Search() [1/4]

static SearchResult Search ( Image  image, Image  template, double  density  )

static

Find the best correlation match of the template in the image with sub-pixel accuracy. The amount of sub pixel accuracy that may be achieved depends on the size of the template.

Parameters

image	image in which to look for correlation matches
template	template with which to look for correlation matches
density	scan density with which to look for correlation matches

Returns

best result that was detected (SearchResult.Empty if none was found)

Exceptions

ArgumentNullException	If image or template are null
ObjectDisposedException	If image or template has already been disposed
ArgumentOutOfRangeException	If the parameter value is invalid or the density exceeds the range [0...1].

Search() [2/4]

static SearchResult Search ( Image  image, Image  template, double  density, Area2D  aoi  )

static

aoi	area in which to look for correlation matches

Returns

best result that was detected (SearchResult.Empty if none was found)

Exceptions

ArgumentNullException	If image or template are null
ObjectDisposedException	If image or template has already been disposed
ArgumentOutOfRangeException	If the parameter value is invalid or the density exceeds the range [0...1].

Search() [3/4]

static SearchResult Search ( ImagePlane  plane, ImagePlane  template, double  density  )

static

Find the best correlation match of the template in the plane with sub-pixel accuracy. The amount of sub pixel accuracy that may be achieved depends on the size of the template.

Parameters

plane	image plane in which to look for correlation matches
template	template with which to look for correlation matches
density	scan density with which to look for correlation matches

Returns

best result that was detected (SearchResult.Empty if none was found)

Exceptions

ArgumentNullException	If plane or template are null
ObjectDisposedException	If plane or template has already been disposed

Search() [4/4]

static SearchResult Search ( ImagePlane  plane, ImagePlane  template, double  density, Area2D  aoi  )

static

Find the best correlation match of the template in the plane with sub-pixel accuracy. The amount of sub pixel accuracy that may be achieved depends on the size of the template.

Parameters

template	template with which to look for correlation matches
density	scan density with which to look for correlation matches
aoi	area in which to look for correlation matches

Returns

best result that was detected (SearchResult.Empty if none was found)

Exceptions

ArgumentNullException	If the Parent of plane or template is null
ObjectDisposedException	If the Parent of plane or template has already been disposed
ArgumentOutOfRangeException	If the density exceeds the range [0...1].

SearchAll() [1/4]

static SearchResult[] SearchAll ( Image  image, Image  template, double  density, Area2D  aoi, double  threshold, int  radius  )

static
