Motion Enriching Using Humanoide Captured Motions
MASTER THESIS: MOTION ENRICHING USING HUMANOIDE CAPTURED MOTIONS STUDENT: SINAN MUTLU ADVISOR : A NTONIO SUSÌN SÀNCHEZ SEPTEMBER, 8TH 2010 COURSE: MASTER IN COMPUTING LSI DEPERTMANT POLYTECNIC UNIVERSITY OF CATALUNYA 1 Abstract Animated humanoid characters are a delight to watch. Nowadays they are extensively used in simulators. In military applications animated characters are used for training soldiers, in medical they are used for studying to detect the problems in the joints of a patient, moreover they can be used for instructing people for an event(such as weather forecasts or giving a lecture in virtual environment). In addition to these environments computer games and 3D animation movies are taking the benefit of animated characters to be more realistic. For all of these mediums motion capture data has a great impact because of its speed and robustness and the ability to capture various motions. Motion capture method can be reused to blend various motion styles. Furthermore we can generate more motions from a single motion data by processing each joint data individually if a motion is cyclic. If the motion is cyclic it is highly probable that each joint is defined by combinations of different signals. On the other hand, irrespective of method selected, creating animation by hand is a time consuming and costly process for people who are working in the art side. For these reasons we can use the databases which are open to everyone such as Computer Graphics Laboratory of Carnegie Mellon University. Creating a new motion from scratch by hand by using some spatial tools (such as 3DS Max, Maya, Natural Motion Endorphin or Blender) or by reusing motion captured data has some difficulties. -
Animation: Types
Animation: Animation is a dynamic medium in which images or objects are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today most animations are made with computer generated (CGI). Commonly the effect of animation is achieved by a rapid succession of sequential images that minimally differ from each other. Apart from short films, feature films, animated gifs and other media dedicated to the display moving images, animation is also heavily used for video games, motion graphics and special effects. The history of animation started long before the development of cinematography. Humans have probably attempted to depict motion as far back as the Paleolithic period. Shadow play and the magic lantern offered popular shows with moving images as the result of manipulation by hand and/or some minor mechanics Computer animation has become popular since toy story (1995), the first feature-length animated film completely made using this technique. Types: Traditional animation (also called cel animation or hand-drawn animation) was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings, first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators' drawings are traced or photocopied onto transparent acetate sheets called cels which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one against a painted background by rostrum camera onto motion picture film. -

Box 1346 Ann Arbor, Ml 48106- 1346 GLASGOW UNIVERSITY LIBRARY U3 ^coji^ \ Abstract Traditional 2D animation remains largely a hand drawn process. Computer-assisted animation systems do exists. Unfortunately the overheads these systems incur have prevented them from being introduced into the traditional studio. One such prob lem area involves the transferral of the animator’s line drawings into the computer system. The systems, which are presently available, require the images to be over- cleaned prior to scanning. The resulting raster images are of unacceptable quality. Therefore the question this thesis examines is; given a sketchy raster image is it possible to extract a cleaned-up vector image? Current solutions fail to extract the true line from the sketch because they possess no knowledge of the problem area. -
Facial Animation: Overview and Some Recent Papers
Facial animation: overview and some recent papers Benjamin Schroeder January 25, 2008 Outline Iʼll start with an overview of facial animation and its history; along the way Iʼll discuss some common approaches. After that Iʼll talk about some notable recent papers and finally offer a few thoughts about the future. 1 Defining the problem 2 Historical highlights 3 Some recent papers 4 Thoughts on the future Defining the problem Weʼll take facial animation to be the process of turning a characterʼs speech and emotional state into facial poses and motion. (This might extend to motion of the whole head.) Included here is the problem of modeling the form and articulation of an expressive head. There are some related topics that we wonʼt consider today. Autonomous characters require behavioral models to determine what they might feel or say. Hand and body gestures are often used alongside facial animation. Faithful animation of hair and rendering of skin can greatly enhance the animation of a face. Defining the problem This is a tightly defined problem, but solving it is difficult. We are intimately aware of how human faces should look, and sensitive to subtleties in the form and motion. Lip and mouth shapes donʼt correspond to individual sounds, but are context-dependent. These are further affected by the emotions of the speaker and by the language being spoken. Many different parts of the face and head work together to convey meaning. Facial anatomy is both structurally and physically complex: there are many layers of different kinds of material (skin, fat, muscle, bones). Defining the problem Here are some sub-questions to consider. -

The Traditional Arts and Crafts of Turnery Or Mashrabiya
THE TRADITIONAL ARTS AND CRAFTS OF TURNERY OR MASHRABIYA BY JEHAN MOHAMED A Capstone submitted to the Graduate School-Camden Rutgers, The State University of New Jersey In partial fulfillment of the requirements For the degree of Master of Art Graduate Program in Liberal Studies Written under the direction of Dr. Martin Rosenberg And Approved by ______________________________ Dr. Martin Rosenberg Camden, New Jersey May 2015 CAPSTONE ABSTRACT The Traditional Arts and Crafts of Turnery or Mashrabiya By JEHAN MOHAMED Capstone Director: Dr. Martin Rosenberg For centuries, the mashrabiya as a traditional architectural element has been recognized and used by a broad spectrum of Muslim and non-Muslim nations. In addition to its aesthetic appeal and social component, the element was used to control natural ventilation and light. This paper will analyze the phenomenon of its use socially, historically, artistically and environmentally. The paper will investigate in depth the typology of the screen; how the different techniques, forms and designs affect the function of channeling direct sunlight, generating air flow, increasing humidity, and therefore, regulating or conditioning the internal climate of a space. Also, in relation to cultural values and social norms, one can ask how the craft functioned, and how certain characteristics of the mashrabiya were developed to meet various needs. Finally, the study of its construction will be considered in relation to artistic representation, abstract geometry, as well as other elements of its production. ii Table of Contents Abstract……………………………………………………………………….……….…..ii List of Illustrations………………………………………………………………………..iv Introduction……………………………………………….…………………………….…1 Chapter One: Background 1.1.
