LdrToHdrMerge

Description

Calibrate LDR to HDR response curve from samples

settings

Name	Description
Input	SfM Data File
Response file	Response file
Number of Brackets	Number of exposure brackets per HDR image (0 for automatic detection).
Automatic Nb Brackets	Number of exposure brackets used per HDR image. It is detected automatically from input Viewpoints metadata if “userNbBrackets” is 0, else it is equal to “userNbBrackets”.
Offset Ref Bracket Index	Zero to use the center bracket. +N to use a more exposed bracket or -N to use a less exposed backet.
Bypass	Bypass HDR creation and use the medium bracket as the source for the next steps
Fusion Weight	Weight function used to fuse all LDR images together
Channel Quantization Power	Quantization level like 8 bits or 10 bits.
Highlights Correction	Pixels saturated in all input images have a partial information about their real luminance. We only know that the value should be >= to the standard hdr fusion. This parameter allows to perform a post-processing step to put saturated pixels to a constant value defined by the highlightsMaxLuminance parameter. This parameter is float to enable to weight this correction.
Highlight Target Luminance (Lux)	This is an arbitrary target value (in Lux) used to replace the unknown luminance value of the saturated pixels.
Storage Data Type	Storage image data type
Verbose Level	[‘fatal’, ‘error’, ‘warning’, ‘info’, ‘debug’, ‘trace’]
Output SfMData File	Path to the output sfmdata file
