Method Detail

createDetector

Detector createDetector()

Create the correct Detector.

Returns:

A Detector object.

createDescriptor

Descriptor createDescriptor(java.util.ArrayList<Interest_Point> interest_points)

Create the correct Descriptor.

Parameters:

interest_points - ArrayList of Interest Point on which the descriptor will compute the descriptors.

Returns:

A Descriptor object.

getIntegralImage

Integral_Image getIntegralImage()

Getter for the Integral Image.

Returns:

The Integral Image used by SURF.

setIntegralImage

void setIntegralImage(processing.core.PImage img)

Setter for the Integral Image.

Parameters:

img - PImage that is converted into Integral Image before it's assigned to SURF.

getBalanceValue

float getBalanceValue()

Getter for the Balance Value.

Returns:

The Balance Value. Its default value is 0.9.

setBalanceValue

void setBalanceValue(float balanceValue)

Setter for the Balance Value.

Parameters:

balanceValue - Value used to calculate the Laplacian of Gaussian response.

getThreshold

float getThreshold()

Getter for the threshold.

Returns:

The threshold value.

setThreshold

void setThreshold(float threshold)

Setter for the threshold.

Parameters:

threshold - Value used to filter the Laplacian of Gaussian.

getOctaves

int getOctaves()

Getter for the octaves.

Returns:

Number of octaves computed in SURF.

setOctaves

void setOctaves(int octaves)

Setter for the octaves.

Parameters:

octaves - Number of octaves that you want to compute.
