RaiMan proposed the following answer:
If you are talking about SikuliX features (supposing you use them), then the complete image handling is done in Java with Java features.
OpenCV  is used for image search (match-template) and Tesseract is used for OCR in images.

If you say:
images are no longer useable for search 

... then this means, that images you see on the screen now and the older
shot to search with no longer have the same pixel content.

So you have to analyze, what exactly has changed.

Take one example, make a new shot and compare it in an image viewer
resized, so you can see the pixels.

Only if there is some systematic change, that could be compensated
programmatically, then there is a chance.

Otherwise you have to recapture the images.

The FindFailed options to recapture the not found images while the
script is running might help, to reduce the effort.
