On: Image Compression with Neural Networks

[acd]

Is there any image compression that uses Eigenfaces? Using the fact your face may look similar to someone else face.

What if you use uniqueness and eigenface look up table for compression?

Not an expert in this, but you would need a lot of eigenfaces to capture the variance (i.e. a lot of upfront cost storing all the eigenimages). It might be good for something that is very standardized (e.g passport photos where everyone is in the same position) but otherwise I think there probably is too much variance to keep the number of eigenimages to a reasonable number.
