Field Documentation

disableLensShadingCorrection

NvSiplBool nvsipl::NvSiplISPHistogramStatsOverride::disableLensShadingCorrection

boolean flag to disable lens shading compensation for histogram statistics block

Definition at line 602 of file NvSIPLISPStat.hpp.

ellipticalMask

NvSiplISPEllipse nvsipl::NvSiplISPHistogramStatsOverride::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.

• Supported values for X coordinate of the center: [0, input width]
• Supported values for Y coordinate of the center: [0, input height]
• Supported values for horizontal axis: [16, 2 x input width]
• Supported values for vertical axis: [16, 2 x input height]
• Supported values for angle: [0.0, 360.0]

Definition at line 598 of file NvSIPLISPStat.hpp.

ellipticalMaskEnable

NvSiplBool nvsipl::NvSiplISPHistogramStatsOverride::ellipticalMaskEnable

Holds a Boolean to enable an elliptical mask for excluding pixels outside a specified area.

Definition at line 585 of file NvSIPLISPStat.hpp.

enable

NvSiplBool nvsipl::NvSiplISPHistogramStatsOverride::enable

Holds a Boolean to enable histogram statistics Control block.

Definition at line 547 of file NvSIPLISPStat.hpp.

knees

uint8_t nvsipl::NvSiplISPHistogramStatsOverride::knees[NVSIPL_ISP_HIST_KNEE_POINTS]

Holds bin index specifying different zones in the histogram.

Each zone can have a different number of bins.

• Supported values: [1, 255]

Definition at line 558 of file NvSIPLISPStat.hpp.

offset

float_t nvsipl::NvSiplISPHistogramStatsOverride::offset

Holds offset to be applied to input data prior to bin mapping.

• Supported values: [-2.0, 2.0]

Definition at line 552 of file NvSIPLISPStat.hpp.

ranges

uint8_t nvsipl::NvSiplISPHistogramStatsOverride::ranges[NVSIPL_ISP_HIST_KNEE_POINTS]

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.

• Supported values: [0, 21]

Definition at line 565 of file NvSIPLISPStat.hpp.

rectangularMask

NvSiplRect nvsipl::NvSiplISPHistogramStatsOverride::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. A rectangle ((right > left) && (bottom > top)), or must be ((0,0), (0,0)) to disable the rectangular mask.

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
