Region

A region to process, instead of processing the whole image or video frame.

Specify the region as a comma-separated list of values in the order: left,top,width,height, followed by the units that you want to use.

You can choose the following units:

Many analysis engines produce records that contain regions, and you might want to process a region that has been identified by another task. To process a region of the image or video that is described in the input track, set Region=Input.

NOTE: Tracking is not supported with Region=Input. In this case each video frame is considered to be an independent image, and Media Server might produce multiple results for the same text.

Required: No

To process the central 50% of the width of the frame, and the entire height of the frame:

To process a region 800 pixels wide by 400 pixels high, 50 pixels from the left and top sides of the image or video:

Region=50,50,800,400 pixels

To process a region described in the input track:
