    摘要: Progressive image transmission (PIT) transmits the most significant portion of a picture, followed
    by its less important portions. The mechanism can be used in Web-based applications while users are
    browsing images. However, most PIT methods use the same pixel interpolation scheme for the entire
    picture, without considering the differences among image blocks. This paper analyzes the efficiency of
    pixel interpolation schemes and tests several decomposition mechanisms. The contribution results in an
    adaptive image transmission scheme, which takes the differences of picture portions into consideration.
    This study tested 1500 pictures in different categories and parameters. In consequence, the overall bit
    rates can be reduced significantly with good PSNR values and user satisfaction. The visual result is
    superior to progressive JPEG on both objective (quantitative) and subjective (human) measures. An
    error recovery procedure is also implemented in case that the transmitted pictures need to be fully
    recovered.
