# XML to JSON converter and polygon shape builder for MASK-RCNN
Annotation builder to use segmentation in Mask_RCNN, even if your annotations are rectangular instead of polygon.
A false masks does not help to be more precise, as it is not providing new information beyond the bounding boxes.
Generates the polygon shape between the four points of the rectangle in order to achieve the polygon shape.

## Requirements
* Python >=3.6

## Usage
* /dataset
    * /train
    * /val
* main.py

````````````$ python main.py````````````

## How should your XML be?

You can check this [xml](dataset/val/IMG_20180413_092050.xml) and see the result [JSON](dataset/val/dataset.json).

```
<annotation>
	<folder>keuring</folder>
	<filename>IMG_20180413_091455.jpg</filename>
	<path>D:\Seafile\Archive\Projects\125 IWAUC\IMG_20180413_091455.jpg</path>
	<source>
		<database>Unknown</database>
	</source>
	<size>
		<width>3968</width>
		<height>2976</height>
		<depth>3</depth>
	</size>
	<segmented>0</segmented>
	<object>
		<name>SD</name>
		<pose>Unspecified</pose>
		<truncated>0</truncated>
		<difficult>0</difficult>
		<bndbox>
			<xmin>2241</xmin>
			<ymin>997</ymin>
			<xmax>2713</xmax>
			<ymax>1325</ymax>
		</bndbox>
	</object>
</annotation>

```

### to achieve this

        "size": 1231831
    }
}
