Foundations
Week 1 · Intro to Linear Algebra for Visual Computing—I
Vectors, Dot Products & Matrices
Begin with the objects that carry visual information: vectors encode coordinates, directions, colors, and features, while matrices organize and transform them.
Syllabus focus
- Vectors and linear combinations
- Length and dot products
- Matrices
Core idea
A linear combination builds a new vector from existing directions. The dot product measures alignment and produces projections. A matrix is best understood through the transformation it applies.
v = αa + βbaᵀb = ‖a‖‖b‖ cos θy = Ax
Visual computing connection. These ideas appear immediately in coordinate changes, feature similarity, surface normals, color transforms, and geometric modeling.
