Abstract: Embodiments of the invention provides a sticker generation method and device, an electronic device, a computer readable storage medium, a computer program product and a computer program. The method comprises: obtaining a material image of a target component on an avatar, the target component being in motion in a sticker comprising the avatar; determining a global position of the target component according to the material image; determining a periodic motion amplitude of the target component in the sticker; generating the sticker according to the material image, the global position, and the periodic motion amplitude. Therefore, a dynamic effect of components in the sticker is achieved, a user does not need to master a specific software and use complex skills to perform vertex layout and movement, and a specific model file does not need to be involved. Thus, the sticker making difficulty is reduced, the sticker making efficiency is improved, and better user experience is achieved.

Abstract: The present disclosure relates to method, apparatus and storage medium for object attribute classification model training. There proposes a method of training a model for object attribute classification, comprising steps of: acquiring binary class attribute data related to a to-be-classified attribute on which an attribute classification task is to be performed, wherein the binary class attribute data includes data indicating whether the to-be-classified attribute is “Yes” or “No” for each of at least one class label; and pre-training the model for object attribute classification based on the binary class attribute data.

Abstract: An image processing method includes acquiring a set of image samples for training an attribute recognition model, wherein the set of image samples includes a first subset of image samples with category labels and a second subset of image samples without category labels; training a sample prediction model using the first subset of image samples, and predicting categories of the image samples in the second subset of image samples using the trained sample prediction model; determining a category distribution of the set of image samples based on the category labels of the first subset of image samples and the predicted categories of the second subset of image samples; and acquiring a new image sample if the determined category distribution does not conform to the expected category distribution, and adding the acquired new image sample to the set of image samples.
