```
public T optThreshold(float threshold)
```
    Sets the threshold for prediction accuracy.
    Predictions below the threshold will be dropped.
    
    Parameters:
    
    threshold - the threshold for the prediction accuracy
    
    Returns:
    
    this builder
  - optRescaleSize
```
public T optRescaleSize(double imageWidth,
                        double imageHeight)
```
    Sets the optional rescale size.
    
    Parameters:
    
    imageWidth - the width to rescale images to
    
    imageHeight - the height to rescale images to
    
    Returns:
    
    this builder
  - getImageWidth
```
public double getImageWidth()
```
    Get resized image width.
    
    Returns:
    
    image width
  - getImageHeight
```
public double getImageHeight()
```
    Get resized image height.
    
    Returns:
