Prerequisite Knowledge

Attendees should have a technical background, although no specific skills are required.

Description

To set the stage, we’ll cover:

  • What card.io does (very briefly)
  • What the main challenges were in building card.io

We’ll then step through the card.io processing pipeline:

  • Frame selection
  • Edge, line, and card detection
  • Vertical and horizontal segmentation
  • Number categorization
  • Aggregation

Throughout, we will discuss key user experience, product, and technical insights that went into card.io.

Attendees will come away with an understanding of the practicalities of building a real world computer vision product.
