TSBB21 Computational Photography

The course TSBB21 is given in the second period of the autumn semester, HT2. It gives 6 ECTS credit points.
This course was previously called TSBB09 Image Sensors (2021 and earlier).
This page is valid for autumn semester 2024-HT2. Note that some updates will be made, though.

Course content overview

The course describes the function of modern digital cameras (for still and video images).
We analyze the process that from a luminous flux into the camera forms pixel values that
can be combined and corrected through integrated calculations and finally read out in the
form of an image. The collective name for this process is computational photography, and
this includes optics, geometry, electronics and the calculations that improve the end result.
Special types of cameras such as infrared cameras and distance cameras are also covered in
the course. Main topics of the course are:

• The digital camera: sensor structure, bayer patterns, noise sources, lens effects, etc.

• 3D visualization: simulation of the light source interaction with surfaces and volumes
• Camera geometry: the pinhole camera, projective geometry, homogeneous coordinates, homography

• Camera calibration and an application: panorama stitching
  
• Infrared and multispectral cameras

• Range cameras and point clouds

• Specialized cameras, e.g. high dynamic range (HDR), coded aperture
