about

nx_pose_preprocess.nx -- ViTPose top-down preprocessing: real image + GT bbox -> vitpose_input.bin. Pipeline (faithful to mmpose TopDownGetBboxCenterScale + TopDownAffine): decode baseline/progressive JPEG (nx_jpeg_decode_rgb) -> packed RGB -> aspect-fix bbox to 192:256 (3:4), pad x1.25 (mmpose default) -> crop box [x0,y0,cw,ch] -> bilinear resize crop -> 192x256 -> ImageNet normalize ((v/255-mean)/std, RGB) -> write CHW f32 LE (3*256*192*4 B) exactly as nx_vitpose_forward reads it. Emits data/mp_crop.txt "x0 y0 cw ch" so postprocess maps heatmap(48x64)->image coords with the SAME box. Config: data/mp_img_dest.txt (jpg path), data/mp_bbox.txt ("x y w h"). 100% sovereign decode+math. verdict: NOT_YET_EVALUATED lineage_id: nx_pose_preprocess_v1
