NAME¶
vistat - report image statistics
SYNOPSIS¶
vistat [
-option ...] [
infile ...] [
outfile]
DESCRIPTION¶
vistat reports the minimum, maximum, mean, and standard deviation of the
pixel values in its input images.
The measurements are reported in the form of a Vista data file containing one
statistics attribute per image measured. Each
statistics
attribute, in turn, contains
min,
max,
mean, and
std_dev attributes reporting individual measurements. It also contains
a
name attribute if the corresponding image has one. Because these
attribute have no binary data associated with them the program's output can be
viewed directly at a terminal.
COMMAND LINE OPTIONS¶
vistat accepts the following options:
- -help
- Prints a message describing options.
- -in infile
- Specifies a Vista data file containing the input
images.
- -out outfile
- Specifies where to write the output statistics as a Vista
data file.
Input and output files can be specified on the command line or allowed to
default to the standard input and output streams.
