摘要： The present disclosure relates to systems and methods for monitoring control. The systems may obtain one or more monitoring images associated with a monitoring region captured by a monitoring device. The systems may determine whether a target event occurs in the monitoring region based on the one or more monitoring images. In response to determining that the target event occurs in the monitoring region, the systems may obtain a target time period associated with operations of a warning light associated with the monitoring device based on at least one parameter of the monitoring device. The systems may control the operations of the warning light based on the target time period.

摘要： The present disclosure relates to systems and methods for selecting a best facial image of a target human face. The methods may include determining whether a candidate facial image is obtained before a time point in a time period threshold, wherein the candidate facial image has a greatest quality score of the target human face among a plurality of facial images of the target human face; in response to a determination that the candidate facial image is obtained before the time point, determining the candidate facial image as the best facial image of the target human face; and storing the best facial image together with a face ID and the greatest quality score of the target human face in a face log.

摘要： A method for processing an online video stream may include determining a transmission performance of a network for a queue of video frames, wherein each video frame in the queue may be associated with a priority level. The method may also include determining a maximum discarding level based on the transmission performance of the network. The method may further include removing a target video frame of which the associated priority level is lower than or equal to the maximum discarding level from the queue.

摘要： A system and method for determining a dimension of a target. The method includes: determining a camera parameter, the camera parameter including at least one of a focal length, a yaw angle, a roll angle, a pitch angle, or a height of one or more cameras; acquiring a first image and a second image of an target captured by the one or more cameras; generating a first corrected image and a second corrected image by correcting the first image and the second image; determining a parallax between a pixel in the first corrected image and a corresponding pixel in the second corrected image; determining an outline of the target; and determining a dimension of the target based at least in part on the camera parameter, the parallax, and the outline of the target.

摘要： The present provides an affine prediction method and related devices. The method may include: dividing a current coding block into multiple sub-blocks, and determining an initial prediction value of all pixels in each of the sub-blocks; dividing each of the sub-blocks into multiple fraction blocks, wherein at least one of the fraction blocks comprises at least two integer pixels; determining a motion vector difference and a gradient of each of the fraction blocks; calculating a pixel compensation value of each of the fraction blocks based on the motion vector difference value and the gradient; taking the pixel compensation value of each of the fraction blocks as a pixel compensation value of all pixels in each of the fraction blocks; and calculating a final prediction value of each pixel in the current coding block by the initial prediction value of each pixel and the pixel compensation value.

摘要： The present disclosure relates to network connection methods and devices for connecting a terminal device to a network through a network access device. The network access device may include a processor and a connection configuration component. The processor receives a connection request from the terminal device. The processor also authenticates the terminal device based on the connection request, and obtains a verified Internet protocol (IP) address from the connection configuration component. The processor further transmits the verified IP address to the terminal device after the terminal device is authenticated, wherein the terminal device is configured to be connected to the network by using the verified IP address.

摘要： The present disclosure provides a packaging apparatus. The packaging apparatus may include a main body. The main body may include a base plate, a first side plate, and a second side plate. The first side plate and the second side plate may be distributed around the base plate. The packaging apparatus may include an elastic sheet disposed above the base plate. The elastic sheet may include a first fixing part and a second fixing part. The first fixing part and the second fixing part may be connected with the first side plate and the second side plate, respectively. A space may be configured between the base plate and the elastic sheet. When the packaging apparatus is used to package a subject, the first side plate and the second side plate may be folded away from a side of the base plate where the subject is located.
