Abstract: A method for playing a video includes: playing a first video; displaying a first plot development selection interface in response to end of playing of the first video, wherein the first plot development selection interface includes a first plot prompt message including a plurality of prompt messages, each prompt message corresponding to a plot development direction of the first video; determining a target prompt message, wherein the target prompt message includes the prompt message selected on the first plot development selection interface; and acquiring a second video based on the target prompt message; and playing the second video.

Abstract: An image processing method can include: acquiring an image; determining a feature map of the image based on an image tag classification model, wherein the image tag classification model comprises a plurality of classification tasks; and determining tags corresponding to the feature map based on the classification tasks, wherein each of the tags comprises a probability value.

Abstract: A computing device performs a method of decoding video data by reconstructing a luma block corresponding to a chroma block; searching a sub-group of a plurality of reconstructed neighboring luma samples in a predefined order to identify a maximum luma sample and a minimum luma sample; computing a down-sampled maximum luma sample corresponding to the maximum luma sample; computing a down-sampled minimum luma sample corresponding to the minimum luma sample; generating a linear model using the down-sampled maximum luma sample, the down-sampled minimum luma sample, the first reconstructed chroma sample, and the second reconstructed chroma sample; computing down-sampled luma samples from luma samples of the reconstructed luma block, wherein each down-sampled luma sample corresponds to a chroma sample of the chroma block; and predicting chroma samples of the chroma block by applying the liner model to the corresponding down-sampled luma samples.

Abstract: A method for building a scene comprising: acquiring a first sequence which includes image difference values of video frames captured in a first time period; acquiring a second sequence which includes posture data of an AR device captured in a second time period; acquiring a plurality of third sequences; determining a target time difference, which includes a time difference corresponding to a third sequence with a maximum similarity to the first sequence; and acquiring video frames and posture data for building a scene according to the target time difference, thereby building an AR scene.
