摘要：

The　position　of　seam　center　was　got　with　template　match　algorithm.　First　seam　template　was　acquired　through　wavelet　transform,　then　the　template　was　shifted　in　subsequent　seam　image　and　correlation　coefficients　were　calculated　accordingly,　the　column　corresponding　to　the　max　correlation　coefficient　was　taken　as　seam　center　position　of　subsequent　seam　image.　The　seam　image　is　processed　with　TDS642EVM　since　digital　signal　processor　(DSP)　has　advantages　in　digital　signal　processing.　Principle　of　2-D　wavelet　transform　algorithm　was　analyzed,　then　wavelet　transform　programs　on　DSP　are　developed.　At　last,　example　of　processing　pipeline　seam　image　with　TDS642EVM　was　given.
