Who is this presentation for?

  • Machine learning engineers




When you take any photograph using a digital camera, defects can be introduced depending on lighting, exposure, etc., which can include underexposure or overexposure, out-of-focus blur, etc. You can end up spending a lot of time on image-editing software fixing these defects.

Akhilesh Kumar investigates approaches that make it easy to identify the region of the defects. You’ll see a general adversarial network- (GAN) based solution that can automatically fix some defects, like over- or underexposure. Akhilesh details how a GAN-based solution can be better than the traditional approach of correcting images, and how this can be applied on defective images by treating videos frame by frame.

Prerequisite knowledge

  • A good understanding of machine learning and deep learning

What you'll learn

  • Find out how cutting-edge technology like GANs can be used for fixing image defects
  • Learn about GANs
  • Understand how deep learning-based methods can be better than traditional algorithms
