        double          *correlation
)

Parameters

*image	Image data structure address
*figure	Figure data structure address
subPixcel	Sub-pixel 0: OFF 1: ON
standardX	Reference coordinate X
standardY	Reference coordinate Y
threshold	Rough search candidate level (0 to 100)
*model	Model data
*positionX	Search coordinate X (measurement result)
*positionY	Search coordinate Y (measurement result)
*angle	Search angle
*correlation	Correlation

Return Value

NORMAL(0): Successful completion

ERROR(-1): Unsuccessful completion

Description

To perform a search, perform the "search image creation for Hough conversion search" and then the "Hough conversion search" to calculate the candidate points.

Next, perform the "normalization CR search" for each candidate point, and output the position having the highest correlation value as the search position.

The search range is specified by a FIGURE structure, which must represent a rectangle figure.
