the 2D point (x,y) by a 3D point (x,y,z) using the homogenous coordinates, the perspective projection can be represented as: [█(x`@y`@z`)] = [█(f 0 0 0@0 f 0 0@0 0 1 0)] [█(X@Y@Z@1)] ……………………………...... (2.55) Fig. 2.19 shows a 360-degree panorama picture of the center courtyard of the Sony Center at the Potsdamer Platz in Berlin which was generated from 126 individual photos using autostitch.

This step completes the segmentation removing static objects from the grayscale images $T_i$ using Eigen-Background decomposition. First, each image $T_i \in \mathbb{R}^{n_x\times n_y} $ is reshaped into a column vector $I_i \in \mathbb{R}^{n_p\times 1}$. These $n_t$ vectors become the $i-th$ column of a video matrix $A(n_p\, , \, n_t)$, after having removed the average image: \begin{equation} A_{(n_s \times n_t)}=\begin{pmatrix} \hat{I}_1 & \hat{I}_2 & \cdots & \hat{I}_{n_t}…

The type of scanner is a modality-dependent feature. For example, MRIs and CT scanners are differ in size and functions. In medical ultrasounds, patients are not required to enter a scanner to be tested for CAD. These intrinsic modality-dependent differences were therefore considered as important test-specific attributes. In a DCE on scanning modalities to diagnose focal liver lesions, the type of scanner used was studied and shown to influence patient preferences for diagnostic tests (Whitty et…

We don’t see much of the facial performance capture in movies as it requires a lot of effort. You have to record an actor making all kinds of facial expressions in different conditions frequently for training a capture system to match expressions, which is kind of difficult for a studio that doesn’t have much money. Disney Research has found a solution for this. It has developed a facial capture system that would dramatically reduce effort and time to capture facial expressions. With the facial…

and Computer Generated animation. Traditional animation is created by drawing every frame by hand. Then these frames are coloured and scanned onto a computer and the frames synced with sound. It’s an extremely time-consuming and labour intensive process. Stop motion is when an animator photographs an object or person one frame and motion at a time. Then those photographs are combined and sped up. Computer Generated animation is when an animator uses computer software to animate. The computer…

In this section, I will discuss how motion capture technology used in the making of ‘Avatar’ particularly via the swing camera. Motion capture in Avatar was exceptionally plugged for creating the realism of the film. However, motion capture was used in interestingly and creative ways in Avatar. One aspect of such use is employment of swing camera. People may ask what is swing camera? Swing camera is a virtual camera that could show the low resolution view of Pandora when shot the motion capture…

Virtual environment allows the user to interact with the computer simulation environment, where the user experience is the interaction between the real and the imagined. Augmented reality and virtual reality technology enhanced mixing two. Virtual enhanced by combining real objects and computer data, virtual items will be generated in reality. This means that the user can see coexist in the same space of virtual and real objects. But just let enhancement technology of virtual items appear in…

The use of 3D animation has grown enormously in feature films over the last decade. Major film studios, such as Disney and Pixar have released more 3D animated movies than ever before. Technology is advancing and consumers are demanding realistic animation along with this evolution. Based on the performance of recent 3D films, the trend of 3D animation is bound to continue and develop further. 3D animation’s influence on American society is growing with the help of the stable major…

local schools. I was doing everything I wanted to do learning things I was interested in. When I applied to colleges I Applied to SUNY schools that had Graphic Design Majors and ended up going to Alfred State College as a Digital media and animation major. I was told that we would explore the world of 2D and 3D animation along with areas of graphic design, photography and videography. After spending 5 semesters in the program gaining knowledge in other programs such as Brackets, Maya, Adobe…

Jingnan Zhang English 3: Block Ms. Bunosky February 15, 2017 Archetypes in Toy Story One doesn’t usually watch movies and critically think about what is happening in it, but when one analyzes thoroughly, the audience can find some impressive things in the plots of these films. In the movie, Toy Story 3, the audience can clearly see a set of archetypes through the characters. Woody would be considered the hero, Buzz can be seen as the innocent person, and Lotso can be seen as the ruler/dictator…
