int	Raw = 0
	The raw gray-level image is used to locate the characters.
int	Binarized = 1
	The gray-level image is thresholded before location, thus enhancing contrast between the characters and the foreground.
int	Gradient = 2
	The gradient (edge-detection) of the image is operated on.
int	Laplacian = 3
	The Laplacian of the image is operated on.

Detailed Description

Allowed values for the kind of pre-processing to be applied to the sample image in EasyOCV.

Remarks:

Experience reveals that the best location reliability is achieved by the eVision.ELocationMode.Binarized and eVision.ELocationMode.Gradient modes. Additionally, the eVision.ELocationMode.Gradient mode is not sensitive to the choice of a threshold level. Use of the eVision.ELocationMode.Laplacian mode is not recommended.

Deprecated: Deprecated in version 23.12. Scheduled to be removed in version 27.6.
