# minimumConfidence

The minimum acceptable confidence level for detected rectangles.

## Declaration

```swift
var minimumConfidence: Float
```

## Discussion

Discussion Vision won’t return rectangles with a confidence score lower than the specified minimum. The property’s default value is 0.0, but you can set it to any value in the range [0.0, 1.0]. A value of 0.0 represents no confidence, while 1.0 represents full confidence.
