Este artigo apresenta uma nova abordagem para analisar o sangramento de cores causado pela compressão de imagens. Isto é conseguido isolando dois componentes do sangramento colorido e avaliando esses componentes separadamente. Embora esses componentes específicos do sangramento de cores não tenham sido estudados com grande detalhe no passado, com o uso de um padrão de teste sintético – semelhante às barras de cores usadas para testar transmissões de televisão analógicas – isolamos e avaliamos com sucesso: “ desfoque de cor" e "toque de cor", como dois componentes separados do artefato de sangramento de cor. Também desenvolvemos métricas para esses artefatos e testamos essas métricas derivadas em uma série de testes destinados a testar o desempenho de reprodução de cores de um codec JPEG e de um codec JPEG2000 – ambos implementados pelo desenvolvedor IrfanView. Os algoritmos desenvolvidos para medir essas métricas de artefatos provaram ser ferramentas eficazes para avaliar e comparar o desempenho de codecs semelhantes ou de diferentes implementações dos mesmos codecs.

Abstract: This paper presents a novel approach of analysing colour bleeding caused by image compression. This is achieved by isolating two components of colour bleeding, and evaluating these components separately. Although these specific components of colour bleeding have not been studied with great detail in the past, with the use of a synthetic test pattern -- similar to the colour bars used to test analogue television transmissions -- we have successfully isolated, and evaluated: "colour blur" and "colour ringing," as two separate components of colour bleeding artefact. We have also developed metrics for these artefacts, and tested these derived metrics in a series of trials aimed to test the colour reproduction performance of a JPEG codec, and a JPEG2000 codec -- both implemented by the developer IrfanView. The algorithms developed to measure these artefact metrics proved to be effective tools for evaluating and benchmarking the performance of similar codecs, or different implementations of the same codecs.
