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.
      • 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.
    • hybrid 3a plugin.
  • 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:

Building and installing:

  • 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:
