Motion interpolation is a programming technique in data-driven character animation that creates transitions between example motions and extrapolates new motions. Example motions are often created through keyframing or motion capture. However, keyframing is labor-intensive and lacks varieties of motion, and both processes result in motions that ...
The computed interpolation process is then used to insert many new values in between these key points to give a "smoother" result. In its simplest form, this is the drawing of two-dimensional curves. The key points, placed by the artist, are used by the computer algorithm to form a smooth curve either through, or near these points.
Examples of algorithms for this task include New Edge-Directed Interpolation (NEDI), [1] [2] Edge-Guided Image Interpolation (EGGI), [3] Iterative Curvature-Based Interpolation (ICBI), [citation needed] and Directional Cubic Convolution Interpolation (DCCI). [4] A study found that DCCI had the best scores in PSNR and SSIM on a series of test ...
Quarter-pixel motion compensation, much like half-pixel, is achieved through interpolation. Different specific schemes are used in different designs: VC-1 uses bicubic interpolation. H.264/AVC uses a 6-tap filter for half-pixel interpolation and then simple linear interpolation to achieve quarter-pixel precision from the half-pixel data.
Gouraud-shaded triangle mesh using the Phong reflection model. Gouraud shading (/ ɡ uː ˈ r oʊ / goo-ROH), named after Henri Gouraud, is an interpolation method used in computer graphics to produce continuous shading of surfaces represented by polygon meshes.
Rather than interpolate in time, as with animation curves, or over space, as with meshes, PSD views animation as interpolation over the domain of the character's pose. PSD was an early use of machine learning and neural networks in computer graphics: the radial basis interpolation that is often used to implement PSD is equivalent to a neural ...
Several key mistakes could throw off the accuracy of blood pressure readings for people who take them at home. The average "normal" blood pressure is 120/80, according to the American Heart ...
The high performance of Velocity's internal animation engine helped to repopularize JavaScript-based web animation, which had previously fallen out of favor for CSS-based animation due to its speed advantages over older JavaScript libraries that lacked a focus on animation. [19]
