Customization

1. Configuration

To customize the directories used, edit the PHP file inc/configuration.php

<?php
# Image path to be used in the HTML client
$IMAGE_WEB_DIR = "data/images";

# Image path for internal PHP use
$IMAGE_ROOT_DIR  = "../data/images";
$ANNOTATIONS_DIR = "../data/annotations";

# Collection name 
$COLLECTION_NAME = "collection_01";

# Not annotated image 80% to be presented to user
$ratio_new_old = 80;
?>

2. Images

Images to be annotated are located in data/images/collection_01/part_1 and data/images/collection_01/part_2

3. List of classes

The list of classes can be customized in the file resources/list_of_tags.json

[
	{"name": "Long Beak Bird", "icon": "resources/tag_examples/long_beak.jpg"},
	{"name": "Eagle", "icon": "resources/tag_examples/eagle.jpg"},
	{"name": "Parrot", "icon": "resources/tag_examples/parrot.jpg"},	
	{"name": "Baby Bird", "icon": "resources/tag_examples/baby_bird.jpg"}
]

The result is quite cool !

4. Annotations Target directory

Each image will generate one XML file in the directory data/annotations

Output as Pascal VOC xml files

This format is a standard and can be easily read from Tensorflow Object Detection API
