1. Modes

1.1. Detect

Not implemeted

1.2. Check

Check if the ratio of the width and height of the object belongs to the range minRatio ~ maxRatio.

1.3. Extract

Not implemeted

2. XML-description

2.1. Common parameters

• Name (string, must be set) attribute unique name
• Type (string, must be "Dimension") attribute type
• Weight (double, default: 1) attribute weight
• Probability (double, default: 0.75) not used in that attibute
• Contour (bool, default: true) not used in that attibute

2.2. Special parameters

• minRatio (double, default: 1.0) lower threshold of the width-to-height ratio
• maxRatio (double, default: 1.0) upper threshold of width-to-height ratio

2.3. Example

Below is an example of using this feature together with a color feature. Note that the detection is performed in a soft mode, which allows you to identify the second object as well, but with a confidence factor of 0.5.

    <Attribute Name="Square" Type="Dimension" minRatio="0.9" maxRatio="1.1"/>
