Image enhancement method in automatic fingerprint identification technology

InactiveCN102629316AImprove the definition of linesAdapting to the requirements of enhanced processingCharacter and pattern recognitionPattern recognitionGaussian function
The invention relates to a fingerprint identification method and a system thereof, relates to a fingerprint image enhancement method and discloses an image enhancement method in an automatic fingerprint identification technology. The method is characterized by: firstly, constructing a two-dimensional sine filter which has a consistent with a fingerprint; then, using a two-dimensional Gaussian function to carry out modulation on the two-dimensional sine filter so as to obtain a Gaussian modulation two-dimensional sine filter; and carrying out correction on the Gaussian modulation two-dimensional sine filter, constructing the filter which accords with an actual need of fingerprint image processing; using a frequency parameter and a direction parameter of each fingerprint image area to construct an appropriate enhancement template of the Gaussian modulation two-dimensional sine filter; finally carrying out convolution operation on the corresponding Gaussian modulation two-dimensional sine filter template and the corresponding fingerprint image area, carrying out enhancement processing on the fingerprint image, and carrying out normalization processing on an enhancement result so as to obtain the final enhancement fingerprint image.

Natural plant essence repairing mask and preparation method thereof

The invention relates to a natural plant essence repairing mask. The natural plant essence repairing mask consists of powder and a solvent, and is used for oral administration and external application, that is, the powder is orally taken, and the powder and the solvent are mixed for external application. The raw material powder comprises the following components in parts by weight: 0.2-2 part of tremella powder, 0.2-2 part of lily powder, 0.2-2 part of honey freeze-dried powder, 0.1-0.12 part of coix seed powder, 0.1-1.5 part of Chinese yam powder, 0.1-1.5 part of sweet almond powder, 0.1-1.5part of whey protein powder, 0.1-1 part of royal jelly freeze-dried powder and 0.01-0.1 part of trehalose. The preparation method of the natural plant essence repairing mask comprises the following steps: uniformly mixing the raw material components, and performing sub-packaging. The selected raw material powder adopts natural raw material components which have high biological activity and are rich in various nutritional ingredients, and can increase cell activity, improve and eliminate dull yellow and rough skin, restore skin elasticity and homogenize skin color when being externally used. The effects of tonifying lung, moistening lung, strengthening lung and clearing lung can be achieved during oral administration, and harm caused by air pollution is eliminated. The preparation method ofthe natural plant essence repairing mask is simple and easy to implement, low in cost and suitable for mass production.

Injection gel containing controllably degradable polyester microspheres

ActiveCN114209887AImprove subcutaneous volumeRepair WrinklesCosmetic preparationsToilet preparationsSodium hyaluronatePolyester
The invention provides injection gel containing controllably degradable polyester microspheres. The injection gel is prepared from cross-linked sodium hyaluronate gel, non-cross-linked sodium hyaluronate gel, polyester microspheres wrapped by mixed fatty glyceride and a balanced salt solution. The polyester microspheres are separated from water by means of wrapping and hydrophobic effects of the mixed fatty glyceride, and the problem that a polyester material is easy to degrade in gel is solved. Meanwhile, the mixed fatty glyceride has the characteristic of low melting point (the melting point is 33-39 DEG C), and after the product is injected into a human body, the mixed fatty glyceride is melted, separated and released to wrap the polyester microspheres under the action of the body temperature of the human body, so that the microspheres can be degraded in the human body, and the characteristic of controllable degradation is realized. When the prepared gel for injection is not used, the microspheres contained in the gel can be stored at normal temperature in a non-degradation or micro-degradation mode, after the gel is injected and used, a wrinkle area is filled with the microspheres, the microspheres are released, subcutaneous collagen growth is stimulated along with in-vivo degradation of the microspheres, and the effect of improving skin wrinkles in a long-acting mode is achieved.
