A new filter for feature extraction of line pattern texture with application to cancer detection
Jun‐ichi Hasegawa, J.-i. Toriwaki · 2003
Proposes a nonlinear filter for extracting local features of linear texture patterns. This filter calculates at each pixel the degree of local concentration of line patterns based upon a new measure called the concentration index. Basic properties of this measure are shown both theoretically and experimentally, and the filter is applied to detection of cancer lesions from stomach X-ray images.>
