Question 1

How to install HDR Toolbox without a C++ compiler?

Accepted Answer

You can install it, but features like .exr file I/O and bilateral filtering won't work. The README specifies that a C++ compiler is required for these parts, so consider using basic functions or alternative toolboxes if compilation isn't possible.

Question 2

HDR Toolbox vs Python libraries like OpenCV for HDR imaging?

Accepted Answer

HDR Toolbox is specialized for MATLAB/Octave with algorithms from academic research, making it ideal for reproducible studies. OpenCV has broader cross-platform support but may not offer the same depth in HDR-specific algorithms for academic comparisons.

Question 3

How to handle gamma encoding in tone mapped images from HDR Toolbox?

Accepted Answer

Most tone mapping operators output linear values, so you need to apply gamma encoding before visualization or saving, as noted in the README. Exceptions like Mertens et al.'s operator display a warning, so check the output messages.

Question 4

Can HDR Toolbox process RAW images directly?

Accepted Answer

Yes, RAW files are already linear, so for expansion operators, set gammaRemoval to 1.0 as per the README. However, you may need additional tools for RAW conversion, as the toolbox focuses on HDR-specific processing.

Question 5

Is HDR Toolbox compatible with the latest version of Octave?

Accepted Answer

Since it was last updated in 2018, compatibility isn't guaranteed. Check the GitHub repository for issues or test it in your environment, as there's no active maintenance mentioned.

Question 6

How to cite HDR Toolbox in a research paper without using the URL?

Accepted Answer

Reference the book 'Advanced High Dynamic Range Imaging' by Banterle et al. using the provided BibTeX entry in the README. This is mandatory to avoid improper citation practices emphasized by the author.
