Boundary artefact reduction using odd tile length and the low pass first convention (OTLPF)

It is well known that tile boundary artefacts occur in lossy wavelet-based image coding. The base model of the JPEG2000 standard (ie JPEG2000 Part I) suffers from these artefacts, being a wavelet-based coding system. This paper analyses the tile boundary problems of JPEG2000 Part I and presents a novel method for reducing these tile boundary artefacts. This method has recently been adopted as part of the JPEG 2000 Verification Model 9.0 and as an addition to Part II of the JPEG2000 standard.
