Study Notes

Epipolar Geometry

  • Fx in Epipolar Geometry: Represents a mapping between points in stereo images, relating corresponding points in two views.
  • Fundamental Matrix Estimation: Requires a minimum of eight point correspondences to solve for its parameters.
  • True Statement: The fundamental matrix encodes the intrinsic projective geometry between two views of a scene.

Fundamental Matrix Representation

  • Equation x' ⊤ F x = 0: Represents the epipolar constraint, indicating that the points x and x' are corresponding points in two images related by the fundamental matrix F.

Text Processing in Computing

  • Definition of Text Processing: Refers to the manipulation, formatting, and analysis of text data using computer algorithms.
  • 'Text' in Text Processing: Usually refers to any sequence of characters, including natural language and structured data formats.
  • 'Processing' in Text Processing: Indicates the operations performed on text, such as editing, transforming, or analyzing.

Functions of a Text Processor

  • Text Processor Capabilities: Can perform various tasks such as searching, replacing, formatting, and extracting data using specific computer commands.

Regular Expressions and Text Processing

  • Text Processing with Regular Expressions: Involves applying patterns to search, match, and manipulate text strings efficiently within larger bodies of text.
