Abstract: The present disclosure provides a method and apparatus for training a semantic segmentation model and a method and apparatus for performing a semantic segmentation on a video. The method comprises: acquiring a training sample set, wherein a training sample in the training sample set comprises at least one sample video stream and a pixel-level annotation result of the sample video stream; modeling a spatiotemporal context between video frames in the sample video stream using an initial semantic segmentation model to obtain a context representation of the sample video stream; calculating a temporal contrastive loss based on the context representation of the sample video stream and the pixel-level annotation result of the sample video stream; and updating a parameter of the initial semantic segmentation model based on the temporal contrastive loss to obtain a trained semantic segmentation model.

Abstract: A method for processing a signal includes: in response to receiving an input feature map of the signal, dividing the input feature map into patches of a plurality of rows and patches of a plurality of columns, in which the input feature map represents features of the signal; selecting a row subset from the plurality of rows and a column subset from the plurality of columns, in which rows in the row subset are at least one row apart from each other, and columns in the column subset are at least one column apart from each other; and obtaining aggregated features by performing self-attention calculation on patches of the row subset and patches of the column subset.
