Sensory profiling is a very important tool in food industry, crucial in order to adapt the products to consumers’ preferences. Quantitative Descriptive Analysis (QDA) is a precise tool to relate characteristics of the product with consumers’ perception, since trained panels provide very detailed, robust, consistent, and reproducible results . However, creating and maintaining a well-trained […]

Triangulations and face morphing

Triangulations and face morphing

Mathematics

By David Orden

Face morphing has become quite popular in the last years; from mixing the faces of two celebrities to guessing how your baby could look, many TV shows and apps use software which changes one face into another through a continuous and smooth transition. Among the different mathematical tools that can be used for face morphing […]

Security in residential and public areas is a matter of great importance for many people. This is why some Internet providers are offering surveillance systems as a value-added service. Such surveillance systems have recently shifted from CCTVs to IP-based cameras, as the latter offer clear advantages to their users, like a more competitive cost and […]

This post is dedicated to the memory of Professor Ferran Hurtado, inspirational friend and colleague. Triangulations are extremely useful in computer graphics, with terrain modeling being an outstanding example: A mesh of points in 2D is triangulated and then the triangulation is lifted to obtain an -monotone polyhedral surface in 3D, called a 2.5D terrain […]
