Stop-Motion Photography Techniques

Freehand HDR photography with motion compensation

In theory HDR photography generated from exposure sequences is limited to pictures of still scenes preferably taken with the camera mounted on a tripod. Current state-of-the-art HDR imaging software relaxes this limitation by aligning the pictures with affine transformations. However, two pictures cannot be aligned with a single affine transformation if objects in the scene move or the position...

Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis

Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

MUAN: A Stop Motion Animation System

MUAN is a Stop Motion Animation System for Education. The MUAN system allows animation movie production offering an integrated kit of hardware and software. It consists of a computer with Linux, a digital video camera and support over necessary acessories for interconnection. The software was developed under Linux by the team of VISGRAF Laboratory, in cooperation with ANIMA MUNDI and IBM Brazil...

RNA folding pathways in stop motion

We introduce a method for predicting RNA folding pathways, with an application to the most important RNA tetraloops. The method is based on the idea that ensembles of three-dimensional fragments extracted from high-resolution crystal structures are heterogeneous enough to describe metastable as well as intermediate states. These ensembles are first validated by performing a quantitative compari...
