Client Appl Search & Retrieval
Summary This component generates a texture descriptor for a homogeneously textured Image/Region for Search and Retrieval using texture features. The descriptor components are the average and the standard deviation of the image together with the energies and the energy deviations of Gabor filtered reponse of each (predefined) fequency channels.
Strong Points Statistically very precise description of homogeneously textured region.
Limitations Relatively large in size (32 components for the basic layer and 62 components for the enhanced layer).
Known Problems NONE
Parameters HomogeneousTexture.par: dummy parameter file to show the usage
/* additional parameters*/
layer : The layer information of the descriptor
0:base-layer, 32 components
1:full-layer, 62 components
option: Matching option for client
n: normal matching
r:rotation invariant matching
s:scale invariant matching
rs:rotation and scale invariant matchin
