Computer Vision Networks. Developing digital visual methods for social and medium research.
The potentialities of computer vision for digital networks and online images studies are valuable assets for digital research but still unknown or little explored. Against this background, this project interrogates vision APIs for social and medium research, while developing forms of technical-methodological creation with digital methods. To that end, methods recipes and research software will be created to facilitate the study of online images through networks. Based on situated case studies, the project proposes ways of building and reading networks of images and correspondent descriptions or sites of circulation across the Web. Crucial here, I argue, is a technical understanding on Vision APIs infrastructure combined with the practice of digital methods and visual network exploration. The project attempts to minimise the difficulties found in the use of computer vision for research purposes. The expected results include replicable research models for using this approach to different objects of study.
