Field Documentation
◆ ellipticalMask
| NvSiplISPEllipse nvsipl::NvSiplISPHistogramStats::ellipticalMask |
Holds an elliptical mask for excluding pixels outside a specified area.
Coordinates of the image top left and bottom right points are (0, 0) and (width, height), respectively.
Definition at line 488 of file NvSIPLISPStat.hpp.
◆ ellipticalMaskEnable
| NvSiplBool nvsipl::NvSiplISPHistogramStats::ellipticalMaskEnable |
Holds a Boolean to enable an elliptical mask for excluding pixels outside a specified area.
Definition at line 481 of file NvSIPLISPStat.hpp.
◆ ellipticalWeightEnable
| NvSiplBool nvsipl::NvSiplISPHistogramStats::ellipticalWeightEnable |
Holds a Boolean to enable elliptical weighting of pixels based on spatial location.
This can be used to compensate for lens shading when the histogram is measured before lens shading correction.
Definition at line 494 of file NvSIPLISPStat.hpp.
◆ enable
| NvSiplBool nvsipl::NvSiplISPHistogramStats::enable |
Holds a Boolean to enable histogram statistics block.
Definition at line 443 of file NvSIPLISPStat.hpp.
◆ knees
| std::array<uint8_t, NVSIPL_ISP_HIST_KNEE_POINTS> nvsipl::NvSiplISPHistogramStats::knees |
Holds bin index specifying different zones in the histogram.
Each zone can have a different number of bins. Valid Range: [1, 255]
Definition at line 454 of file NvSIPLISPStat.hpp.
◆ offset
| float_t nvsipl::NvSiplISPHistogramStats::offset |
Holds offset to be applied to input data prior to bin mapping.
Valid Range: [-2.0, 2.0]
Definition at line 448 of file NvSIPLISPStat.hpp.
◆ radialTF
| NvSiplISPRadialTF nvsipl::NvSiplISPHistogramStats::radialTF |
Holds a radial transfer function for elliptical weight.
Valid Range: Check the declaration of NvSiplISPRadialTF.
Definition at line 499 of file NvSIPLISPStat.hpp.
◆ ranges
| std::array<uint8_t, NVSIPL_ISP_HIST_KNEE_POINTS> nvsipl::NvSiplISPHistogramStats::ranges |
Holds \(log_2\) range of the pixel values to be considered for each zone.
The whole pixel range is divided into NVSIPL_ISP_HIST_KNEE_POINTS zones. Valid Range: [0, 21]
Definition at line 461 of file NvSIPLISPStat.hpp.
◆ rectangularMask
| NvSiplRect nvsipl::NvSiplISPHistogramStats::rectangularMask |
Holds a rectangular mask for excluding pixels outside a specified area.
The coordinates of image top left and bottom right points are (0, 0) and (width, height), respectively. Set the rectangle mask to include the full image (or cropped image for the case input cropping is enabled) if no pixels need to be excluded.
The rectangle settings(x0, y0, x1, y1) must follow the constraints listed below:
- (x0 >= 0) and (y0 >= 0)
- x0 and x1 should be even
- (x1 <= image width) and (y1 <= image height)
- rectangle width(x1 - x0) >= 2 and height(y1 - y0) >= 2
