Bradley Lucier Edges Quotations

I wanted the algorithm to make all the features important to radiologists degrade at the same rate - both the edges of large tumors and the smallest calcium deposits. I tried several approaches and eventually got a balance that seemed reasonable, based on what radiologists tell me they want.

The edges of tumors are where growth occurs, and they tell radiologists whether what they see is a tumor or not. You have to keep all these features intact when you compress the image if it is to be useful.
