Transcript and Presenter's Notes

Title: SPATIALDOMAIN TEXTURAL FEATURES


1
SPATIAL-DOMAIN TEXTURAL FEATURES
Co-occurrence Matrix Approaches
  • Spatial Gray Level Depedence Matrix(SGLDM)
  • Construct the co-occurrence matrix

2
Spatial Gray Level Depedence Matrix(SGLDM)
  • Design the measures
  • Energy a measure of homogeneity
  • Inertia a measure of the amount of local
    variations

3
Co-occurrence Matrix Approaches
  • Gray Level Run Length Matrices(GLRLM)
  • Construct the co-occurrence matrix

4
Gray Level Run Length Matrices(GLRLM)
  • Design the measures
  • Long run emphasis
  • Short run emphasis
  • Run length nonuniformity
  • Gray level nonuniformity

5
Roughness of Machined Surfaces
