improject: Project image along one axis decreasing the

Package: imgtools

Usage

improject infile outfile projaxis

Description

This program projects an image along a chosen axis, producing an image with one fewer dimensions. The axis projected may be either summed or averaged. Processing a 1-dimensional image produces a 1-dimensional image with a single element.

The task appends an image section to each input image name to serve as a template for the output image; this reduces the dimension and establishes appropriate coordinate parameters for the output. For this reason, the input image name must not include an image section.

Parameters

input [file name list]

List of input file names. An image section may not be used with the image names.

output [file name list]

List of output file names, one for each input file.

projaxis = 1 [integer, min=1]

Axis along which to project. If this value exceeds the number of dimensions in an input image, then no operation will be performed.

(average = no) [boolean]

Average the image along the specified axis? If 'average=no', the task will produce a sum along the axis.

(highcut = 0.0) [real]

All values equal to or greater than, 'highcut' will be disregarded, unless 'highcut=lowcut', in which case all points will be used.

(lowcut = 0.0) [real]

All values equal to or less than, 'lowcut' will be disregarded, unless 'highcut=lowcut', in which case all points will be used.

(pixtype = real) [string, allowed values: real | long | int |

short | double]
Data type desired in the output image.

(verbose = yes) [boolean]

Print the file names of each image pair as they are processed?

Examples

1. Project an image along axis 2. If the input image is 2-dimensional, this example will produce a 1-dimensional image by summing the columns of the input image.
