ImageDev

CrossCorrelation2dMsr

Contains the position of the main correlation peak detected in an image.

The object also returns the minimum and maximum correlation scores computed before normalization.

Information about the measurement named measurement can be accessed by using the method measurementInformation() which returns a FieldInformation
Information about the measurement named measurement can be accessed by using the property measurementInformation which returns a FieldInformation
Information about the measurement named measurement can be accessed by using the property measurement_information which returns a FieldInformation

minComputed The minimum correlation score computed before normalization to [-1.0 ; 1.0]. Floating point [slice] COEFFICIENT
maxComputed The maximum correlation score computed before normalization to [-1.0 ; 1.0]. Floating point [slice] COEFFICIENT
matchingPositionX The X coordinate of the best matching position in the output image. Unsigned integer [slice] COORDINATE
matchingPositionY The Y coordinate of the best matching position in the output image. Unsigned integer [slice] COORDINATE

Object methods

Method Description
void toDataFrame() Convert the measurement to an IOLink.DataFrame
One or more "index" columns will be added at the beginning of the dataframe to identify the different elements. For instance:
  • index [label]: The index of the label. This index systematically starts from 0 and is the label value minus 1 when all label values are represented. When there are some missing label values, the corresponding label value cannot be directly deduced from this index.
  • index [time]: The sequence index of a time series or of an image stack.
