The goal of the thesis is to examine how quadtrees are used in video compression. This thesis gets familiar with datacompression and saving of space with quadtree and octree data structures and how quadtrees are used in HEVC video compression. Data compression is categorized into two categories: lossy and lossless data compression, followed by quadtree and its expansions and variants such as octree, R -tree and kd -tree definitions and examples of their usage in different applications. In this thesis, it is observed that HEVC video compression uses quadtrees for example to create prediction for observable frame.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-03-16T09:57:22Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-03-16T09:57:22Z (GMT).
