1	2-d Mesh-based Motion Estimation And Video Object Manipulation Kaval, Huseyin 01 September 2007 (has links) (PDF) Motion estimation and compensation plays an important role in video processing applications. Two-dimensional block-based and mesh-based models are widely used in this area. A 2-D mesh-based model provides a better representation of complex real world motion than a block-based model. Mesh-based motion estimation algorithms are employed in both frame-based and object-based video compression and coding. A hierarchical mesh-based algorithm is applied to improve the motion field generated by a single-layer algorithm. 2-D mesh-based models also enable the manipulation of video objects which is included in the MPEG-4 standard. A video object in a video clip can be replaced by another object by the use of a dynamic mesh structure. In this thesis, a comparative analysis of 2-D block-based and mesh-based motion estimation algorithms in both frame-based and object-based video representations is performed. The experimental results indicate that a mesh-based algorithm produces better motion compensation results than a block-based algorithm. Moreover, a two-layer mesh-based algorithm shows improvement over a one-layer mesh-based algorithm. The application of mesh-based motion estimation and compensation to video object replacement and animation is also performed.
2	Secondary World: The Limits of Ludonarrative Dannelly, David 01 January 2014 (has links) Secondary World: The Limits of Ludonarrative is a series of short narrative animations that are a theoretical treatise on the limitations of western storytelling in video games. The series covers specific topics relating to film theory, game design and art theory: specifically those associated with Gilles Deleuze, Jean Baudrillard, Jay Bolter, Richard Grusin and Andy Clark. The use of imagery, editing and presentation is intended to physically represent an extension of myself and my thinking process and which are united through the common thread of my personal feelings, thoughts and experiences in the digital age.
