OpenCV

Basics

• Scalar
• Point
• Matrix
• Matrix type

• MatrixProperties
• PseudoInverse
• MatrixMultiplication
• IplImage image type

Input/Output (IO)

• Read an image
• Write an image
• Display an image

Calibration

• Calibrate the intrinsic parameters of a camera from a single image of a checkerboard

Convenience Functions

• Compose a projection matrix (P) from K, R, and T
• Convert the elements of a matrix from one type to another

Common Tasks
