ETcVnMatchTemplateWalshOptions

Offers flags to customize template matching based on the Walsh transform.

Syntax

Definition:

enum ETcVnMatchTemplateWalshOptions : ULONG
{
    MTWO_NONE    = 0,
    MTWO_NORMED  = 1,
    MTWO_SKIP_DC = 2
};

Values

Name

Description

MTWO_NONE

Do not use any special options.

MTWO_NORMED

Normalize the elements of the output image to the interval [0, 1.0].

MTWO_SKIP_DC

Skip the DC component during similarity computation. The DC or "direct current" component is the first Walsh component. In contrast to further components, using it for projections captures total pixel intensities and not spatial differences. Therefore, skipping it may improve the robustness to illumination changes.
