![]() You might notice that tapping the screen doesn’t do anything right now, but before you can get to the Vision part of this tutorial, you need to display an image on the screen. If you build and run now, you’ll see instructions for tapping the screen and a functional settings icon. The starter project includes some extensions, model files, and the UI. Sounds like fun, right? Exactly… art should be fun! Getting StartedĬlick the Download Materials button at the top or bottom of this tutorial. Simplify the contours to create an artistic effect.Tweak settings to get different contours.Create requests to perform contour detection.In this tutorial, you’ll learn how to use the Vision framework to: And that’s what this tutorial is all about! For instance, if you detected all of the contours in an image, you might have some cool material to make an artsy-looking drawing of the image. You can even use computer vision algorithms to create exciting filters and effects for images and photos. ![]() Different sets of algorithms change how the final output looks and feels. Most digital photography is about post-processing the pixels that come from a sensor. Think about how Apple has been pushing the limit on computational photography. Getting creative with the tools available to you can significantly affect the output. So how can you, a developer, use code to create art? Maybe it’s not how you code but rather what you choose to do with it. Sure, developers can be opinionated at times, but how a computer interprets your code is very much not a matter of opinion.
