Depixelizing Pixel Art

Description

Depixelizing Pixel Art Johannes Kopf Dani Lischinski Microsoft Research The Hebrew University Nearest-neighbor result (original: 40 x 16 pixels) Our result Figure 1: Naive upsampling of pixel art images leads to unsatisfactory results. Our algorithm extracts a smooth, resolution-independent vector representation from the image, which is suitable for high-resolution display devices. (Input image © Nintendo Co., Ltd.).

For this reason, classical pixel art is usu-ally marked by an economy of means, minimalism, and inherent We describe a novel algorithm for extracting a resolution- modesty, which some say is lost in modern computer graphics.
