Class AlignMTB

java.lang.Object

org.opencv.core.Algorithm

org.opencv.photo.AlignExposures

org.opencv.photo.AlignMTB

public class AlignMTB
extends AlignExposures

This algorithm converts images to median threshold bitmaps (1 for pixels brighter than median luminance and 0 otherwise) and than aligns the resulting bitmaps using bit operations. It is invariant to exposure, so exposure values and camera response are not necessary. In this implementation new image regions are filled with zeros. For more information see CITE: GW03 .

Method Detail

__fromPtr__

public static AlignMTB __fromPtr__(long addr)

calculateShift

public Point calculateShift(Mat img0,
                            Mat img1)

Calculates shift between two images, i. e. how to shift the second image to correspond it with the first.

Parameters:

img0 - first image

img1 - second image

Returns:

automatically generated

computeBitmaps

public void computeBitmaps(Mat img,
                           Mat tb,
                           Mat eb)

Computes median threshold and exclude bitmaps of given image.

Parameters:

img - input image

tb - median threshold bitmap

eb - exclude bitmap

getCut

public boolean getCut()

getExcludeRange

public int getExcludeRange()

getMaxBits

public int getMaxBits()

process

public void process(java.util.List<Mat> src,
                    java.util.List<Mat> dst)

Short version of process, that doesn't take extra arguments.

Parameters:

src - vector of input images

dst - vector of aligned images

process

public void process(java.util.List<Mat> src,
                    java.util.List<Mat> dst,
                    Mat times,
                    Mat response)

Description copied from class: AlignExposures

Aligns images

Overrides:

process in class AlignExposures

Parameters:

src - vector of input images

dst - vector of aligned images

times - vector of exposure time values for each image

response - 256x1 matrix with inverse camera response function for each pixel value, it should have the same number of channels as images.
