2024-07-05libtuning: Copy files from raspberrypiStefan Klug
Copy ctt_{awb,ccm,colors,ransac} from the raspberrypi tuning scripts as basis for the libcamera implementation. color.py was renamed to ctt_colors.py to better express the origin. The files were taken from commit 66479605baca ("utils: raspberrypi: ctt: Improve the Macbeth Chart search reliability").

Opencv fails to load the image. The added license destroys the magic number. Fix, by moving the licence below the magic number.

2024-07-05libtuning: Backport improvements in MacBeth search reliabilityStefan Klug
Port commit 66479605baca ("utils: raspberrypi: ctt: Improve the Macbeth Chart search reliability") into libtuning. Previously the code would brighten up images in case the Macbeth Chart is slightly dark, and also zoom in on sections of it to look for charts occupying less of the field of view. But it would not do both together. This change makes the search for smaller charts also repeat that search for the brightened up images that it made earlier, thereby increasing the chances of success for non-optimal tuning images.

2024-06-14utils: libtuning: modules: Add skeletal AGC modulePaul Elder
Add a skeletal AGC module just so that we can have some AGC tuning values that we can use to test during development of AGC in the IPAs. As rkisp1 is the main target, we only add support for rkisp1 for now. The parameters are mostly copied from the hardcoded values in ctt, except for the metering modes.

2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>

2022-11-25utils: libtuning: parsers: Add yaml parserPaul Elder
Add a parser to libtuning for parsing configuration files in yaml format. At the moment it doesn't parse anything and simply returns an empty config. This is fine for the time being, as the only user of it is the rkisp1 tuning script, which only has an LSC module which doesn't consume anything from the configuration file. When a module comes around that requires the yaml parser, it can be implemented then.

Add a base LSC module to libtuning's collection of modules. It is based on raspberrypi's ctt's ALSC, but customizable for different lens shading table sizes, among other things. It alone is insufficient as a module, but it provides utilities that are useful for and which will simplify implementing LSC modules.
