Abnormal behavior identification method based on contour

InactiveCN101464952AReduce intensityCharacter and pattern recognitionCharacteristic sequenceAnomalous behavior
The invention discloses a method for recognizing aberrant behaviors based on contours. The method is characterized in that the detection and the tracking of moving targets are primarily performed for the image sequences collected by a camera so as to extract target contours; then spatial information of the moving targets in each frame is indicated by utilizing R transformation; then the spatial information is rearranged and combined as characteristic vectors of behavior analysis and the characteristic dimension reduction is performed by adopting principal component analysis; finally the transformation relation of the contour sequences with spatial information in the time is indicated by utilizing a hidden Markov model, and all the behaviors can be indicated with respective parameters of the hidden Markov model. In the recognition process, the characteristic sequences of new behaviors are compared with the storage parameters, and the behaviors best matched are selected upon the maximum likelihood principle. Therefore, the method for recognizing aberrant behaviors has an important significance of automatic analysis for intelligent visual monitoring, so that time, places and characters of occurrence events in the scene can be known without assistance of the people; moreover, the method for recognizing aberrant behaviors also can be used for video retrieval so as to assist the people to seek for the interesting events in the video frequency.

Bast fiber separating device

InactiveCN102586894AStable separationReduce intensityMechanical fibre separationEngineeringFiber
The invention discloses a bast fiber separating device, which comprises grinding rollers and kneading rollers positioned behind the grinding rollers. The outer diameter of each grinding roller is equal to that of each kneading roller, the grinding rollers and the kneading rollers are respectively vertically aligned pairwise, and the rollers in each pair are the same in structure and are engaged with each other. Semicircular grid bars on the surfaces of the grinding rollers are used for evenly grinding sticks of hemp stems, so that the sticks are primarily separated from bast fibers. Spirally arranged racks on the surfaces of the kneading rollers are used for kneading while further grinding the hemp stems, so that the bast fibers are thoroughly separated from the sticks. As the kneading rollers and the grinding rollers have linear speed difference, both longitudinal acting force and transverse acting force are applied to the hemp stems, and skins and the sticks of the hemp stems are separated more evenly while the bast fibers are not damaged. In addition, gaps among the semicircular grid bars and gaps among the flat racks are all arc grooves, namely contact surfaces of the hemp stems and each pair of kneading rollers are smooth arc surfaces, the strength of the bast fibers cannot be reduced, and the bast fibers cannot be lost.

Liquid crystal display panel and liquid crystal display device

The invention is applicable to the technical field of liquid crystal display and provides a liquid crystal display panel and a liquid crystal display device, wherein the liquid crystal display panel comprises an active component array substrate with an upper surface and a lower surface, a colorful filtering substrate arranged in the opposite direction of the active component array substrate, a liquid crystal layer arranged between the upper surface of the active component array substrate and the colorful filtering substrate, and a grating arranged on the lower surface of the active component array substrate. In the embodiment of the invention, the lower surface of the active component array substrate is provided with the grating, therefore, when a backlight module emits a light beam, the light beam can achieve the grating by an optical film; furthermore, the grating can lead the light source blocked by the lightproof/light-absorbing grating in the prior art to become an available light source by passing the clearance of the gratings again after multiple reflection of the grating with the reflective characteristic, thus improving the brilliance when the liquid crystal display panel displays stereoscopic images and reducing the intensity of the backlight module simultaneously.

Regeneration method of coal liquefied oil hydrogenation deactivated catalyst

The invention provides a regeneration method of a coal liquefied oil hydrogenation deactivated catalyst, which comprises: (a) a catalyst filling phase in which the hydrogenation catalyst to be regenerated is filled into a rotary kiln regeneration device (1); (b) a low temperature scorching phase in which heated process air with a low oxygen content is injected at a temperature of 200 DEG C-350 DEG C, wherein the oxygen content of the process air is 1-10 vol%, and the gas-agent ratio during the catalyst regeneration reaction is 2000-5000/h (vol/vol); (c) a transition phase in which the regeneration temperature of the catalyst is firstly increased after the temperature increase of a bed layer in the low temperature scorching phase is not more than 5 DEG C and the content of CO2 and SO2 in the air is less than 0.05 wt%, then the oxygen concentration of the process air is increased; (d) a high temperature scorching phase in which high temperature scorching of the catalyst is carried out at 450 DEG C-470 DEG C when the temperature increase of the bed layer in the transition phase is within 5 DEG C and the content of CO2 and SO2 in the air is less than 0.05 wt%; (e) a purification phase. The method can effectively prevent catalyst deactivation due to heat generated during combustion of a lot of C and S in the deactivated catalyst, reduce equipment investment, and reduce catalyst regeneration cost.
