Summary and next steps

A summary of the material covered in week 5 of Introduction to image analysis for plant phenotyping
This week we expanded our discussion of image analysis to consider data types beyond 2D images.

This includes:

  • Video data, how it differs from still images and common video data types
  • Pixel-based methods for motion detection in video
  • Use of background subtraction and median filtering in motion detection
  • Extraction of image data from video using OpenCV
  • Optic flow: measuring direction and magnitude of movement
  • Using models of shape for object tracking such as active contour models
  • 3D volumetric image data and how to view and manipulate it
  • Aerial imaging: mosaicing and image registration
  • Hyperspectral and multispectral images, and vegetation indices such as NDVI

A notable data type not covered this week is 3D model representations of plants, such as meshes and point clouds, which we will look at next week, the final week of course.
