I'm gonna write down the memo of study "Multiple View Geometry in computer vision".Having read the foreword of this book, this sentence was so interes

Before you read!This book has two notations,"Geometric Representation" and "Algebraic Representation". It would be confused of these combined notation

Conic can be represented by 6 parameters, $$ax^2 + bxy + cy^2 + dx + ey + f = 0$$it can also represented with matrix form like this:$\\begin{pmatrix}a

Definition : A mapping $h(.): P^2 => P^2$ such that $$x_1, x_2, x_3 \\ \\ \\ lie \\ on \\ the \\ same \\ line => h(x_1), h(x_2), h(x_3) $$Transformati

Here we're gonna learn how the point in the world coordinate is mapped to the point in the camera coordinate.Global steps1) World coordinate to camera

Given 2D to 2D point correspondences {$x_i <=> x'\_i$} Compute a 3x3 matrix $H$ such that$$ Hx_i = x'\_i \\ \\ for \\ all \\ i$$The Number of requi
