IMAGE PROCESSING MODULES

MAKESIG

Creates signatures from training sites delineated using COLOR.

EDITSIG

Edits signatures created with MAKESIG.

SIGCOMP

A signature comparison utility.

PIPED

A Parallelepiped classifier.

MINDIST

A Minimum Distance to Means classifier.

MAXLIKE

A Maximum Likelihood classifier.

COMPOSIT

Produces color composite images.

VGACOMP

Produces color composite images for standard VGA systems.

CLUSTER

Performs unsupervised classification.

LANDSAT

Facilitates the downloading of LANDSAT CCT-X data.

RADIANCE

Converts raw values to calibrated radiances for LANDSAT images.

FILTER

Convolves (strictly correlates) an image with a digital filter. Mean, median, mode, edge-enhancement, low-pass, high-pass and user-defined filters are accommodated.

DESTRIPE

Removes band striping due to variable detector output.

COLSPACE

Performs HLS/RGB color space transformations.

PCA

Principal Components Analysis (standardized and unstandardized).

THERMAL

Converts LANDSAT TM Band 6 raw data to blackbody temperatures.

NDVICOMP

Composites images (eg. NDVI) using either a maximum value procedure or a quadratic mean.
