Defines the settings to use for Local tone mapping statistics for ISP version 5.
Local tone mapping parameters depend on statistics gathered from previous frames by the LTM sub block. It provides a global tone histogram with 128 bins and local average statistics for configurable 8x8 windows. Both of these support rectangular and elliptical masks to block certain image areas from statistics gathering.

| NvMediaBool NvMediaISPStatsLTMSettingsV5::enable |
Enable local tonemapping stats.
Definition at line 1063 of file nvmedia_isp.h.
| uint16_t NvMediaISPStatsLTMSettingsV5::localAvgWndHeight |
Height of local average statistics window in pixels.
Value must be even. See LocalAvgWidth documentation for recommendations on selecting value

| uint16_t NvMediaISPStatsLTMSettingsV5::localAvgWndWidth |
Width of local average statistics window in pixels.
Value must be even. Value should be selected so that the 8x8 grid of windows covers whole active image area, i.e. that 8 x StatsLocalAvgWndWidth >= image width. Also, the window should be roughly rectangular.
