Product wise computer vision development

  1. 1. Product-Wise Computer Vision Development
  2. 2. Agenda• Common CV Development Process• Pitfalls• Why this happens• Suggested Computer Vision Process• Future CV Development• About me
  3. 3. Common CV Development Initial Develop algorithm on Matlab Demo PC Demo Realtime Demo PC Product PC ProductPort Algorithm Port Algorithm Mobile to Platform1 to Platform2 Product
  4. 4. What’s wrong with it• Matlab code is written as Develop algorithm “demo”/PoC on Matlab• Fast, Dirty• written with low development resource• use proprietary algorithms
  5. 5. What’s wrong with it Port Algorithm• This step sometime includes: to Platform1 • understanding mobile requirements • Optimization to platform’s SIMD • Memory optimization • sometime full re-written of the algorithm since its too computationally intensive for mobile
  6. 6. Contributing factors tocommon CV Project Process• Matlab stage • As a university or a garage SU, developers have low development resources• PC Stage • NIH - Developers prefer their proprietary version over popular algorithms. • at this stage (PoC/Demo) developers doesnt think on mobile optimization
  7. 7. Contributing factors tocommon CV Project Process• Platform Stage • Optimization starts from high memory and CP resource demanding PC code • A considerable portion of the code doesn’t use standard OpenCV functions and requires hand made SIMD optimization • Sometimes companies discover that the algorithm is too resource demanding and re-writes the algorithm for the mobile platform
  8. 8. Product-wise Computer Vision Development Initial Develop initial PoC with OpenCV Demo PC Product PC RT Demo Product Platform fixed-point ported non-OpenCV agnostic Algorithms Minimize Memory requirements Optimized codeUse platform-X optimized OpenCV for Platform product (FastCV, TADP, CEVA-CV) Optimized
  9. 9. Product-wise Computer Vision development• Product wise CV development is guided by the vision of a multi-platform product. This leads to: • Relay on a common CV library->OpenCV • minimization of non-OpenCV functions (saves platform specific SIMD optimization) • Separate between PC Product and optimized C code used as base for porting to mobile / embedded platforms
  10. 10. Future Development with OpenVX• Khronos compliant SoC will conform to a unified “OpenCV-Like” API• Enables easy porting to all supporting platforms•
