Typedefs¶

typedef std::shared_ptr<TPixelLabelInfoBase> Ptr

Used in CObservation3DRangeScan::pixelLabels.

Methods¶

virtual void setSize(const int NROWS, const int NCOLS) = 0

Resizes the matrix pixelLabels to the given size, setting all bitfields to zero (that is, all pixels are assigned NONE category).

virtual void setLabel(const int row, const int col, uint8_t label_idx) = 0

Mark the pixel(row,col) as classified in the category label_idx, which may be in the range 0 to MAX_NUM_LABELS-1 Note that 0 is a valid label index, it does not mean “no label”.
