Examine a set of detected squares for match with known markers.

Performs the intermediate marker-detection stage of taking detected squares in a processed image, and matching the interior of these squares against known marker templates, or extracting matrix codes from the interior of the square.

Parameters

image	Image in which squares were detected.
xsize	Horizontal dimension of image, in pixels.
ysize	Vertical dimension of image, in pixels.
pixelFormat	Format of pixels in image. See <AR/config.h> for values.
markerInfo2	Pointer to an array of ARMarkerInfo2 structures holding information on detected squares which are candidates for marker matching.
marker2_num	Size of markerInfo2 array.
pattHandle	Handle to loaded patterns for template matching against detected squares.
imageProcMode	Indicates whether square detection was performed treating the image as a frame or a field.
pattDetectMode	Whether to perform color/mono template matching, matrix code detection, or both.
arParamLTf	Lookup table for the camera parameters for the optical source from which the image was acquired. See arParamLTCreate.
pattRatio	A value between 0.0 and 1.0, representing the proportion of the marker width which constitutes the pattern. In earlier versions, this value was fixed at 0.5.
markerInfo	Output: Pointer to an array of ARMarkerInfo structures holding information on successful matches.
marker_num	Output: Size of markerInfo array.
matrixCodeType	When matrix code pattern detection mode is active, indicates the type of matrix code to detect.

Returns

0 in case of no error, or -1 otherwise.
