Mosaic based representations of video sequences and their applications

ABSTRACT
Recently, there has been a growing interest in the use of mosaic images to
represent the information contained in video sequences. The paper
systematically investigates how to go beyond thinking of the mosaic simply
as a visualization device, but rather as a basis for efficient representation
of video sequences. We describe two different types of mosaics called the
static and the dynamic mosaic that are suitable for different needs and
scenarios. We discuss a series of extensions to these basic mosaics
to provide representations at multiple spatial and temporal resolutions and
to handle 3D scene information. We describe techniques for the basic elements
of the mosaic construction process, namely alignment, integration, and
residual analysis. We describe several applications of mosaic representations
including video compression, enhancement, enhanced visualization, and other
applications in video indexing, search, and manipulation.

12/18 meeting

Target :
靜靜 靜動 動靜 動動

短期目標 :
1. 加速版完成
2. 找相關paper

Question :
1. 太慢 ??
2. real time ??
3. 資料要放哪裡 ?? 可能很大

-----------------------------
mosaic(I1,I2,LastIM,ColorIndex) -> IMap ;
gen_img(IMao,FileIndex,bsh,bsw) -> Img ;
