createtrainingmrcstack.py when run also generates what is known as a tile configuration file. This file contains the locations where the tiles were extracted from the parent images.

Format of configuration file. Values in capital letters and in <BLAH BLAH> are labels described later:

[DEFAULT]
imagedir = <PATH TO DIRECTORY WHERE IMAGES RESIDE> 

[<IMAGE FILE NAME>]
<NUMBER IE 1> = <LEFT>,<UPPER>,<RIGHT>,<LOWER>
<NUMBER IE 2> = <LEFT>,<UPPER>,<RIGHT>,<LOWER>

[<ANOTHER IMAGE FILE NAME>]
<NUMBER IE 3> = <LEFT>,<UPPER>,<RIGHT>,<LOWER>
<NUMBER IE 4> = <LEFT>,<UPPER>,<RIGHT>,<LOWER>
Descriptions of <BLAH BLAH> values above:

  • <PATH TO DIRECTORY WHERE IMAGES RESIDE> -- This is the full path to the directory where the images are located. It is assumed all images are same size. Example: (/tmp/images or /home/bob/images)

  • <IMAGE FILE NAME> and <ANOTHER IMAGE FILE NAME> are the names of the image files and denote sections in the configuration file. All <NUMBER IE #> below pertain to this image. Example: (foo.png)

  • <LEFT>,<UPPER>,<RIGHT>,<LOWER> Pixel coordinates of the tile in the parent image representing a box.
