    Abstract: Methods and systems are disclosed for performing operations for applying augmented reality elements to a person depicted in an image. The operations include receiving an image that includes data representing a depiction of a person; generating a segmentation of the data representing the person depicted in the image; extracting a portion of the image corresponding to the segmentation of the data representing the person depicted in the image; applying a machine learning model to the portion of the image to predict a surface normal tensor for the data representing the depiction of the person, the surface normal tensor representing surface normals of each pixel within the portion of the image; and applying one or more augmented reality (AR) elements to the image based on the surface normal tensor.

    Abstract: Methods and systems are disclosed for performing operations comprising: receiving a video that includes a depiction of a real-world object; generating a three-dimensional (3D) body mesh associated with the real-world object that tracks movement of the real-world object across frames of the video; determining UV positions of the real-world object depicted in the video to obtain pixel values associated with the UV positions; generating an external mesh and associated augmented reality (AR) element representing the real-world object based on the pixel values associated with the UV positions; deforming the external mesh based on changes to the 3D body mesh and a deformation parameter; and modifying the video to replace the real-world object with the AR element based on the deformed external mesh.

    Abstract: Methods and systems are disclosed for performing operations for deforming an external mesh. The operations comprise receiving a video that includes a depiction of a real-world object. The operations comprise generating a three-dimensional (3D) body mesh associated with the real-world object that tracks movement of the real-world object across frames of the video. The operations comprise obtaining an external mesh associated with an Augmented-Reality (AR) element. The operations comprise accessing a plurality of deformation attributes associated with the external mesh, each attribute corresponding to a different deformation model. The operations comprise separately deforming, based on respective deformation models, a first portion of the external mesh and a second portion of the external mesh. The operations comprise modifying the video to include a display of the AR element based on the separately deformed first and second portions of the external mesh.
