SpatialLocationCalculator

Hi all ,

I am using the SpatialLocationCalculator as shown in the tutorial. I modified the size of the Roi to make it bigger. The resulting image shows different levels of depth values. How is the coordinate of z axis calculated in this case ? does it compute an average of the entire area or it takes the minimal/maximal depth value ?
can you help me understand how the z coordinate (depth) of the ROI is calculated in this case ?
Thank you in advance

I found the SpatialLocationCalculatorAlgorithm parameter. what are the options for this config and how each option computes the spatial coordinates ?

martin181818 does it compute an average of the entire area or it takes the minimal/maximal depth value ?

Via calculation algorithm which performs averaging on the ROI pixel depth values.

    /**
     * Calculation method used to obtain spatial locations
     * Average/mean: the average of ROI is used for calculation.
     * Min: the minimum value inside ROI is used for calculation.
     * Max: the maximum value inside ROI is used for calculation.
     * Mode: the most frequent value inside ROI is used for calculation.
     * Median: the median value inside ROI is used for calculation.
     * Default: median.
     */
SpatialLocationCalculatorAlgorithm calculationAlgorithm = SpatialLocationCalculatorAlgorithm::MEDIAN;

Thanks,
