## Attributes

| Attribute | Type | Description |
|------- |------|-------------|
| [`frameWindow`](#framewindow) | *NSInteger* | The number of frames to consider for cross-verification. |
| [`minConsistentFrames`](#minconsistentframes) | *NSInteger* | The minimum number of frames that must contain consistent results for verification to succeed. |

### frameWindow

The number of frames to consider for cross-verification. Default value is 5 for barcode decoding.

```
2. 
```swift
var frameWindow: Int { get set }
```

**Value Range**

A positive integer.

### minConsistentFrames
