Classification of image edge blocks by orthogonalprojection
Mahmoud K. Quweider, James B. Farison · Electronics Letters · 1997
The authors present a new image edge block classification method using a set of orthhogonal projection filters, accomplished by choosing the index of the filter that gives the maximum output magnitude. Coded monochromatic images with 0.625 – 0.813 bits/pixel are shown to preserve their quality and edge integrity, as seen by subjective and objective measures.
