Size

This attribute checks if the object meets the size parameters in the image.

1. Modes

1.1. Detect

Not implemented

1.2. Check

Checks that the object's area is greater than (MinAreaPc * image area) and less than (MaxAreaPc * image area).

1.3. Extract

Not implemented

2. XML-description

2.1. Common parameters

• Name (string, must be set) attribute unique name
• Type (string, must be "Size") attribute type
• Weight (double, default: 1) attribute weight
• Probability (double, default: 0.75) not used for this aatibute
• Contour (bool, default: true) not used for this aatibute

2.2. Special parameters

• MinAreaPc (default: 0) The minimum threshold in percents for the ratio of object area to image area.
• MaxAreaPc (default: 100) The maximum threshold in percents for the ratio of object area to image area.

2.3. Example

The example also contains a description of the color detection attribute, since the size attribute should be paired with attribute in the detection mode.

<AttributeLib>
    
    <Attribute Name="HistColorPink" Type="HistColor" Histogram="histograms/Pink.yaml"/>
    
    <Attribute Name="NotFractal" Type="Size" MinAreaPc="0.5" MaxAreaPc="100"/>

</AttributeLib>

<SimpleObjectBase>  
    
    <SimpleObject Name="PinkSticker" ID="2">              
        <Attribute Type="Detect">HistColorPink</Attribute>  
        <Attribute Type="Check">NotFractal</Attribute>
    </SimpleObject>  
    
</SimpleObjectBase>

In the example of the histogram filtering attribute, you can see that without the size attribute, unwanted noises are present in the image.
