Description |
|---|---|
|
TCVN_MTWO_NONE |
Do not use any special options. |
|
TCVN_MTWO_NORMED |
Normalize the elements of the output image to the interval [0, 1.0]. |
|
TCVN_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. |
