Member Function Documentation#

blend()#

void cv::detail::FeatherBlender::blend(
InputOutputArray dst,
InputOutputArray dst_mask )

Python:

cv.detail.FeatherBlender.blend(dst, dst_mask) -> dst, dst_mask

Blends and returns the final pano.

Parameters

  • dst — Final pano

  • dst_mask — Final pano mask

createWeightMaps()#

Rect cv::detail::FeatherBlender::createWeightMaps(
const std::vector< UMat > & masks,
const std::vector< Point > & corners,
std::vector< UMat > & weight_maps )

Python:

cv.detail.FeatherBlender.createWeightMaps(masks, corners, weight_maps) -> retval, weight_maps

Creates weight maps for fixed set of source images by their masks and top-left corners. Final image can be obtained by simple weighting of the source images.

feed()#

void cv::detail::FeatherBlender::feed(
InputArray img,
InputArray mask,
Point tl )

Python:

cv.detail.FeatherBlender.feed(img, mask, tl)

Processes the image.

Parameters

  • img — Source image

  • mask — Source image mask

  • tl — Source image top-left corners

prepare()#

void cv::detail::FeatherBlender::prepare(Rect dst_roi)

Python:

cv.detail.FeatherBlender.prepare(dst_roi)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

setSharpness()#

void cv::detail::FeatherBlender::setSharpness(float val)

Python:

cv.detail.FeatherBlender.setSharpness(val)

sharpness()#

float cv::detail::FeatherBlender::sharpness()

Python:

cv.detail.FeatherBlender.sharpness() -> retval
