general_subm - construct a generalized subharmonic method.

Calling Sequence

[subm]=general_subm(depth, subpix_per_level, subpix_per_pix)

Parameters

• depth : the number of subharmonic levels to use in the correction (integer).
• subpix_per_level : the number of subpixels to use in each subharmonic level. This number must be odd (integer) and must be greater than subpix_per_pix and less than 3*subpix_per_pix .
• subpix_per_pix : the number of subpixels in each of the original pixels. This number must be odd (integer).
• subm :the output subharmonic methed;

Description

set the generalized subharmonic method. it is a generalization of the methods of subharmonic correction described by Johansson and Gavel,1994, and Lane 1992. lane_subm correspond to (subpix_per_level=3 and subpix_per_pix=3); johansson_gavel_subm correspond to (subpix_per_level=5 and subpix_per_pix=3);

Examples

	subm=general_subm(3,11,5);
