z 8 ), butyl acetate (z 9 ), isobutanol (z 10 ), isoamyl acetate (z 11 ), ethyl valerate (z 12 ), n-butanol (z 13 ), n-pentyl acetate (z 14 ), methyl butanol (z 15 ), isoamyl alcohol (z 16 ), ethyl caproate (z 17 ), n-pentanol (z 18 ), ethyl heptanoate (z 19 ), ethyl lactate (z 20 ), n-hexanol (z 21 ), ethyl octanoate (z 22 ), furfural (z 23 ), acetic acid (z 24 ), ethyl nonanoate (z 25 ), propionic acid (z 26 ), butyric acid (z 27...

Abstract

The invention discloses an atlas similarity calculation method based on baijiu features. The method comprises the following steps: eliminating a weight difference caused by the large atlas data scaledifference of a baijiu sample through the normalization preprocessing, screening out atlas data with the large contribution rate of the baijiu features through the principal component analysis, and determining a weight value of the atlas data participating in the similarity calculation according to the size of the contribution rate of the atlas data. While the similarity of two baijiu atlases in the same type is calculated, only the screened atlas data is selected, and the corresponding weight value is substituted in a similarity formula to obtain a similarity value. The similarity value obtained by using the method is capable of eliminating the adverse effect to the similarity value caused by the low contribution rate or irrelevant atlas data, adequately considering the differences of thecontribution rates to the baijiu features caused by the different feature components, and more accurately reflecting the similarity level of the baijiu features, so the objective evaluation to baijiuis more accurate.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for detecting abnormal events in surveillance video. Background technique [0002] The raw materials, koji, distiller's mother and environment used in the brewing process of liquor are not the same, even the same batch of liquor may have great differences in flavor formation. At present, my country has determined that there are more than ten types of liquor aromas, such as strong aroma, sauce aroma, light aroma, rice aroma, sesame aroma, phoenix aroma, medicinal aroma, special aroma and so on. Liquor is a mixture of multiple chemical components, except for 98% water and ethanol, it also includes trace components such as alcohols, esters, acids, amino acids, ethers, and aldehydes. Trace components account for about 2%, but there are many types. With the advancement of science and technology, more than 300 trace components that determine the aroma style of liquor...
