Facial Motion Capture
Facial motion capture is the process of electronically converting the movements of a person's face into a digital database using cameras or laser scanners. This database may then be used to produce computer graphics (CG), computer animation for movies, games, or real-time avatars. Because the motion of CG characters is derived from the movements of real people, it results in a more realistic and nuanced computer character animation than if the animation were created manually. A facial motion capture database describes the coordinates or relative positions of reference points on the actor's face. The capture may be in two dimensions, in which case the capture process is sometimes called "expression tracking", or in three dimensions. Two-dimensional capture can be achieved using a single camera and capture software. This produces less sophisticated tracking, and is unable to fully capture three-dimensional motions such as head rotation. Three-dimensional capture is accomplished using ...

3D Scanning
3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects. For example, industrial computed tomography scanning, structured-light 3D scanners, LiDAR and Time Of Flight 3D Scanners can be used to construct digital 3D models, without destructive testing. Collected 3D data is useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality. Other common applications of this technology include augmented reality, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Camera
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras (which are still available). High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can ...

Avatar (2009 Film)
''Avatar'' (also marketed as ''James Cameron's Avatar'') is a 2009 epic science fiction film directed, written, co-produced and co-edited by James Cameron, and starring Sam Worthington, Zoe Saldana, Stephen Lang, Michelle Rodriguez, and Sigourney Weaver. It is set in the mid-22nd century when humans are colonizing Pandora, a lush habitable moon of a gas giant in the Alpha Centauri star system, in order to mine the valuable mineral unobtanium. The expansion of the mining colony threatens the continued existence of a local tribe of Na'vi – a humanoid species indigenous to Pandora. The title of the film refers to a genetically engineered Na'vi body operated from the brain of a remotely located human that is used to interact with the natives of Pandora. Development of ''Avatar'' began in 1994, when James Cameron wrote an 80-page treatment for the film. Filming was supposed to take place after the completion of Cameron's 1997 film ''Titanic'', for a planned release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mova (camera System)
Mova Contour is a multi-camera high resolution facial motion capture, facial capture system originally developed by former Apple Computer engineer Steve Perlman (entrepreneur), Steve Perlman. It records surfaces (specifically of actors' faces) digitally, by using fluorescent makeup and Triangulation (computer vision), stereo triangulation, allowing for very detailed digitization and manipulation. The system captures images which are then used to generate dense per frame surface reconstructions. It then generates a temporally coherent mesh by tracking an invisible random pattern of fluorescent makeup that is applied to the capture surface. Mova technology was first used in ''The Curious Case of Benjamin Button (film), The Curious Case of Benjamin Button'' for building a realistic 3D face model of Brad Pitt. The first film credit that Mova technology received was for its use in The Incredible Hulk (film), The Incredible Hulk to capture Edward Norton's expressions and Superimposition, s ...

The Curious Case Of Benjamin Button (film)
''The Curious Case of Benjamin Button'' is a 2008 American fantasy romantic drama film directed by David Fincher. The storyline by Eric Roth and Robin Swicord is loosely based on the 1922 short story of the same name by F. Scott Fitzgerald. The film stars Brad Pitt as a man who ages in reverse and Cate Blanchett as the love interest throughout his life. The film also stars Taraji P. Henson, Mahershala Ali, Julia Ormond, Jason Flemyng, Elias Koteas, and Tilda Swinton. Producer Ray Stark bought the film rights to do the short story in the mid-1980s with Universal Pictures backing the film, but struggled to get the project off the ground until he sold the rights to producers Kathleen Kennedy and Frank Marshall in the 1990s. Although it was moved to Paramount Pictures in the 1990s, the film did not enter production until after Fincher and Pitt signed on along with the rest of the cast in 2005. Principal photography began in November 2006 and wrapped up in September 2007. Digital D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Facial Recognition System
A facial recognition system is a technology capable of matching a human face from a digital image or a video frame against a database of faces. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image. Development began on similar systems in the 1960s, beginning as a form of computer application. Since their inception, facial recognition systems have seen wider uses in recent times on smartphones and in other forms of technology, such as robotics. Because computerized facial recognition involves the measurement of a human's physiological characteristics, facial recognition systems are categorized as biometrics. Although the accuracy of facial recognition systems as a biometric technology is lower than iris recognition and fingerprint recognition, it is widely adopted due to its contactless process. Facial recognition systems have been deployed in advanced human–compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CMOS Camera
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOSFET, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS logic, NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as Camera phone, cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the ...

Film Frame
In filmmaking, video production, animation, and related fields, a frame is one of the many ''still images'' which compose the complete ''moving picture''. The term is derived from the historical development of film stock, in which the sequentially recorded single images look like a framed picture when examined individually. The term may also be used more generally as a noun or verb to refer to the edges of the image as seen in a camera viewfinder or projected on a screen. Thus, the camera operator can be said to keep a car in frame by panning with it as it speeds past. Overview When the moving picture is displayed, each frame is flashed on a screen for a short time (nowadays, usually 1/24, 1/25 or 1/30 of a second) and then immediately replaced by the next one. Persistence of vision blends the frames together, producing the illusion of a moving image. The frame is also sometimes used as a unit of time, so that a momentary event might be said to last six frames, the actual dur ...

Eigenface
An eigenface () is the name given to a set of eigenvectors when used in the computer vision problem of human face recognition. The approach of using eigenfaces for recognition was developed by Sirovich and Kirby and used by Matthew Turk and Alex Pentland in face classification. The eigenvectors are derived from the covariance matrix of the probability distribution over the high-dimensional vector space of face images. The eigenfaces themselves form a basis set of all images used to construct the covariance matrix. This produces dimension reduction by allowing the smaller set of basis images to represent the original training images. Classification can be achieved by comparing how faces are represented by the basis set. History The eigenface approach began with a search for a low-dimensional representation of face images. Sirovich and Kirby showed that principal component analysis could be used on a collection of face images to form a set of basis features. These basis images, k ...
