Effective Clipart Image Vectorization through Direct Optimization of Bezigons
TL;DR: This paper describes a novel method for vectorizing clipart images that directly optimize the bezigons rather than using other intermediate representations and outperforms both the current state-of-the-art method and commonly used commercial software in terms of bezigon quality.
Journal ArticleDOI
PointINS: Point-based Instance Segmentation
TL;DR: PointINS as discussed by the authors decomposes the mask representation learning task into two tractable modules as instance-aware weights and instance-agnostic features, which serve as mask templates in a single point.

Automatic exposure correction of images
TL;DR: In this article, a non-linear function that characterizes the luminance of shadow, mid-tone, and highlight portions of the image is applied to the input image to improve the appearance of underexposed and overexposed regions.
Book ChapterDOI
Normal and feature approximations from noisy point clouds
Tamal K. Dey,Jian Sun +1 more
TL;DR: This work considers the problem of approximating normal and feature sizes of a surface from point cloud data that may be noisy and provides new analyses that lead to new algorithms for practical and reliablenormal and feature approximations.

Dual-phase red eye correction
TL;DR: In this article, a dual-phase approach to red eye correction may prevent overly aggressive or overly conservative red eye reduction by detecting an eye portion in a digital image, which may include the performance of a strong eye correction for the eye portion when the eye part includes a weak red eye.
