However, there seems to\nnow be demand for it for bayesian awb, so this series has been brought\nout of bitrot.\n\nv3 only has minor formatting (both text and code) fixes.\n\nPaul Elder (2):\n ipa: libipa: Add Lux helper\n ipa: rkisp1: Add Lux algorithm module\n\n src/ipa/libipa/lux.cpp | 181 ++++++++++++++++++++++++++\n src/ipa/libipa/lux.h | 42 ++++++\n src/ipa/libipa/meson.build | 2 +\n src/ipa/rkisp1/algorithms/lux.cpp | 80 ++++++++++++\n src/ipa/rkisp1/algorithms/lux.h | 36 +++++\n src/ipa/rkisp1/algorithms/meson.build | 1 +\n src/ipa/rkisp1/ipa_context.h | 4 +\n 7 files changed, 346 insertions(+)\n create mode 100644 src/ipa/libipa/lux.cpp\n create mode 100644 src/ipa/libipa/lux.h\n create mode 100644 src/ipa/rkisp1/algorithms/lux.cpp\n create mode 100644 src/ipa/rkisp1/algorithms/lux.h" }
