Design a proprietary app (for iphone, ipad, possibly also for cloud rendering)
We want to be able to let the user take a photo transform it into an adult coloring book page, using filters and patterns (we can provide vector patterns)
Suggested steps within the app to make this happen.
1: convert the image into layers.
Black and white outline layer showing the key shapes (buildings, plants, people, animals).
UI should provide some detail / contrast adjustment sliders.
2: simplify the areas into colors or another way to select a specific area, and fill in a shape / pattern (replace a flattened color layer, with a patterned layer, is one thought.)
3: have a toolkit of simple add on patterns or pre-existing elements (paisley border shape; tree, flower, butterfly, etc.)
4: add text – hand drawn looking fonts that can also be filled with patterns.
5. Export options – vector file or flattened images.
attached is a page created by illustrators but shows the desired outcome.
an existing photo editing app that gets part of the way there is imaengine
