Download and install Python for Windows: https://www.python.org/ftp/python/3.5.2/python-3.5.2-amd64.exe + +4.

Create file `obj.names` in the directory `build\darknet\x64\data\`, with objects names - each in new line + +3.

Put image-files (.jpg) of your objects in the directory `build\darknet\x64\data\obj\` + +5. Create `.txt`-file for each `.jpg`-image-file - with the same name, but with `.txt`-extension, and put to file: object number and object coordinates on this image, for each object in new line: `<object-class> <x> <y> <width> <height>` + + Where: + * `<object-class>` - integer number of object from `0` to `(classes-1)` + * `<x> <y> <width> <height>` - float values relative to width and height of image, it can be equal from 0.0 to 1.0 + * atention: `<x> <y>` - are center of rectangle (are not top-left corner) + + For example for `img1.jpg` you should create `img1.txt` containing: + + ``` + 1 0.716797 0.395833 0.216406 0.147222 + 0 0.687109 0.379167 0.255469 0.158333 + 1 0.420312 0.395833 0.140625 0.166667 + ``` + +6.
