Backend

We developed our backend with the following technologies:

  • Python
  • Django
  • Serpy

Structure

Most of the application code is within the api folder. In the following I will explain where you can find what.

im2txt

im2txt is a image captioning package which allows us to generate caption on demand.

management

This exposes all the commands that you can use via the command line.

migrations

Every time we change our models we have to migrate the database. We use djangos migration feature to create migration files to migrate without the headaches.

models

Here are the actual data types. If you want to figure out how a photo works or how faces are connected to persons, than this is your folder.

places365

places365 generates scene classifications for a given image. It genereate the tags you see when you open the photo details in the UI.

Here you can find the code which allows us to search semantically for images like “trees in a valley”.

views

Here you can find our API implemented. This will get split up further as time goes on.

All the other classes you see, don’t fit into the folder structure for now.
