Original Post here: https://iitmcvg.github.io/conferences/pysangamam-content/

Thank you for the wonderful participation yesterday at PySangamam 2018.

For those who missed the workshop, the following is the outline of topics we covered:

What is computer vision?

  • Computer Vision through the ages
  • Image and video representations in computers (pixels, colour spaces).
  • Why is computer vision hard?
  • Examples of different computer vision problems (detection, segmentation, shape from X, etc).

Computer Vision through the ages

  • Gradient Based Methods (HOG, HAAR).
  • Scale invariant Feature Matching Algorithms (SIFT and SURF).
  • Other tasks with classical Computer vision.
  • Issues with classical computer vision.

Rise of learning methods

  • Youtube cats, training on CPUs.
  • SAIL — the era of GPUs.
  • In a nutshell, ML+ NN = DL.
  • Alexnet and the impact of Imagenet.

The Deep Learning Era in flow

  • Introduction to Machine Learning, benefits of end-to-end solutions.
  • Using ML algorithms for Computer vision tasks (Hello world (MNIST with keras)).
  • Feed forward neural networks for MNIST classification.
  • Introduction to Convolutional Neural Networks (CNNs).
  • Using CNNs for Image Recognition .

Concept of Transfer Learning

  • Why transfer learn; Less data? Not always a problem.
  • Concept of Bottlenecks.
  • A hands on example.
  • Practitioner advice; Closing comments
