# Text Detection

Text detection identifies regions in images and video frames that contain text.

Configuration Parameter | Description
--- | ---
Contrast | The minimum contrast level between the text and the background.
DetectionThreshold | The minimum confidence score required for Media Server to detect text.
Input | The image track to process.
MaxCharHeight | The maximum height of a character in the text.
MaxInputQueueLength | Can be used to place a limit on latency.
MinCharHeight | The minimum height of a character in the text.
NumParallel | The maximum number of video frames to analyze simultaneously.
Region | A region of the image or video frame to restrict analysis to.
SampleInterval | The interval at which frames are selected to be analyzed.
Type | The analysis engine to use. Set this parameter to `TextDetection`.

## Output Tracks

The following table describes the tracks that are generated by this engine. The Output 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).

Output track | Description | Output
--- | --- | ---
`Result` | Contains a single record for each detection. The record describes the region that contains the text. | Yes
`ResultWithSource` | The same as the `Result` track, but each record also includes the best source frame. | No

For more information see Text Detection Results or use the action GetExampleRecord.
