How to identify image spam?
This proposal takes a discriminative classifier learning approach to image modeling, so that image spam can be identified. By analyzing images extracted from a body of spam messages, the researchers have identified four key image properties: color moment, color heterogeneity, conspicuousness and self-similarity.

Can a near-duplicate image-spam detection system detect spam?
The researchers propose a near-duplicate detection system that relies on traditional antispam filtering to whittle inbound mail down to a subset of spam images, then applies multiple image-spam filters to flag all the images that look like the spam caught by traditional means.
