DetectDataMatrices_Deprecated
Finds candidates for Data Matrix codes in the input image.
| Name | Type | Description | |
|---|---|---|---|
 |
inImage | Image | Input image |
|
inRoi | Region* | Range of pixels to be processed |
|
inAllowRectangular | Bool | Enables detecting rectangular Data Matrices |
 |
outDataMatrixPositions | Rectangle2DArray | Array of possible positions of Data Matrices |
Applications
Usually followed by a RecognizeDataMatrix filter.
Description
Supported code types: ECC 200 and ECC 000-140.
Around datamatrix must be quiet zone. The minimum quiet zone is equal to the width of a module on all four sides. For applications with moderate to excessive reflected noise in close proximity to the symbol, a quiet zone of 2 to 4 module widths is recommended.
