Configure Face Detection for Best Results

To tune the performance of face detection, consider using the following parameters.

Description Default value Example

	Description	Default value	Example
`MinSize`	The smallest size of face (from top to bottom) that Media Server attempts to detect. You can specify the size in pixels or as a percentage of the smallest image dimension (width or height). Setting `MinSize` to smaller values causes face detection to take longer. Setting `MinSize` to a value that is too large is a common cause of face detection failure.	24 pixels	`MinSize=0.15 SizeUnit=percent` For an image of 1024x768 pixels, this value limits face detection to faces that are equal to, or greater than, 115 pixels high.
`ColorAnalysis`	Whether to assess the color of face candidates, in order to reduce false positives.	False	-
