JPEG is a lossy compression standard for digital images. The JPEG
encoding process lets users trade off reduced compressed filesize for
degraded image quality.
We have developed a JPEG Quality Transcoder (JQT) that converts a
JPEG image file that was encoded with low image quality to a larger
JPEG image file with reduced visual artifacts, without access to the
original uncompressed image.
In this website, we show how JQTs can be used in networked systems
while maintaining compatibility with the JPEG standard.
- Reduce bandwidth while maintaining perceptual quality.
- Enhance perceptual quality at a constant bandwidth.
