Object detection method based on adaptive-parameter-adjustment Gaussian mixture model

InactiveCN105046683AFast convergenceReduce the degree of false detectionImage enhancementImage analysisWeight DecreaseSelf adaptive
The present invention provides an object detection method based on an adaptive-parameter-adjustment Gaussian mixture model. The object detection method comprises the steps of: acquiring edge data of an image sequence; establishing an adaptive-parameter-adjustment Gaussian mixture model for an edge detection sequence, wherein modeling is performed for each pixel point of the edge data through adoption of a combination of k Gaussian distributions, for the successfully matched Gaussian distribution, update rate of the weight decreases along with the increase of the number of frames, and update rate of the mean and variance decreases along with the increase of the historical number of matching of Gaussian distributions, for the unsuccessfully matched Gaussian distribution, parameters are kept unchanged; finally detecting the edge of the image sequence by using the established Gaussian mixture model to obtain a foreground object profile, and filling the foreground object profile to obtain an integral foreground moving object. Compared with a traditional object detection method based on a Gaussian mixture model, the object detection method of the present invention has the beneficial effects that the foreground moving object can be detected more accurately when lights change, and computing speed is raised by 28.574%.

Method for detecting macromolecular substance in reduning injection

The invention belongs to the field of the pharmaceutical detection and discloses a method for detecting a macromolecular substance in a reduning injection. The method for detecting the macromolecular substance in the reduning injection is established by taking thymosin alph1 as a reference and adopting a molecular exclusion chromatography by virtue of the characteristics of a reduning injection producing process. The method comprises the following steps: eluting components in a detected sample according to a molecular weight decreasing sequence, and with a peak appearing earlier than a peak appearance time of a reference substance as the macromolecular substance, and calculating the content of the macromolecular substance by adopting an area normalization method. Through the inspection of repeatability, degree of separation, detection limit, degree of precision, molecular weight logarithm-retention time curve and solution stability, the method for detecting the macromolecular substance in the reduning injection is proved to be simple and convenient to operate, high in sensitivity and good in repeatability, can be used as an quality internal control method of the reduning injection and plays a role in guiding the quality control of traditional Chinese medicine injections.

Method for preserving lotus root with garlic extract and onion extract

The invention relates to a method for preserving a lotus root with garlic extract and onion extract. The method comprises the following steps of: (1) preparing crude garlic extract; (2) preparing crude onion extract; (3) preparing compound preservative: weighing the crude garlic extract and dissolving the crude garlic extract in water, adding the crude onion extract, pullulan and konjac gum in sequence after the crude garlic extract is fully dissolved and stirring the solution uniformly, adjusting the pH of the solution to 4.6-4.8 with citric acid and diluting the solution with water, blending the solution with ultrasonic wave, and cooling the solution to room temperature for standby use, then the compound preservative is prepared; (4) selecting the lotus root raw materials; (5) washing and cutting the lotus root; (6) sterilizing; (7) keeping brittleness; (8) filming; and (9) vacuum packing and refrigerating the lotus root. According to the method for preserving the lotus root with the garlic extract and the onion extract, the garlic extract and the onion extract are used to prepare the compound film preservative serving as the preservative of the lotus root with skins, the compound film preservative has a good preservation effect, and the preservation period can be up to 5 months or above, and thus the problems of browning, hardness decrease and weight decrease in storing the fresh lotus root are solved.

Stove burning-preventing judging method and device, control method and device, and stove

The invention relates to the technical field of intelligent household electrical appliances, and discloses a stove burning-preventing judging method and device, a control method and device and a stove. The stove burning-preventing judging method comprises the steps that the overall specific heat capacity of a cooker is calculated according to the parameters, obtained in real time, including the heat power of the stove, the overall weight of the cooker and the temperature of the cooker, and it is judged that water exists in the cooker when the overall specific heat capacity of the cooker is greater than a preset first specific heat capacity threshold value; and after it is judged that the water exists in the cooker, it is judged that burning of the cooker occurs when the decreasing amount of the overall weight of the cooker in a unit time is smaller than a preset first weight decreasing amount threshold value and the rising amount of the overall temperature of the cooker in the unit time is greater than a preset first temperature rising amount threshold value. Burning of the cooker is judged in time through three-dimensional combination of the heat power of the stove, the overall weight of the cooker and the temperature of the cooker, so that the situation that burning of the cooker fails to be judged in time, and consequentially the stove is inconvenient to use and potential safety hazards exist is avoided.
