Parameters
Name | Type | Description |
---|---|---|
src | const CuviImage& | Input 8 bit Gray Scale Image. |
roi | const CuviRect& | Desired region of interest of input image. The function will return features from only that region of the image |
output | CuviPointValue2D<Cuvi32f,Cuvi32f>*& | Output feature list that contains the coordinates & values of features/corners. |
maxFeatures | Cuvi32s& | Desired number of features. If the total features detected in the image or ROI are less than maxFeatures its value is updated to that number |
criteria | const CuviFeaturesCriteria | A structure containing various parameters that affect feature selection behavior |
stream | const CuviStream& | GPU stream ID for execution |
Image Type Support
