Abstract: A method, apparatus and a system for human body tracking processing, where an apparatus for video collection processing in the system has a built-in intelligent chip, and before uploading video data to a cloud server, the intelligent chip performs a pre-processing on the video data, retains a key image frame and performs a human body detection and a tracking processing on the key image frame by using human body detection tracking algorithm to acquire a first human body detection tracking result. Afterwards, the intelligent chip sends the first human body detection tracking result to the cloud server, so that the cloud server performs a human body re-identification algorithm processing and/or three-dimensional reconstruction algorithm processing on the first human body detection tracking result to acquire a second human body detection tracking result.

Abstract: Embodiments of the present disclosure disclose a method, apparatus and system for controlling a home device. A specific implementation of the method includes: determining whether a current interaction between a user and a virtual control in a pre-built virtual scene meets a preset triggering condition, the virtual control corresponding to the home device being formed in the virtual scene; generating a control signal corresponding to the current interaction, in response to determining that the current interaction meets the preset triggering condition; transmitting the control signal to a control terminal, so that the control terminal controls the home device indicated by the control signal; receiving feedback information corresponding to the control signal transmitted by the control terminal; and rendering and displaying the virtual scene based on the feedback information.

Abstract: An object tracking method, device are provided according to the disclosure. The object tracking method includes: acquiring an object image comprising an object; determining a current image with the object from images captured consecutively, according to the object image; calculating a first pose of the object in the current image using a first algorithm, and calculating a second pose of the object in the current image using a second algorithm, wherein the first algorithm has a faster calculating speed than the second algorithm; determining a pose of the object to be the first pose before a calculation of the second pose is completed; and in a case that the calculation of the second pose is completed, calculating a third pose of the object according to the first pose and the second pose; and determining the pose of the object to be the third pose.

Abstract: An image recognition method and device are provided according to the disclosure. The method includes: obtaining a target image, and extracting at least one first visual feature of the target image; obtaining at least one pending image according to the first visual feature of the target image, and extracting a plurality of second visual features of the target image and the plurality of second visual features of the pending image; for each pending image, forming a plurality of visual feature pairs; and removing an unavailable visual feature pair from the plurality of visual feature pairs, to obtain at least one remaining feature pair; and determining an image similar to the target image from the at least one pending image, according to the at least one remaining feature pair.

Abstract: A method for determining a pose of a camera is provided, the method includes: S101, acquiring an image of a marker; S102, estimating a first pose of the camera according to the image of the marker by a characteristic point method; S103, estimating a second pose of the camera according to the image of the marker by a direct method; and S104, determining the pose of the camera based on the first pose and the second pose.

Abstract: The inventive subject matter relates to the use of L-butylphthalide in the manufacturing of medicaments for the prevention and treatment of cerebral ischemia-induced disease. Cerebral ischemia of the animals or human induces cerebral infarction, neurological deficit, memory disorder, cerebral edema, cerebral apoplexy, metabolic disorder of energy, changes of cerebral blood flow, and the like. The in vivo experiments show that L-butylphthalide can effectively reduce the above-mentioned adverse symptoms induced by cerebral ischemia.
