Numerical Algorithms: Methods for Computer Vision, Machine Learning, and Graphics presents a new approach to numerical analysis for modern computer scientists. Using examples from a broad base of computational tasks, including data processing, computational photography, and animation, the textbook introduces numerical modeling and algorithmic design from a practical standpoint and provides insight into the theoretical tools needed to support these skills.

- Figure 1.6 We can visualize a function f(x1, x2) as a three-dimensional graph; then is the direction on the (x1, x2) plane corresponding to the steepest ascent of f. Alternatively, we can think of f(x1, x2) as the brightness at (x1, x2) (dark indicates a low value of f), in which case ▿f points perpendicular to level sets in the direction where f is increasing and the image gets lighter.

- Figure 4.2 Drawbacks of fitting function values exactly: (a) noisy data might be better represented by a simple function rather than a complex curve that touches every data point and (b) the basis functions might not be tuned to the function being sampled. In (b), we fit a polynomial of degree eight to nine samples from f(x) = |x| but would have been more successful using a basis of line segments.

As an example, keypoints marked in white on the two images in (b) are used to create (c) the aligned image.
- Figure 4.4 Suppose rather than taking (a) the sharp image, we accidentally take (b) a blurry photo; then, deconvolution can be used to recover (c) a sharp approximation of the original image. The difference between (a) and (c) is shown in (d); only high-frequency detail is different between the two images.
