Algoritma berasaskan wavelet untuk pemampatan video boleh skala diterangkan, dengan tumpuan utama diletakkan pada pengurangan lebar jalur memori dan pelaksanaan VLSI yang cekap. Algoritma yang dicadangkan menggunakan skema penguraian subband 2-D yang diubah suai bersama-sama dengan a zerotree separa cari pengekodan Embedded Zerotree Wavelet yang cekap. Percubaan dengan prestasi algoritma yang dicadangkan berbanding dengan DWT konvensional, MPEG-2 dan JPEG menunjukkan bahawa kualiti imej algoritma yang dicadangkan secara konsisten lebih baik daripada JPEG, dan skema kami juga boleh mengatasi prestasi MPEG-2 dalam sesetengah kes, walaupun ia tidak mengeksploitasi lebihan antara bingkai. Walaupun prestasi rendah berbanding DWT konvensional, algoritma yang dicadangkan mencapai pengurangan ketara keperluan memori DWT, meningkatkan keseimbangan yang munasabah antara kos pelaksanaan dan kualiti imej.

Abstract: A wavelet based algorithm for scalable video compression is described, with the main focus put on memory bandwidth reduction and efficient VLSI implementation. The proposed algorithm adopts a modified 2-D subband decomposition scheme in conjunction with a partial zerotree search for efficient Embedded Zerotree Wavelet coding. The experiment with the performance of the proposed algorithm in comparison with that of conventional DWT, MPEG-2, and JPEG demonstrates that the image quality of the proposed algorithm is consistently superior to that of JPEG, and our scheme can even outperform MPEG-2 in some cases, although it does not exploit the inter-frame redundancy. In spite of the performance inferiority to the conventional DWT, the proposed algorithm attains significant reduction of DWT memory requirements, enhancing a reasonable balance between implementation cost and image quality.
