Abstract: A method for tracking an at least partially occluded object. The method includes recognizing a non-occluded portion of the at least partially occluded object in an input image; generating a simulated image of the at least partially occluded object based on features of the non-occluded portion extracted from the input image; determining first coordinates of the at least partially occluded object in a first coordinate system; and converting the first coordinates of the at least partially occluded object in the first coordinate system into second coordinates in a second coordinate system defined in a display apparatus.

A respective one of the n FPGAs includes a first input circuit and an output circuit and a first process circuit connected between the first input circuit and the output circuit. The first input circuit is configured to receive a respective one first sub-image corresponding to the respective one of the n FPGAs. The n first sub-images are combined to form one frame of initial image. The first process circuit is configured to enhance image-resolution of the respective one first sub-image to obtain a respective one second sub-image and the output circuit is configured to deliver the respective one second sub-image corresponding to the respective one of the n FPGAs to a timing-controller.

Abstract: Provided are a display, a display device, a player, a playing device, and a playing display system. The display comprises at least two first display interfaces, a decode, and at least two data channels. Each first display interface is configured to receive a first image data stream transmitted by a second display interface with which a connection has already been established in a player. The first image data stream includes at least one start data frame and a second image data stream, the start data frame carries a data channel identifier. The decoder is configured to parse each first image data stream, and obtain a data channel corresponding to each second image data stream. Each data channel is configured to receive and output the corresponding second image data stream. The display can ensure that images displayed on a screen will not be ordered, and the operation is simple.

Abstract: Provided is a method for marking a focused pixel. The method includes: in response to marking a focused pixel of a first image based on a focus threshold, adjusting the focus threshold in the case that an adjustment condition is satisfied; marking a focused pixel of a second image based on the adjusted focus threshold. The adjustment condition includes: a focus degree of the first image is less than a target focus degree, and/or, the focus degree of the first image is greater than the target focus degree. Moreover, a similarity between the first image and the second image is greater than a similarity threshold, and a difference between a focus degree of the second image and the target focus degree is less than a difference between the focus degree of the first image and the target focus degree.
