Fusing Multiple Images with Enfuse 4.0-753b534c819d

Enfuse

This manual is for Enfuse (version 4.0-753b534c819d, 1 August 2010), a program to merge different exposures of the same scene to produce an image that looks much like a tonemapped image.

Overview

Workflow

Invocation

• Common Options: General options
• Extended Options: Memory control and others
• Fusion Options: Image fusion control
• Expert Options: Local contrast and local entropy selection configuration
• Option Delimiters: How to separate options' arguments

Weighting Functions

• Weighting Pixels: General concept of weighting pixels
• Exposure Weighting: Weighting by exposure
• Saturation Weighting: Weighting by saturation
• Local Contrast Weighting: Weighting by local contrast
• Local Entropy Weighting: Weighting by local entropy

Weighting Algorithms

• Weighted Average: Enfuse's default weighting algorithm
• Disabling Averaging: ``Super Trouper'' weighting for focus stacks

Local Contrast Weighting

• Standard Deviation: Standard deviation (SDev) in a square of pixels
• Laplacian of Gaussian: LoG, a second derivative method
• Blend SDev and LoG: Mix both methods
• Scaling and Choice of Mode: How parameters do not scale; neither does mode
