Abstract: Systems and methods are provided for generating custom garment patterns for producing clothing sized to fit any newly input human body representation. A set of reference sample bodies may be selected for which custom designed garment patterns are then obtained. Once reference patterns are obtained, a custom garment pattern for a particular new body may be automatically created by blending two or more of the reference patterns. For example, the neighboring reference bodies to the new body may be identified within a low-dimensional embedding space, and interpolation of garment parameters for the previously designed garment patterns for these reference bodies may be performed to produce a custom garment pattern.

Abstract: According to an embodiment, a method includes estimating, based at least in part on a first location of a bounding box for a foot in a first frame of a sequence of frames and a second location of the bounding box in a second frame of the sequence of frames, a smoothing transformation that characterizes a movement of the foot in the sequence of frames and smoothing, based at least in part on the smoothing transformation, a movement of a structure of the foot from a first location of the structure in the first frame to a second location of the structure in the second frame. The method also includes superimposing a model of a shoe onto the foot in the sequence of frames based at least in part on the smoothed movement.

Abstract: Described are systems and methods directed to generation of a personalized three-dimensional (“3D”) body model of a body, such as a human body, based on two-dimensional (“2D”) images of that body and the generation and presentation of predicted personalized 3D body models of the body when one or more body measurements (e.g., body fat, body weight, muscle mass) are changed. For example, a user may provide a target body measurement value and the implementations will generate one or more predicted personalized 3D body models representative of a predicted appearance of the body with the target body measurement value.

Abstract: Systems and methods are provided for improved 3D garment draping simulation. A garment pattern may be obtained that includes a number of flat, 2D garment panels designated to be connected at seam lines. Triangulated versions of each of the 2D garment panels may then be positioned in 3D virtual space relative to a 3D model of a human body, such that one or more annotated points on each triangulated garment panel are aligned with a corresponding labelled point or region on the 3D body. A warped 3D garment mesh may then be generated by repeatedly applying geometric manipulations to the triangulated garment panels to connect their corresponding seam lines without causing collisions between the triangulated garment panels and the 3D body. This warped 3D garment may then be provided as input to a physics-based draping simulator.
