1. Geometric Transformations in Computer Vision Overview of key geometric transformations used in computer vision including translation, rotation, scaling, affine and perspective transformations.

2. Translation Translation shifts an image in the x or y direction. It is represented by adding a constant to the coordinates.

3. Rotation Rotation turns an image around a point. It is defined by an angle and a center of rotation.

4. Scaling Scaling changes the size of an image. It is achieved by multiplying the coordinates by a scaling factor.

5. Affine Transformation Affine transformation preserves points, straight lines, and planes. It includes translation, rotation, scaling, and shearing.

6. Perspective Transformation Perspective transformation simulates the effect of viewing an image from a different angle or depth. It uses a 3x3 matrix.

7. Applications Geometric transformations are used in image registration, object tracking, and camera calibration.
