anr模块

enable_grey_treatment_thr_modification

控制开启边缘去彩噪

detect_grey_condition_chromaticity_thr_low

detect_grey_condition_chromaticity_thr_high

detect_grey_condition_y_max_derivative_thr_low

detect_grey_condition_y_max_derivative_thr_high

检测是否需要去彩噪的threshold

thr_modification_target_y

thr_modification_target_u

thr_modification_target_v

检测到需要加强edge false color denois才生效, 值越打越强

luma_filter_lut_thr_y

luma_filter_lut_thr_uv

为了解决lsc导致的噪声，按照半径区分, 值越大去噪越强

chroma_filter_lut_thr_y

chroma_filter_lut_thr_uv

为了解决lsc导致的噪声，按照半径区分, 值越大去噪越强

y_threshold_per_y

u_threshold_per_y

v_threshold_per_y

值越大去噪越强, 最常用

luma_input_indication_thr_modification_scale

chroma_input_indication_thr_modification_scale

full path上不认为是噪声, 但是DC4上需要做去噪, 此时开启inter length, 如果inter length的值为32, 则full path 的threshold就是full path threshold的2倍

dcblend2_luma_strength_function

dcblend2_chroma_strength_function（0 0 0 0 64 128）融合权重最大值, 去噪最强

一般不动
