Deep Shapely Portraits

Abstract

Figure 1: Given input portrait images with varying poses and expressions (bottom), our approach can automatically generate shapely portraits (top) that are better proportioned, by estimating the best reshaping parameter setting (called shapely degree) using deep learning.

Parametric Reshaping of Portraits in Videos

“…For reducing image distortion after face editing, content-aware image warping becomes a powerful tool in a wide range of editing applications [11] [19] [27]. However, it is challenging to generate continuous and stable deformations across all video frames because the mappings from source to target of consecutive frames are usually inconsistent.…”

“…Xiao et al [27] proposed a reshaping model to generate reshaped portrait images based on an estimated adjusting parameter. We extend this method from reshaping one monocular image to reshaping the whole image sequence.…”

“…However, some control points (mesh vertices) may be occluded (or may emerge) after face deformation and projection, which can significantly affect the warped face shape on the image and cause severe artifacts. Xiao et al [27] utilized the closest grid points to the 2D face contour as control points. While their method works well for a single portrait, it ignores the occluded control points especially when enlarging a face.…”

“…Portrait editing techniques are often utilized to create special portrait effects through face stretch, exaggeration, beautification, etc., such that the resultant portraits are more appealing. Research attention has also been focused on different face retouching methods to edit face colors, textures, styles, and even shapes for portrait images [14] [20] [29] [27]. Compared with portrait images, portrait video editing has been much less explored.…”

Structure-Aware Flow Generation for Human Body Reshaping

“…Portrait photography retouching is widely used in various fields, such as social media, weddings, and advertisements. While automatic face reshaping is well researched [18,24,28,33] and employed in many applications (e.g., Instagram, Tictok), automatic body reshaping, which generally aims to make figure looks more shapely and attractive, is still far from being settled due to the complicated structure and appearance of human bodies. In fact, body reshaping is a troublesome task even for professional artists.…”
