ANSI-C program: reallks.c

NAME
reallks - multilooking of real valued image.

SYNOPSIS
reallks <image> <ML_imageX> <width> [rlks] [azlks] [start] [nlines] [r_start] [nsamp]

<image>	4-byte/value real input file
<ML_imageX>	4-byte/value real output file
<width>	width of complex image
[rlks]	number of range looks (default=1)
[azlks]	number of azimuth looks (default=1)
[start]	starting line (default=1)
[nlines]	number of lines (default: 0=to end of file)
[r_start]	starting range (default=1)
[nsamp]	number of range samples to extract (default: 0=to end of line)

EXAMPLE
reallks 1352_1610.pwr1 1352_1610.pwr1_3 2500 3 3 (generates multilook image (3 looks in range, 3 looks in azimuth) of entire input image)

reallks 1352_1610.pwr1 1352_1610.section.pwr1 2500 1 1 1000 700 500 800 (extracts 700 lines of 800 range pixels (float i.e. 4 byte per pixel) starting at line 1000 and range pixel 500)

INSTALLATION
Source code reallks.c in ./src. For compilation adjust and use Makefile: Executable version reallks in . /bin

AVAILABILITY
Uses ISP type definition file typedef_ISP.h.

DESCRIPTION
reallks generates multilook image of real valued input data file.

In addition to the multilooking reallks allows to select a sub-section of the input image.

OPTIONS
None.
