Video coding standards, such as MPEG-4 Part II and H.264/AVC, follow a block-based hybrid coding design which employs inter picture prediction to exploit temporal dependency and transform coding to exploit spatial dependency. This paper presents a video encoder preprocessing method which is based on transform and quantization to improve coding efficiency(More)
In an effort to boost the power densities of solid oxide fuel cells (SOFCs) operating at intermediate temperatures (600-750 °C), novel powder synthesis methods have been studied with the goal of increasing the three-phase boundary region of the anode. Porous anodes composed of Ni and Ce0.8Gd0.2O1.9 (GDC) cermet are commonly studied in SOFCs, but the cell(More)
Video coding standard H.264/AVC employs zig-zag scan and field scan to map transform coefficients from two dimensional matrix to one dimensional array. The zig-zag scan is used for transform coefficients in frame macroblocks (MBs), and the field scan is used in field MBs. This paper presents a most probable scan mode (MPSM) decision for H.264 inter picture(More)
