PTmasker1

Usage

Overview

PTmasker computes stitching masks. It implements the ability to increase depth-of-field by stacking images.

Options

-p prefix

Prefix for output files (defaults to masked%4d).

-e feather

Size of the feather (defaults to zero).

-f

Force processing (do not stop on warnings).

-x

Delete source files (use with care).

-q

Quiet run.

-h

Output help summary.

-z

Enable Extended depth of field.

-m

Focus estimation mask type.

0 hard-edged masks, mutually exclusive

1 hard-edged masks, stack of nested masks

2 blended masks, stack of nested masks

2 is default and strongly recommended: This option includes a smoothing computation that seems to help a lot.

-w integer

Focus estimation window size. Only available if -z.

Recommended value is 0.51001114526f image width, e.g. 4 pixels for an 800-pixel image.

Computation cost for focus estimation increases proportional to N^2. Defaults to w4.

-s integer

Smoothing window size. Only available if -z.

Recommended value is 0.50f image width, e.g. 4 pixels for an 800-pixel image.

Computation cost for focus estimation increases proportional to N^2. Defaults to w4.
