Publication number: 20240108047Abstract: The invention provides a Probiotic microcapsule and a preparation method thereof, relating to the technical field of Probiotic products. The method includes the following steps: (a) preparing a capsule core containing Probiotics: mixing the capsule core materials including Probiotic powder, microcrystalline cellulose and starch, then adding a hydroxypropyl methylcellulose solution thereinto, while mixing evenly, making the obtained mixture materials into spherical particulate capsule cores by the extrusion spherization method; (b) coating by atomization: coating the microcapsule cores with a coating material solution in a single layer or multiple layers by atomization, getting core-shell microcapsules. The Probiotic microcapsules prepared by the present invention have a large encapsulation, uniform microcapsule particles, controllable particle size, storage-resistance, targetability to intestinal tracts, resistance to gastric acids and high temperature stability.Type: ApplicationFiled: May 31, 2021Publication date: April 4, 2024Inventors: Mingfei YAO, Shengyi HAN, Xin JIN, Weixin HUANG, Jiaojiao XIE, Yanmeng LU, Bona WANG, Ling GAO, Chihui YU, Lanjuan LI

Patent number: 11669978Abstract: The present application provides a method and a device for estimating background motion of infrared image sequences and a storage medium. The method comprises: determining regions to be matched according to the maximum displacement of two adjacent frames of images in background motion, dividing the region to be matched into T sub-regions, and generating M groups of sub-window sets in the sub-regions randomly, and computing the background motion displacement corresponding to these sub-window sets by synchronous mutual information matching, then calculating the background motion displacement between two adjacent frames of images by a potential function voting method according to the background motion displacement corresponding to these sub-window sets. The method in the present application is based on image block matching, and does not depend on feature point extraction, so it has high robustness for background motion estimation of infrared image sequences with few feature points and noise interference.Type: GrantFiled: September 7, 2020Date of Patent: June 6, 2023Assignee: SHENZHEN UNIVERSITYInventors: Jihong Pei, Kaiwen Liao, Weixin Xie, Xuan Yang

Patent number: 10311757Abstract: The invention relates to the technical field of data hiding, in particular to a data hiding method and a data hiding system. An image is used as a data carrier; after secret data is converted into a bit sequence by a sending end, the values of each bit in the bit sequence are hidden in the image; the image hidden with the secret data is obtained and is sent to a receiving end; and the receiving end can extract the hidden secret data from the image according to a corresponding secret key. During data hiding, each square image block can hide two-bit data through inverse number odd-even properties of a pixel gray value sequence of two diagonal lines of each square image block, so that the volume of data hidden in the image is twice of the number of the image blocks split by the image.Type: GrantFiled: February 27, 2017Date of Patent: June 4, 2019Assignee: SHENZHEN UNIVERSITYInventors: Dongning Zhao, Yong Zhang, Weixin Xie, Yanshan Li, Jianping Yu, Jianyong Chen
