Art Personalization

Create personalized art with AI. Our deep learning model uses Neural Style Transfer to offer arbitrary artistic style transfer, allowing you to extract the style from one image and apply it to another. Most image style transfer models are trained on fixed, pre-defined styles. Ours is designed for flexibility and can accommodate styles not encountered during the training phase.

Endpoint
POST /remix-art
Request Parameters
contentImage
Required
Accepted Values: Image file.
The image you want to serve as a base layer.
styleImage
Required
Accepted Values: Image file.
The image whose style will be applied to the content (base) image.
focusContent
Required
Accepted Values: true or false.
Set to true if you want the result to resemble the base image (contentImage). Setting it to false will result in a more cartoonish image.
Request Example 
curl -H 'Authorization: API_KEY_HERE' \
     -F '[email protected]/Users/porky/pig.jpg' \
     -F '[email protected]/Users/porky/funky.jpg' \
     -F 'focusContent=true' \
     -o '/Users/porky/funky-pig.jpg' \
     https://api-bin.hotpot.ai/remix-art
Response Properties
The resulting image (in a binary format) after transferring style to the content image.
