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 effect than basic optical flow. It is suggested to try basic optical flow and compare effects when
you feel dissatisfied about the stitching effect of new optical flow.
Scene-specific Template: speed is fastest but it is not optical flow stitching, so it has limited effect 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 different 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.
