Setting up the data can be a bit of an involved process. This document aims to provide a step-by-step procedure for setting the data up correctly.
The root directory for the data is ./data
. The three major portions of the dataset are as follows.
- Full 450 image set of 3 LDR exposures w/ corresponding HDR exposure. Download from here (~3Gb).
- Precomputed HDR images generated by forward passing through a pretrianed HDRCNN model (see reference). Download from here.
- Precomputed HDR images for meta-test generated by forward passing through a pretrianed HDRCNN model (see reference). Download from here.
