libXCam
Copyright (C) 2014-2018 Intel Corporation
libxcam core source code under the terms of Apache License, Version 2.0
Description:
libXCam is a project for extended camera features and focus on image quality improvement and video analysis. There are lots features supported in image pre-processing, image post-processing and smart analysis. This library makes GPU/CPU/ISP working together to improve image quality. OpenCL is used to improve performance in different platforms.
Features:
- Image processing features.
- Advanced features.
- Automotive surround view(360) stitching (OpenCL/CPU/GLES).
- Support bowl view 3D model stitching by 4 video input.
- Enable geometry remap for WFoV camera calibration(intrinsic and extrinsic data).
- Quality and performance improved (OpenCL/CPU/GLES).
- CPU version upstreamed into AOSP for automotive surround view.
- Enable Vulkan to improve performance.
- 360 video stitching (Equirectangular mode via OpenCL).
- Support 2-fisheye (>180 degree) video stream stitching.
- Performance and quality improved.
- Digital Video Stabilization:
- OpenCV feature-matched based video stabilization.
- gyroscope 3-DoF (orientation) based video stabilization.
- Blender: multi-band blender (OpenCL/CPU/GLES).
- Noise reduction (OpenCL).
- adaptive NR based on wavelet-haar and Bayersian shrinkage.
- 3D-NR with inter-block and intra-block reference.
- wavelet-hat NR (obsolete).
- Wide dynamic range (WDR) (OpenCL).
- histogram adjustment tone-mapping.
- gaussian-based tone-mapping (obsolete).
- Fog removal: retinex and dark channel prior algorithm (OpenCL).
- dark channel prior algorithm based defog.
- multi-scale retinex based defog (obsolete).
- Basic pipeline from bayer to YUV/RGB format (OpenCL / AtomISP).
- Gamma correction, MACC, color space, demosaicing, simple bilateral noise reduction, edge enhancement and temporal noise reduction.
- 3A features.
- Auto whitebalance, auto exposure, auto focus, black level correction, color correction, 3a-statistics calculation.
- Support 3rd party 3A lib which can be loaded dynamically.
- Support 3a analysis tuning framework for different features.
- Support smart analysis framework.
- Face detection interface/plugin.
- Enable gstreamer plugin.
- xcamsrc, capture from usb/isp camera, process 3a/basic/advanced features.
- xcamfilter, improve image quality by advanced features and smart analysis.
Prerequisite:
- install gcc/g++, automake, autoconf, libtool, gawk, pkg-config
- Linux kernel > 3.10
- install ocl-icd-dev, ocl-icd-opencl-dev
- If --enable-libcl, need compile ocl driver https://www.freedesktop.org/wiki/Software/Beignet/
- If --enable-opencv, suggest opencv versions [3.0.0 - 3.4.3]http://opencv.org (or: https://github.com/opencv/opencv/wiki)
- If --enable-gst, need install libgstreamer1.0-dev, libgstreamer-plugins-base1.0-dev
- If --enable-aiq, need get ia_imaging lib which we don't support.
- If --enable-render, need compile OpenSceneGraph library with configure option “-DOSG_WINDOWING_SYSTEM=X11” https://github.com/openscenegraph/OpenSceneGraph.git
- If --enable-gles, need to install mesa-3d library
- If --enable-vulkan, need to install mesa-3d library

Environment variable settings
For different --prefix options, the environment variables may be different. Please set the environment variable according to the actual situation.
--prefix=/usr/local:
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-1.0:$GST_PLUGIN_PATH
--prefix=/usr:
export LD_LIBRARY_PATH=/usr/lib/:$LD_LIBRARY_PATH
export GST_PLUGIN_PATH=/usr/lib/gstreamer-1.0:$GST_PLUGIN_PATH
$ ./autogen.sh [options]
--prefix=PREFIX install architecture-independent files in PREFIX [default=/usr/local]
--enable-debug enable debug, [default=no]
--enable-profiling enable profiling, [default=no]
--enable-drm enable drm buffer, [default=no]
--enable-aiq enable Aiq 3A algorithm build, [default=no]
