Description

Fusion is a set of filters that use image pyramids to blend clips together (more commonly used in the creation of HDR images and image stitching).


Requirements


Syntax and Parameters

fuse

Fuse two videos using the mask created by fusemask. As opposed to a normal mix of clips with a mask, fuse will "decompose" frames with a high pass filter, making a stack of different levels of detail. These levels are then blended separately before being recomposed into a final image.

fuse (clip, clip, clip, bool "clamp")


clip   =
Input clip 1.
clip   =
Input clip 2.
clip   =
Mask input clip; black represents clip 1, white represents clip 2.
bool  clamp = false
If true, it keeps each pixel value within the range of the two pixel values from each clip. It won't do anything if the pixel value is already between the two, which it usually is.


fusemask

Creates a binary mask to pass to fuse and can be used to merge two differently exposed images of the same scene [1].

fusemask (clip, clip, clip, float "exp")


clip   =
Input clip 1.
clip   =
Input clip 2.
float  exp = 0.5
exp is a target exposure for the mask, and takes values between 0.0 and 1.0 (with 0.5 as the default).
Some of the "harshness" that is evident in fusion's image can be mitigated slightly by blurring the fusemask.


fusevis

Displays the "decomposed" frames.

fusemask (clip)


clip   =
Input clip.
