Vision/Core

This is a small collection C++11 classes useful for various computer vision / robotics / GPGPU problems, largely inspired by the Kangaroo library. Nothing tested properly, most under development, unstable.

Features

Buffers

• Buffer1D - linear vector of elements, either Host/CUDA or OpenCL allocators.
• Buffer2D - 2D buffer of elements, either Host/CUDA or OpenCL allocators.
• Buffer3D - 3D buffer of elements, either Host/CUDA or OpenCL allocators.
• BufferPyramid - 2D buffer pyramid, either Host/CUDA or OpenCL allocators.
• CUDATexture - wrapper to see 2D buffer or OpenGL to get CUDA texture access.
• GPUVariable - single element buffer pretty much.
• Image2D - derived from Buffer2D, but adds interpolations and derivatives.
• ImagePyramid - Image2D pyramid.
• ReductionSum2D - 2D reductions CUDA + thrust, up to 4 variables and reductions over pyramids.
• Volume - derived from Buffer3D, but adds interpolations and derivatives.

Control

• PID - simple PID controller.
• VelocityProfile - Trapezoidal/Constant velocity profile generators.

Image

• ImagePatch - convenient access to a patch in a Buffer2D.
• PixelConvert - pixel type conversions.

Math

• Angles - angular quantities utilities + circular mean.
• DenavitHartenberg - robotic joint generator.
• Divergence - divergence operators.
• Fitting - fitting plane to points, circle or transformation.
• HammingDistance - portable Hamming distance (CPU/CUDA).
