histogram_volume

compute and output a histogram of voxel intensities in a MINC volume

histogram_volume volume_file output_filename|none [x|y|z|none] [slice_pos] [filter_ratio] [y_scale]

DESCRIPTION

histogram_volume computes the intensity histogram of a MINC volume and writes it to the specified output file. If none is given as the output filename, the histogram is printed to standard output. An optional slice along the x, y, or z axis at a given position may be selected to compute the histogram for that slice only. The filter_ratio parameter controls the smoothing of the histogram, and y_scale controls the vertical scaling of the output.

OPTIONS

This tool uses positional arguments only. There are no named options.

volume_file

The input MINC volume.

output_filename

The output file for the histogram, or none for standard output.

x|y|z|none

Optional axis for selecting a specific slice. Use none for the whole volume.

slice_pos

The position of the slice along the selected axis.

filter_ratio

Optional smoothing filter ratio for the histogram.

y_scale

Optional vertical scaling factor for the histogram output.

EXAMPLES

Compute the histogram for an entire volume:

histogram_volume volume.mnc histogram.txt

Compute the histogram for a specific z-slice at position 50:

histogram_volume volume.mnc histogram.txt z 50
