We present MaeSTrO, a mobile app for image stylization that empowers users to direct, edit and perform a neural style transfer with creative control. The app uses iterative style transfer, multi-style generative and adaptive networks to compute and apply flexible yet comprehensive style models of arbitrary images at run-time. Compared to other mobile applications, MaeSTrO introduces an interactive user interface that empowers users to orchestrate style transfers in a two-stage process for an individual visual expression: first, initial semantic segmentation of a style image can be complemented by on-screen painting to direct sub-styles in a spatially-aware manner. Second, semantic masks can be virtually drawn on top of a content image to adjust neural activations within local image regions, and thus direct the transfer of learned sub-styles. This way, the general feed-forward neural style transfer is evolved towards an interactive tool that is able to consider composition variables and mechanisms of general artwork production, such as color, size and location-based filtering. MaeSTrO additionally enables users to define new styles directly on a device and synthesize high-quality images based on prior segmentations via a service-based implementation of compute-intensive iterative style transfer techniques.
