vul_sequence_filename_map Class Reference

#include <vul_sequence_filename_map.h>

List of all members.

Detailed Description

Maps sequence frame indices to filenames.

vul_sequence_filename_map maps sequence frame indices to filenames. It also performs some disk probing functions to discover the image extension, directories and sequence template if not specified by the user.

The template can have any of the following forms : "pgm/img.%03d.pgm,0:5:100", "pgm/img.####.pgm", "img.###.pgm", "img.###,5:1:20", "img.%02d,:5:" (you get the idea..) If the image directory and/or filename extension are not specified they are automagically determined by probing the current directory for likely candidates.

The vector of indices specifies the mapping from sequence frame-index to filename-index. If not specified, the image directory is probed to determine the sequence start/end frames.
