Abstract: A method and an apparatus for compressing a content name are provided. In the method, a controller constructs a content name tree according to content names in a content database, where a first node of the content name tree stores a first-level prefix of a content name in the content database, and an Nth-level node of the content name tree stores prefixes of first N levels of the content name; and then the controller compresses a content name stored in the Mth-level node into a first content name stored in a father node of the Mth-level node when determining that the content name stored in each Mth-level node in the content name tree is corresponding to a first network node in a network. Thus, compression of a content name in a content name database is achieved, and space occupied by the content name is saved.

Abstract: An image processing method, a related device, and a computer storage medium are provided. The method includes: obtaining a feature intensity image corresponding to a training image, where an intensity value of a pixel in the feature intensity image is used to indicate importance of the pixel for recognizing the training image, and resolution of the training image is the same as resolution of the feature intensity image; and occluding, based on the feature intensity image, a to-be-occluded region in the training image by using a preset window, to obtain a new image, where the to-be-occluded region includes a to-be-occluded pixel, and the new image is used to update an image recognition model. According to the embodiments of the present application, a prior-art problem that a model has low accuracy and relatively poor generalization performance because of limited training data can be resolved.
