Can AI Solve the Low
Light and HDR
Challenge?
Oren Debbi
CEO
Visionary.ai
Visionary.ai
• Enhancing video quality in
real-time using AI
• The world’s first fully software-
based ISP
• Based in Israel, our leadership
team holds over 50 patents in
the fields of AI and computer
vision.
Who Are We?
2
Our specialization
• Licensable IP, software and
integration services for real
time image quality
improvement
© All rights reserved. Visionary.ai 2023
to make cutting-edge
image quality available to
all cameras
Our Vision
True Night Vision

• Multiple sources of noise in image
sensors
• Low light makes noise worse
• Few photons per pixel = low signal to
noise
• Heat makes noise worse
• Hot silicon generates more random
noise
• Noise reduces capability of machine
vision
Noise - The Enemy of the Image

Noise - The Key to Unlocking Degrees of
Freedom for Designers
6
If you can remove image noise, you can
improve design parameters like:
• Low light performance
• Smaller and/or lower cost sensors
• Higher frame rate
• Shorter exposures (reduced motion blur)
• Reduce or eliminate cost of illumination

Smartphone Image Quality has Created a New
Standard of Consumer Expectations

Non-real-time noise performance vs time to
execute, at 0.2 Lux, 6000 Kelvin.
Denoising
performance close to
current leading
denoising approach,
“Restormer,” in less
than 0.005% of the
time
© All rights reserved. Visionary.ai 2023
• Classic denoising approaches can
cause loss of image sharpness
• This harms machine vision
performance
• Visionary.ai retains image quality,
measured by modular transfer
function MTF30 and MTF50 (higher
is better)
• Critically, our denoiser runs in real-
time
Denoising without Compromising Image

“Can AI Solve the Low Light and HDR Challenge?,” a Presentation from Visionary.ai

  • 1. Can AI Solve the Low Light and HDR Challenge? Oren Debbi CEO Visionary.ai
  • 2. Visionary.ai • Enhancing video quality in real-time using AI • The world’s first fully software- based ISP • Based in Israel, our leadership team holds over 50 patents in the fields of AI and computer vision. Who Are We? 2 Our specialization • Licensable IP, software and integration services for real time image quality improvement © All rights reserved. Visionary.ai 2023
  • 3. to make cutting-edge image quality available to all cameras Our Vision
  • 4. True Night Vision © All rights reserved. Visionary.ai 2023 4
  • 5. • Multiple sources of noise in image sensors • Low light makes noise worse • Few photons per pixel = low signal to noise • Heat makes noise worse • Hot silicon generates more random noise • Noise reduces capability of machine vision Noise - The Enemy of the Image 5 Noisy night image of a vehicle license plate © All rights reserved. Visionary.ai 2023
  • 6. Noise - The Key to Unlocking Degrees of Freedom for Designers 6 If you can remove image noise, you can improve design parameters like: • Low light performance • Smaller and/or lower cost sensors • Higher frame rate • Shorter exposures (reduced motion blur) • Reduce or eliminate cost of illumination © All rights reserved.

  • 13. Benchmarks vs Leading Denoising Algorithms 13 Visionary.ai BM3D Guided Filtering Restormer Non-real-time noise performance vs time to execute, at 0.2 Lux, 6000 Kelvin. Denoising performance close to current leading denoising approach, “Restormer,” in less than 0.005% of the time © All rights reserved. Visionary.ai 2023
  • 14. • Classic denoising approaches can cause loss of image sharpness • This harms machine vision performance • Visionary.ai retains image quality, measured by modular transfer function MTF30 and MTF50 (higher is better) • Critically, our denoiser runs in real- time Denoising without Compromising Image Sharpness 14 © All rights reserved.
