Name |
Description |
|---|---|
|
TCVN_DCO_DEFAULT |
Expects a graylevel image as input and applies the default algorithm (similar to the reference decode algorithm) |
|
TCVN_DCO_BINARY_INPUT |
Expects a binary image as input (all pixels must contain 0 or 255, disables internal preprocessing) |
|
TCVN_DCO_DETECTBLOBS |
Modifies the default algorithm by using blob detection to find the dots (can't be combined with BINARY_INPUT or FILTERCONTOURS) |
|
TCVN_DCO_FILTERCONTOURS |
As a preprocessing step, remove contours connected to the image border and with significantly wrong size (relative to provided fModuleWidth) |
|
TCVN_DCO_REGULAR_COLOR |
Only search for regular color (dark code on light background) |
|
TCVN_DCO_INVERTED_COLOR |
Only search for inverted color (light code on dark background) |
