 High false detection or miss-detection rate? |
 |
Superior pattern matching capability
As shown in the figures below, the POC (Phase-Only-Correction) algorithm results in very sharp peak (right) when matching originally identical images, compared to a normal Fourier transformation result (left).
Horizontal and vertical or rotational displacements of the same images affect the position of the peak and not its height.

|
| Affected by ambient lights? |
|
Not influenced by brightness.
The POC algorithm only uses outlines (- phase component) of the images.
The brightness information (- frequency component) is not used. Therefore,
it is intrinsically not affected by differences in brightness. |

|
| Poor tolerance for signature miss-alignment? |
|
Wide tolerance for signature miss-alignment
POC processes with whole checking-picture. Therefore, even though it loses some part of picture, POC can match patterns with the information of its other parts. |

|
| Influenced by photogravure? |
|
Robust enough to overcome the reflection of photogravure
 |
Robust enough to overcome set-offs
 |
| |
|
Robust enough to overcome ambiguous shapes
 |
Robust enough to overcome miss-alignment

| Complex setup and time-consuming teaching? |
|
Automatic teaching and input with visuals
Trident captures images of the signature as it goes through the camera.
Capture candidate images
Capture up to 8 images
Reference image selection
Trident automatically selects the most suitable image for the reference.
