    Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for generating image mattes for detected objects in digital images without trimap segmentation via a multi-branch neural network. The disclosed system utilizes a first neural network branch of a generative neural network to extract a coarse semantic mask from a digital image. The disclosed system utilizes a second neural network branch of the generative neural network to extract a detail mask based on the coarse semantic mask. Additionally, the disclosed system utilizes a third neural network branch of the generative neural network to fuse the coarse semantic mask and the detail mask to generate an image matte. In one or more embodiments, the disclosed system also utilizes a refinement neural network to generate a final image matte by refining selected portions of the image matte generated by the generative neural network.

  • Publication number: 20250103459
    Abstract: Implementations of the present specification provide methods and apparatuses for training a behavior prediction model. In the implementations of the present specification, a sequence (a behavior sequence of a user) that includes multiple behavior types is split according to behavior types to obtain multiple single-behavior sequences. Time coding is performed on all time points of each of the multiple single-behavior sequences, to obtain multiple single-behavior time sequences corresponding to the multiple single-behavior sequences. Each single-behavior time sequence in the multiple single-behavior time sequences is modeled by using a behavior prediction model, and attention is paid to all time points of each single-behavior time sequence in the multiple single-behavior time sequences, so as to obtain a distribution situation of behaviors corresponding to the multiple single-behavior time sequences in terms of time as predicted by the behavior prediction model.

  • Publication number: 20250069437
    Abstract: The present disclosure describes systems, non-transitory computer-readable media, and methods for utilizing a machine learning model trained to determine subtle pose differentiations to analyze a repository of captured digital images of a particular user to automatically capture digital images portraying the user. For example, the disclosed systems can utilize a convolutional neural network to determine a pose/facial expression similarity metric between a sample digital image from a camera viewfinder stream of a client device and one or more previously captured digital images portraying the user. The disclosed systems can determine that the similarity metric satisfies a similarity threshold, and automatically capture a digital image utilizing a camera device of the client device. Thus, the disclosed systems can automatically and efficiently capture digital images, such as selfies, that accurately match previous digital images portraying a variety of unique facial expressions specific to individual users.
