For Stitching Mode , you can select new optical flow and optical flow to calculate new template according to current
picture .
Optical Flow : basic optical flow algorithm , general stitching speed .
New Optical Flow : an increase of nearly 3 times of stitching speed on original basic optical flow but few scenes can
achieve less stitching e ff ect than basic optical flow . It is suggested to try basic optical flow and compare e ff ects when
you feel dissatisfied about the stitching e ff ect of new optical flow .
Scene - specific Template : speed is fastest but it is not optical flow stitching , so it has limited e ff ect when there ’ s
parallax error and in near distance .
As for Sampling Type , if the camera is still static then three sampling types are not very di ff erent from each other . If
the camera is moving , sampling with slower speed can obtain better image quality which is commonly used in video
stitching .
Blender Type is generally automatically chosen by the computer .
CUDA : if the computer use NVIDIA graphics cards , you have to select NVIDIA CUDA technology to enable hardware
acceleration .
OpenCL : if the computer doesn ’ t use NVIDIA graphics cards , we also provide hardware acceleration through OpenCL .
CPU : non hardware acceleration , pure CPU computing .
