Unable to perform assignment #1

Open afong3 opened 5 months ago

afong3 commented 5 months ago

I've followed the README's 'Usage Steps' and get an error after about 10s of runtime for the start_stitch.m script. The script kills and returns 'Unable to perform assignment because the left and right sides have a different number of elements.'

The 'dataset_dir' was set to be a valid directory on my device which has .jpg files stored with identical file sizes in grid format of 3 rows x 16 columns. I would love to see if FRMIS would be able to stitch together our images but I don't have the Matlab experience to debug this.

I've since downloaded the Level 1 SCC dataset and it ran without problems. My dataset does not have all the metadata that the .tif files from SCC has. Namely pixel size, height, and width. I am working on encoding my .jpg's as tiff files and adding this information to the metadata. Although the 'img_type' field in the matlab script is very misleading considering there is no documentation on supported filetypes.

Having guidance on the necessary metadata fields or supported filetypes would be greatly appreciated.

Hi @afong3, I am trying to run FRMIS and I am running into the same issue. Have you figured out what is missing from your image files or what needs to be changed in the Matlab code? Any help would be appreciated.

Hi @PSilling, unfortunately we didn't explore much more of FRMIS because of this problem. We were on a tight schedule and already stretching the use case of FRMIS to stitch wood samples. Instead of FRMIS we ended up using Stitch2D with Python. This was the only tool that was able to stitch our images from what we tried. Feel free to reach out if you're interested in how we implemented it.

I see, that is unfortunate, but I completely understand. I might also switch from FRMIS to a different tool due to tight schedule. Either way, thank you for the quick response and for the recommendation, it's much appreciated!
