--- layout: default-layout title: IntermediateResultReceiver - Dynamsoft Capture Vision Android Edition API Reference description: The interface IntermediateResultReceiver includes methods for monitoring the output of intermediate results. keywords: interface, Java, Kotlin needGenerateH3Content: true needAutoGenerateSidebar: true noTitleIndex: true --- # IntermediateResultReceiver The `IntermediateResultReceiver` class is designed as a standardized way for retrieving intermediate results in image processing workflows in the Dynamsoft Capture Vision architecture. By implementing the `CapturedResultReceiver`, you will receive the callback of the various types of captured results, such as pre-detected regions, localized barcodes, etc. Each callback is optional, allowing flexibility and customization based on the needs of the application. ## Definition *Namespace:* com.dynamsoft.cvr *Assembly:* DynamsoftCaptureVisionBundle.aar ```java interface
