Class 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 .

        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

        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.

                    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
