Linear And Nonlinear Least-Squares With Math.NET

This article explains how to solve linear and nonlinear least-squares problems and provides C# implementation for it. All the numerical methods used in the demo project stand on top of vector and matrix operations provided by the Math.NET numerical library.

Automatic Cropping Of Non Rectangular Images

Digital images are usually rectangles, but such rectangular boxes may contain "actual" image with arbitrary boundary. This article discusses a generic algorithm for finding largest rectangle that can still fit within the boundaries. Examples of such non-rectangular images are digital panoramas, projected images, scans and old photographs.
