    Abstract: Progressive image transmission (PIT) transmits the most significant portion of a
    picture, followed by its less important portions. The mechanism can be used in Webbased
    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 test several decomposition mechanisms. The contribution results in an
    adaptive image transmission scheme, which takes the differences of picture portions into
    consideration. Moreover, this study tested 200 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.
