This is a web application for mtgscan, to recognize Magic cards on an image. Try it: http://mtgscan.net.

Requirements

  • docker-compose
  • Azure Computer Vision credentials

I am using Azure free tier, which comes with some limitations:

  • Supported file formats: JPEG, PNG, BMP, PDF, and TIFF
  • The file size of images must be less than 500 MB (4 MB for the free tier) and dimensions at least 50 x 50 pixels and at most 10000 x 10000 pixels.

Usage

At the root of this project:

  • Create a file redis/redis.conf containing requirepass <password>
  • Create a file redis/redis.env containing: REDIS_PASSWORD=<password>
  • Create a file azure.env containing:
AZURE_VISION_KEY=...
AZURE_VISION_ENDPOINT=...

With your Azure Computer Vision credentials

Then:

  • make up
  • Go to http://localhost
  • Load an image or an URL containing magic cards to get the decklist

RESTful API

This application also defines a RESTful API.

Request

GET /api/<url>
Get cards (JSON format) on the image given by url


Example:

curl -G 127.0.0.1:5000/api/https://user-images.githubusercontent.com/49362475/105632710-fa07a180-5e54-11eb-91bb-c4710ef8168f.jpeg
