Classes and parameters JSON description

Sets of classes and parameters of objects labelled on an image is customizable.

While configuring the job, user of the system should should modify the JSON file with classes and parameters of objects labelled on images, in order to specify those classes and parameters he/she is interested in.

The structure of that JSON file is described below.

{
  "classes":
  [
    "class 0",
    "class 1",
    "class 2",
    "class N"
  ],

  //OPTIONAL
  "colors":
  {
    "class 0":"#468966",
    "class 1":"#FFF0A5",
    "class 2":"#FFB03B",
    "class N":"#B64926"
  },  

  "parameters":
  [
    {
      "type": "boolean",
      "name": "is occluded"
    },

    {
      "type": "string",
      "name": "phone number",
      "prefix": "+7"
    },

    {
      "type": "select",
      "name": "select an option",
      "options":
      [
        "option 1 name",
        "option 2 name",
        "option N name"
      ]
    }
  ]
}

Configuring class colors

To make annotating easier we provide the ability to specify colors for each class. To do so, create a new dict in classesandparams.json and specify a color for each class in HEX format. Note that providing colors is optional and if no colors were supplied, the default color scheme will be used. The default color scheme can be located in color_scheme.js file.

The example configuration is shown above and marked with OPTIONAL comment.
