Signal processing for enhanced image representation Prof. dr. ir. Gerard de Haan

The introduction of digital signal processing in consumer video equipment enabled various techniques to enhance the image representation. This paper provides an overview of techniques developed for high-end television sets in Philips Research Laboratories Eindhoven over roughly the last decade. Three categories of enhancement are distinguished: enhancements required to improve poor input video streams, to repair unfavourable display properties, and to cope with mismatches between source and display format. There will be some emphasis on the enhancements in the last category, as Philips Research took the lead in this area. Also the developments in an important enabling technology, motion estimation, are briefly discussed.
