Name
minmaxTexture - Min-Max filters for texture measurement
Syntax
minmaxTexture [-t <title>] <inimage> <outimage>
<texdim_1> .. <texdim_n>
Description
minmaxTexture uses multi-scale MIN-MAX operators in order
to characterize the local texure on different geometric
scales (texdim_1,...., texdim_n).
minmaxTexture creates an image where the number of
bands equals the number of window sizes
(texdim_1,..., texdim_n) used. These bands can be used to
find a signature for the input image.
In band no. 1, we identify all structures less than texdim1
using window (texdim_1 x texdim_1). In the same way, using
window (texdim_n x texdim_n), all structures less
than texdim_n have been identified from the input image
and shown in band no. n.
texdim_n (where n=3,5,..) are window sizes used to
characterize the local texture on different geometric scales
texdim_1 < texdim_2 <...< texdim_n.
Options
-
-t title
- Specify a title for the output image
Restrictions
inimage must have bands with pixel type unsigned byte.
