Module: | OpenCV |
---|
BRISK keypoint detector and descriptor extractor.
Name | Type | Range | Description | |
---|---|---|---|---|
inImage | Image | Input image | ||
inMask | Region* | |||
inThreshold | Integer | 0 - | AGAST detection threshold score | |
inOctaves | Integer | 0 - | Detection octaves. Use 0 to do single scale. | |
inRadius | RealArray* | Defines the radii (in pixels) where the samples around a keypoint are taken (for keypoint scale 1). | ||
inNumber | IntegerArray* | Defines the number of sampling points on the sampling circle. Must be the same size as inRadius. | ||
inMax | Real | 0.0 - | Threshold for the short pairings used for descriptor formation (in pixels for keypoint scale 1). | |
inMin | Real | 0.0 - | Threshold for the long pairings used for orientation determination (in pixels for keypoint scale 1). | |
inPatternScale | Real | 0.0 - | Apply this scale to the pattern used for sampling the neighbourhood of a keypoint. | |
outKeyPoints | AnnotatedPoint2DArray | Annotated x value mean class id and y mean angle | ||
outDescriptors | Matrix | Matrix contained features values and class id. |
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Input arrays must have equal size in cvDetectFeature2D_BRISK. |
DomainError | inRadius and inNumber must be set together in cvDetectFeature2D_BRISK. |
Complexity Level
This filter is available on Basic Complexity Level.
