'To interlace or not to interlace' is a hot issue currently. Traditionally interlace has been part of the video standard as it reduces the transmission and display demands, while hardly affecting the perceived quality of the pictures.

With the current explosion of new video formats due to emerging technologies as multimedia PC's, videotelephony and flat matrix display the question whether or not interlace is a relict from the past is more relevant than ever.

This book provides a broad overview of advanced motion estimation and de-interlacing techniques to enable a profound scientific basis for answering the above question. An extensive evaluation of the algorithms, including many screen photographs is an imt part of the book. But also system questions, such as whether interlace is a good choice in combination with modern video compression methods (MPEG), and which currently would be the optional choice for a display format are extensively treated.

The combination of scientific profoundness and completions, with the focus on practical hot issues, makes the book unique in its kind.
