CosmicAI: Generating Sky Images Through Content-Based Search, Flexible Composition, and Work Sharing

Abstract

We propose a novel system, called CosmicAI, for providing an intuitive and efficient way to synthesize 2D sky images. The system utilizes a collection of high-quality proprietary sky part images for backgrounds, clouds, and the moon, and allows the users to generate their own sky images effectively through attribute-based retrieval of these sky parts images and their flexible layout and natural composition based on a new cloud extraction algorithm and an original filter for partly-overlapping pixels. Its one click search and active composition play an important role for realizing rapid image synthesis. Moreover, CosmicAI is capable of collecting via the Internet and searching for composite works. This function promotes group works by giving incentives to users with unclear design motives for generating a wide variety of sky images.
