ComfyUI-KJNodes/nodes/image_nodes.py
Sokes a7ce03e735
Update image_nodes.py 
sorted() is needed around os.listdir for proper linux file sorting.

The reason your files are not in order is that os.listdir() returns filenames in an arbitrary order (usually based on how they are stored in the file system's inode table), not alphabetically or numerically.
On Windows, os.listdir sometimes appears sorted due to how NTFS works, but on Ubuntu (Linux), the raw directory listing is almost never sorted by name.
The Fix
You need to sort the list of files before iterating through them.
Change this line:
code
Python
for f in os.listdir(kwargs['video']):
To this:
code
Python
for f in sorted(os.listdir(kwargs['video'])):

color-matcher enables color transfer across images which comes in handy for automatic

to a Multi-Variate Gaussian Distribution (MVGD) transfer in conjunction with classical histogram
matching. As shown below our HM-MVGD-HM compound outperforms existing methods.
