* 2 cameras 1080p stitching enabling (CPU/GLES)
* DNN inference support processing video stream
* Use Intel open source graphics compute runtime for OpenCL (NEO) - will not support Beignet driver- Remove obsolete allow-newer-opencv.patch- Add Fix-build-with-Vulkan-1.2.140.patch- Removed obsolete or irrelevant build dependencies- Enable build for all architectures, disable DRM for everything but Intel.
* Thu May 21 2020 Aaron Puchert - Update to version 1.2.2
* GLES compute framework enabling. - enable GL image processing framework. - enable features of multi-band blender, geometry remap and data-copy.
* GLES surround-view stitching enabling. - GLES stitching enabled (feature-match may support later). - performance optimized on compute shaders.
* Vulkan compute framework enabling. - enabled Vulkan image processing under xcam framework. - vk-copy-handler as sample code.
* suggest OpenCV version [3.0.0 - 3.4.3]
* support CPU stitching based on dual-const and dual-curve scaling factors.
* support OpenCL stitching based on auto-scale in vertical 2D-direction.
* change test-soft-image to test-surround-view
* Vulkan surround-view stitching enabling. - enable features of multi-band blender and geometry remap. - enable Vulkan image stitching. (feature-match may support later)
* Surrond-view texture rendering. - enable 3D surround view scene rendering and manipulation.
* require OpenSceneGraph minimal version 3.3.2
* DNN inference framwork enabling. - enable pedestrian and vehicle detection based on OpenVino
* OpenCV feature match enabled for image stitching pipeline (GLES/Vulkan/CPU) - support three versions of feature match: default, cluster, capi
* Abstract OpenCV source in ocv module, and build into a separate static library- Require pkgconfig(opencv), because this still needs OpenCV 3.- Add allow-newer-opencv.patch: Allow all 3.x.x versions.- Disable 3alib to prevent compiler errors due to missing linux/atomisp.h.- Enable Vulkan support.
* Tue Oct 02 2018 Antonio Larrosa - 1.1.0- Update to version 1.1.0
* CPU stitching enabled for automotive surround view in Linux/Android. - enable CPU multi-thread image processing framework. - enable multi-band blender, geometry remap, data-copy, OpenCV feature match. - enable 3D-bowl model stitching. - support generic Android platform. - CPU version of surround view stitching upstream to Android Open Source Project.
* surround-view OpenCL stitching feature enabled and quality improvement. - add dewarp process based on bowl view model in geometry map. - support multiple (4) cameras stitching. - add new selection method based on clustering in feature match to improve quality of stitching. - auto scale in x direction is done and y direction is WIP. - quality tune on different datasets, both indoor and outdoor.
* support standard OpenCL 2.0+ driver (VPG OCL driver) - support standard OpenCL buffer. - remove libdrm dependency. - drm preview removed from test-device-manager, test-pipe-manager and usb camera.
* enable deblurring feature based on OpenCV. (GSoC program) - based on deconvolution algorithm filters - support noise estimation - support edgetaper
* surround view solution will be integrated into Android EVS (exterior view system) WIP
* add sample recipe for yocto build (libxcam/doc/yocto).
* Thu Oct 12 2017 jengelhAATTinai.de- Update package summary.
* Mon Sep 04 2017 alarrosaAATTsuse.com- Update to version 1.0.0
* 360 video stitching performance and quality improvement. - enable geometry map to improve performance. - quality tuned on different resolutions (1080P and 4K). - support CPU and OpenCL path in feature match. - enable lens shading correction based on fisheye image.
* gyroscope-based video stabilization enabling. - enable gyroscope 3-DoF (orientation) assist video stabilization. - orientation (gyro) data should be measured by quaternion as the pose of target frame reference to base frame
* CL framework refine. - enable CL argument template instead of member variables in kernel. - CL kernel support async mode. - image handler take over input/output buffer management from image kernel.
* prepare libxcam debian package and fix most warnings.- Remove fix-build-errors.diff which is no longer required- Increased soname to 1- The pkgconfig file has been renamed from xcam to libxcam
* Thu May 11 2017 alarrosaAATTsuse.com- Use --disable-aiq when configuring libxcam. AIQ/ia_imaging is an Intel proprietary 3A library.
* Tue May 09 2017 alarrosaAATTsuse.com- Initial release of libxcam- Version 0.9.0- Add fix-build-errors.diff to build correctly
