Method Detail

process

public void process(T image,
           T template)

Description copied from interface: TemplateMatchingIntensity

Matches the template to the image and computes an intensity image.

Specified by:

process in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Parameters:

image - Input image. Not modified.

template - Template image. Must be equal to or smaller than the input image. Not modified.

evaluate

protected abstract float evaluate(int tl_x,
             int tl_y)

Evaluate the template at the specified location.

Parameters:

tl_x - Template's top left corner x-coordinate

tl_y - Template's top left corner y-coordinate

Returns:

match value with better matches having a more positive value

getIntensity

public boofcv.struct.image.ImageFloat32 getIntensity()

Description copied from interface: TemplateMatchingIntensity

Contains results of template matching. Higher intensity values correspond to a better match. Local matches can be found using NonMaxSuppression. See comment about processing the image border.

Specified by:

getIntensity in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Feature intensity

getOffsetX

public int getOffsetX()

Description copied from interface: TemplateMatchingIntensity

Offset from template's top left corner x-coordinate

Specified by:

getOffsetX in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Offset in pixels

getOffsetY

public int getOffsetY()

Description copied from interface: TemplateMatchingIntensity

Offset from template's top left corner y-coordinate

Specified by:

getOffsetY in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Offset in pixels
