# Barcode Detection

The Barcode analysis task detects and reads barcodes.

This section describes the parameters that you can use to configure barcode detection.

Configuration Parameter | Description
--- | ---
BarcodeTypes | A comma-separated list of the types of barcodes that might appear in the ingested media.
ImageBinarizeMethod | The method to use to binarize color images and video frames.
Input | The image track to process.
Orientation | The orientation of barcodes in the ingested media.
Region | A region of the frame to restrict processing to.
RegionUnit | The units that the Region parameter uses to specify the size and position of a region.
RestrictToInputRegion | Specifies whether to analyze a region of the input image or video frame that is specified in the input record, instead of the entire image.
SampleInterval | The interval at which frames are selected to be analyzed.
Type | The analysis engine to use. Set this parameter to `Barcode`.

## Output Tracks

Output track | Type | Description | Output1This column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the Input parameter for the output task).
--- | --- | --- | ---
`Data` | BarcodeResult | Contains a record for every frame in which a barcode is detected (multiple records are created when the same barcode appears in consecutive frames). | No
`DataWithSource` | BarcodeResultAndImage | Contains the same information as the `Data` track, but each record also includes the source frame. | No
`Event` | BarcodeEvent | Media Server creates a record in this track when a barcode appears or disappears. | Yes
`Result` | BarcodeResult | Contains a single record for each detected barcode (the same barcode might appear in many consecutive frames). This track only contains the best result from processing a barcode. | Yes
`ResultWithSource` | BarcodeResultAndImage | Contains the same information as the `Result` track, but each record also includes the best source frame. | No

BarcodeResult

Field name | Type | Description
--- | --- | ---
id | UUIDData | A universally unique identifier to identify the barcode (there is one UUID per barcode; records with the same UUID represent the same barcode in different frames)
text | TextData | The information encoded by the barcode
barcodeType | String | The type of the detected barcode.
region | RectangleData | The location of the barcode in the frame

BarcodeResultAndImage

Field name | Type | Description
--- | --- | ---
id | UUIDData | A universally unique identifier to identify the barcode (there is one UUID per barcode; records with the same UUID represent the same barcode in different frames)
text | TextData | The information encoded by the barcode
barcodeType | String | The type of the detected barcode.
region | RectangleData | The location of the barcode in the frame
image | ImageData | The source frame

BarcodeEvent

Field name | Type | Description
--- | --- | ---
id | UUIDData | A universally unique identifier to identify the barcode (there is one UUID per barcode; records with the same UUID represent the same barcode in different frames)
event | TrackingEventData | The type of event (begin/end), and the elapsed time since the barcode appeared.
text | TextData | The information encoded by the barcode
barcodeType | String | The type of the detected barcode.
