High Quality Image Orthicon

High quality image resizing

An increasing amount of display devices with fixed sizes call for an adaptive strategy for optimal display. For this purpose, content aware image resizing techniques are developed. Previous works mainly lay their attention on the shrinkage operation of the examined image. Less efforts are paid on the expansion manipulation. Though some literatures claim an extension of their shrinkage operation...

High quality document image compression with "DjVu"

We present a new image compression technique called \DjVu " that is speci cally geared towards the compression of high-resolution, high-quality images of scanned documents in color. This enables fast transmission of document images over low-speed connections, while faithfully reproducing the visual aspect of the document, including color, fonts, pictures, and paper texture. The DjVu compressor ...

Image mosaicing: Create High Quality Panoramic Multi-spectral Image by

In computer graphics and virtual reality, multi-spectral and panoramic images are needed. To get a panoramic multi-spectral images, the approach to use a filter transmitting spectral bands are spatially varying is proposed. A filter is attached to an 8-bit black/white camera. Then take images ( there is no parallax).Each scene points are taken many times in different spectral band. After that m...

Image Quality Subjective Evaluation for Very High-rate Image Compression

The paper is devoted to the subjective image quality evaluation for selected highly efficient compression standards. The experimental verification was done for the seven-segment display image test.
