Because of this, the\ncrosstalk is implemented using a generic matrix interpolator, which is\nadded to libipa, in addition to a Matrix class.\n\nv3 mainly adds ccm offsets, and some fixes some initialization and\nasserts.\n\nv4 cleans up / optimizes the Matrix class and supports the reorganized\ntuning file layout for color correction matrices.\n\nv5 mainly adds documentation, as well as a simple cache to the matrix\ninterpolator.\n\nv6 fixes documentation (again).\n\nv7 fixes offsets initialization and adds ccm to metadata, as well as\ncopyright and licenses, as these classes weren't actually copied.\n\nPaul Elder (3):\n ipa: libipa: Add Matrix class\n ipa: libipa: Add MatrixInterpolator class\n ipa: rkisp1: algorithms: Add crosstalk algorithm\n\n src/ipa/libipa/matrix.cpp | 123 ++++++++++++++++++\n src/ipa/libipa/matrix.h | 172 +++++++++++++++++++++++++\n src/ipa/libipa/matrix_interpolator.cpp | 110 ++++++++++++++++\n src/ipa/libipa/matrix_interpolator.h | 124 ++++++++++++++++++\n src/ipa/libipa/meson.build | 4 +\n src/ipa/rkisp1/algorithms/ccm.cpp | 140 ++++++++++++++++++++\n src/ipa/rkisp1/algorithms/ccm.h | 50 +++++++\n src/ipa/rkisp1/algorithms/meson.build | 1 +\n src/ipa/rkisp1/ipa_context.h | 5 +\n 9 files changed, 729 insertions(+)\n create mode 100644 src/ipa/libipa/matrix.cpp\n create mode 100644 src/ipa/libipa/matrix.h\n create mode 100644 src/ipa/libipa/matrix_interpolator.cpp\n create mode 100644 src/ipa/libipa/matrix_interpolator.h\n create mode 100644 src/ipa/rkisp1/algorithms/ccm.cpp\n create mode 100644 src/ipa/rkisp1/algorithms/ccm.h"}
