USGS MIPS Destripe Documentation

This program is approximatly equivalent to running a low pass filter, a high pass filter and adding the results together. The major difference is the accuracy. If the individual programs are run, several integer round-offs accure. This program does only one integer round-off when it writes the output dn . The program is capable of running any size boxcar filter for both the low pass and high pass filters. The number of lines and samples for the filters do not have to be equal.

Files

This program requires as input one unsigned 8-bit , signed 16-bit , or 32-bit floating image files. The output file will be created as the same type as the input file. The following information is transferred from the input file to the output file(if appropriate):

Image labels
Mosaic labels
Projection labels
Sonar labels
Navigation file
History file

Parameters

LNL, LNS, LLOW and LHIGH: LNL and LNS are the number of lines and samples in the low pass filter respectively. LLOW is the valid low dn for the low pass filter. All dns below this number will not be used in the calculations for the filter. The defaults for LLOW are 1.0 for unsigned, -32767.0 for signed, and the maximum negative floating point number allowed on the current system for floating point. LHIGH is the valid high dn for the low pass filter. All dns above this number will not be used in the calculations for the filter. The defaults for LHIGH are 254.0 for unsigned, -32766.0 for signed, and the maximum floating point number allowed on the current system for floating point.

HNL, HNS, HLOW and HHIGH: HNL and HNS are the number of lines and samples in the high pass filter respectively. HLOW is the valid low dn for the high pass filter. All dns below this number will not be used in the calculations for the filter. The defaults for HLOW are 1.0 for unsigned, -32767.0 for signed, and the maximum negative floating point number allowed on the current system for floating point. HHIGH is the valid high dn for the high pass filter. All dns above this number will not be used in the calculations for the filter. The defaults for HHIGH are 254.0 for unsigned, -32766.0 for signed, and the maximum floating point number allowed on the current system for floating point.

Uses

This program can be used to apply any size high-pass/low-pass destriping filter to an image.
