Abstract AR
قدمت- في هذه الورقة - خوارزمية ضغط إشارة مرئيvideo، قابلة للمقارنة مع التقنيات المعيارية عند معدلات بت منخفضة.
حيث تم ضم تعويض حركة القالب التراكبي(OBMC) إلى تحويل مويجات منفصلة متبوعة بتكمي لويد_ماكس و بنية مويجات بدون شجرة .(ZTW) و تتمثل السمة الإبداعية في طريقة الترميز هذه في إدماج متجه حالة تكمي تسلسلي محدود (HFSVQ) مع ZTWلتشفير معاملات المويجات المكماة .و يظهر مشفر المرئي المقترح (ZTW-HFSVQ) أداء أفضل من تشفير 4MPEG- و تشفير انتروبيا بدون شجرة .(ZTE)
Abstract EN
A video compression algorithm comparable to the standart techniques at low bit rates is presented in this paper.
The overlapping block motion compensation (OBMC) is combined with discrete wavelet transform which followed by Lloyd–Max quantization and zerotree wavelet (ZTW) structure.
The novel feature of this coding scheme is the combination of hierarchical finite state vector quantization (HFSVQ) with the ZTW to encode the quantized wavelet coefficients.
It is seen that the proposed video encoder (ZTW–HFSVQ) performs better than the MPEG-4 and Zerotree Entropy Coding (ZTE).
