Detailed Description#

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 GW03 .

Member Function Documentation#

calculateShift()#

Point cv::AlignMTB::calculateShift(
InputArray img0,
InputArray img1 )

Python:

cv.AlignMTB.calculateShift(img0, img1) -> retval

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

computeBitmaps()#

void cv::AlignMTB::computeBitmaps(
InputArray img,
OutputArray tb,
OutputArray eb )

Python:

cv.AlignMTB.computeBitmaps(img[, tb[, eb]]) -> tb, eb

Computes median threshold and exclude bitmaps of given image.

Parameters

img — input image
tb — median threshold bitmap
eb — exclude bitmap

getCut()#

bool cv::AlignMTB::getCut()

Python:

cv.AlignMTB.getCut() -> retval

getExcludeRange()#

int cv::AlignMTB::getExcludeRange()

Python:

cv.AlignMTB.getExcludeRange() -> retval

getMaxBits()#

int cv::AlignMTB::getMaxBits()

Python:

cv.AlignMTB.getMaxBits() -> retval

process()#

void cv::AlignMTB::process(
InputArrayOfArrays src,
std::vector< Mat > & dst )

Python:

cv.AlignMTB.process(src, dst, times, response)

cv.AlignMTB.process(src, dst)

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

Parameters

src — vector of input images
dst — vector of aligned images

process()#

void cv::AlignMTB::process(
InputArrayOfArrays src,
std::vector< Mat > & dst,
InputArray times,
InputArray response )

Python:

cv.AlignMTB.process(src, dst, times, response)

cv.AlignMTB.process(src, dst)

Aligns images.

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.

setCut()#

void cv::AlignMTB::setCut(bool value)

Python:

cv.AlignMTB.setCut(value)

setExcludeRange()#

void cv::AlignMTB::setExcludeRange(int exclude_range)

Python:

cv.AlignMTB.setExcludeRange(exclude_range)

setMaxBits()#

void cv::AlignMTB::setMaxBits(int max_bits)

Python:

cv.AlignMTB.setMaxBits(max_bits)

shiftMat()#

void cv::AlignMTB::shiftMat(
InputArray src,
OutputArray dst,
const Point shift )

Python:

cv.AlignMTB.shiftMat(src, shift[, dst]) -> dst

Helper function, that shift Mat filling new regions with zeros.

Parameters

src — input image
dst — result image
shift — shift value
