A recent trend in ultra low bit-rate speech coding is based on segment quantization by unit-selection principle using large continuous codebooks as a unit database. We show that use of such large unit databases allows speech to be reconstructed at the decoder by using the best unit’s residual itself (in the unit database), thereby obviating the need to transmit any side information about the re...

High efficiency video coding (HEVC) has been finalized as the most widely utilized standard, jointly developed by ITU-T, VCEG, and MPEG. In HEVC, quad-tree structure of unit partition is one substantial modules provides significant gains following huge time. this paper, a rate–distortion-based network (RDNet) proposed to make decisions based on statistical features. RDNet composed prediction su...

HEVC (High Efficiency Video Coding) is the next-generation video coding standard, which introduced many new technologies such as tree structure coding unit and a variety of intra prediction mode. Compared with H.264/AVC, HEVC has achieved higher coding efficiency but requires a very high computational complexity. So this paper proposes a fast algorithm through early termination of the CU (Codin...

The latest video coding standard, high efficiency video coding (HEVC) achieves high coding efficiency by employing a quadtree-based coding unit (CU) block partitioning structure which allows recursive splitting into four equally sized blocks. At each depth level, each CU is partitioned into variable sized blocks of prediction units (PUs). However, the determination of the best CU partition for ...

the purpose of the present study was to assess job stress in medical records personnel. 117 females and 78 males were assessed by osipow et al.'s job roles inventory. data were analyzed by descriptive statistics and chi-square test. the findings indicated that the physical environment was the main source of stress for the staff of the four different units of the medical records department,...

In this paper we propose an adaptive Joint Source and Channel Coding (JSCC) associated with adequate modulation algorithm to provide a near channel capacity video transmission rate to achieve better system performance. In the proposed algorithm we apply MPEG-2 video coding scheme, and turbo channel coding technique as well as BPSK/QPSK for modulation method. Rates assigned to MPEG-2 source codi...

In the present paper we consider an analogous problem, but instead of using the binary number system as Hewgill did, we interpret every second row of modulo 2 reduced Pascal’s triangle in the Fibonacci number system. Moreover, we are interested about the whole family of sequences where the even indexed rows specify the most significant digits (“fibits”) of the Zeckendorf expansion of an integer...

We built a 12.4 mm × 12.4 mm, 45-nm CMOS, chip that integrates eight 648-MHz general purpose cores, two matrix processor (MX-2) cores, four flexible engine (FE) cores and media IP (VPU5) to establish heterogeneous multi-core chip architecture. The general purpose core had its IPC (instructions per cycle) performance enhanced by adding 32-bit instructions to the existing 16-bit fixed-length inst...
