Problem in reproducing kalantari13`s method on the proposed real world dataset.

[Guanys-dar]

Hello there,

I'm currently facing challenges while attempting to replicate the Kalantari13 method, "Patch-based High Dynamic Range Video," using your provided dataset. While successfully reconstructing sequences labeled "Fire" and "Throwing Towels" from TOG13 dataset, I've encountered issues when working with the dynamic real benchmark dataset.

The error log from matlab console is like:

**********************************

Thank you in advance for your time and assistance!

I'm still encountering an issue as I've come across the same Matlab error. Although adjusting the hyperparameters seemed to resolve the issue, the final results turned out to be quite unsatisfactory. I truly appreciate your assistance in resolving this matter!

I've encountered the same issue too. Have you managed to solve it successfully? Thank you!

Hi, the problem might be the matlab version. Previously I used an old version of Matlab 2016.

Thank you for your response. I tried it, but the error still exists.
