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.

process

public void process(T image,
                    T template,
                    T mask)

Description copied from interface: TemplateMatchingIntensity

Matches the template with a mask 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.

mask - Mask that identifies how translucent pixels. 0 = 100% transparent and all values above increase its importance. Typical values are 0 to 255 for integer images and 0.0 to 1.0 for floating point.

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

evaluateMask

protected abstract float evaluateMask(int tl_x,
                                      int tl_y)

Evaluate the masked 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.GrayF32 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

getBorderX0

public int getBorderX0()

Description copied from interface: TemplateMatchingIntensity

Thickness of border along the image left side (lower extent)

Specified by:

getBorderX0 in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Border in pixels

getBorderY0

public int getBorderY0()

Description copied from interface: TemplateMatchingIntensity

Thickness of border along the image top (lower extent)

Specified by:

getBorderY0 in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Border in pixels

getBorderX1

public int getBorderX1()

Description copied from interface: TemplateMatchingIntensity

Thickness of border along the image right side (upper extent)

Specified by:

getBorderX1 in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Border in pixels

getBorderY1

public int getBorderY1()

Description copied from interface: TemplateMatchingIntensity

Thickness of border along the image bottom (upper extent)

Specified by:

getBorderY1 in interface TemplateMatchingIntensity<T extends boofcv.struct.image.ImageBase>

Returns:

Border in pixels
