Teaching People and Machines How to Enhance Images

Procedural tasks such as following a recipe or editing an image are very common. They require a person to execute a sequence of operations (e.g. chop onions, or sharpen the image). People commonly use step-by-step tutorials to learn these tasks. We focus on the domain of photo manipulations and have developed tools and techniques to help people learn, compare and automate photo manipulation procedures. We present a demonstration-based system for automatically generating succinct step-by-step visual tutorials of photo manipulations. Our tutorials are quick to generate. Moreover, users are faster and make fewer errors with our tutorials compared to book and video tutorials. We also demonstrate a new interface that allows learners to browse, analyze and compare large collections (i.e. thousands) of photo manipulation tutorials based on their command-level structure. Finally, we present a framework for generating content-adaptive macros (programs) that can transfer complex photo manipulation procedures to new target images. Together these tools allow people to learn, compare and automate procedural knowledge.
