Abstract: A video coding mechanism is disclosed. The mechanism includes obtaining a coding tree unit including luma samples and chroma samples. The mechanism partitions the luma samples and the chroma samples according to a common coding tree when a size of a first coding tree node exceeds a threshold. The mechanism also partitions the luma samples with a luma coding sub-tree when a size of a second coding tree node is equal to or less than the threshold. The mechanism also chroma samples with a chroma coding sub-tree when a size of a third coding tree node is equal to or less than the threshold. The luma coding sub-tree contains a different set of split modes than the chroma coding sub-tree.

Abstract: A user permission allocation method includes acquiring currently collected facial feature information of a user; determining a difference degree of the current facial feature information of the user according to the acquired facial feature information of the user and facial feature information included in stored standard sample information; and allocating a user permission to the user according to the determined difference degree. Compared with a manner of using a fixed face threshold, a difference degree of current facial feature information of the user is determined, and when a user permission is allocated to the user, an external factor that affects the collected facial feature information is used as a reference factor, which means that a higher difference degree of the collected facial feature information indicates a lower user permission allocated to the user, so that the user permission of the user is dynamically allocated.
