Are there any performance options to improve accuracy or speed?

Yes. The scanner uses a multi-frame result cross filter to enhance accuracy. This filter is enabled by default, which helps reduce recognition errors by cross-verifying results across multiple frames. In MRZScannerViewConfig, you can disable it to increase scanning speed, though this may slightly reduce accuracy.

To disable the cross filter:

const mrzScanner = new Dynamsoft.MRZScanner({
    license: "YOUR_LICENSE_KEY",
    scannerViewConfig: {
        enableMultiFrameCrossFilter: false // default: false
    }
});

💡 Note: Disabling multi-frame cross filtering can make scanning faster, but may increase the risk of recognition errors.
