Project Title

A web application to extract face and object annotations from videos using computer vision algorithms for face/object detection/recognition

Prerequisites

On a GNU/Linux Debian Stretch machine install

• python 2.7
• docker
• docker-compose

Installing

Clone git repository on your machine. On a console run:

git clone https://github.com/fedjo/orca.git

Upload a face database

Upload a zip file containing the faces you want to find on videos.

• URL

  /model

• Method:

  POST

• Data Params

  model=[path of the zipfile]

• Success Response:

  • Code: 200
    Content:{ "people" : [ "Obama", "Trump" ] }

• Sample Call:

  $.ajax({url: "/model",dataType: "json",type : "POST",data: newBinaryData('/path/to/file')success : function(r){console.log(r);}});

List all face databases

List all face databases that the recognizer has been trained with.

• URL

  /model

• Method:

  GET

• Success Response:

  • Code: 200
    Content:[ "actors.yml", "students.yml"" ]

• Sample Call:

  $.ajax({url: "/model",dataType: "json",type : "GET",success : function(r){console.log(r);}});

Annotation Process

Call the annotation process to generate automatic annotations.

• URL

  /annotate

• Method:

  POST

• Data Params
