Motion vector correction based on the pattern-like image analysis
收藏 引用
IEEE TRANSACTIONS ON CONSUMER ELECTRONICS 2003年 第3期49卷 479-484页
作者: Lee, SH Kwon, O Park, RH Samsung Elect Co Ltd DTV R&D Grp Visual Display Div Digital Media Network Business Suwon South Korea Sogang Univ Dept Elect Engn Seoul South Korea
In this paper, we propose a motion vector correction algorithm to correct the erroneous motion vectors due to the failure of conventional motion estimation (ME) based on block matching algorithm (BM,4). The proposed m... 详细信息

ELECTRONICS LETTERS 2000年 第4期36卷 309-310页
作者: Peacock, AM Matsunaga, S Renshaw, D Hannah, J Murray, A Univ Edinburgh Dept Elect Engn Edinburgh EH9 3JL Midlothian Scotland
An important problem when using the block matching algorithm to track objects is how to update the reference block to take account of the changing target appearance. A variety of update strategies are reported and com... 详细信息

ELECTRONICS LETTERS 2002年 第18期38卷 1020-1021页
作者: Suh, JW Ho, YS Kwangju Inst Sci & Technol Dept Informat & Commun Kwangju 500712 South Korea
A new motion vector recovery algorithm based on optical flow is proposed. Optical flow fields are very similar to the true motion and can be used to recover three-dimensional motion information. Experimental results o... 详细信息

A fast full search motion estimation algorithm using sequential rejection of candidates from multilevel decision boundary
收藏 引用
IEICE TRANSACTIONS ON COMMUNICATIONS 2002年 第1期E85B卷 355-358页
作者: Kim, JM Ahn, BH KBS Tech Res Inst Yongdeungpo Gu Seoul 150790 South Korea K JIST Dept Mechatron Puk Gu Kwangju 500712 South Korea
We propose a new and fast full search (FS) motion estimation algorithm for video coding. The computational reduction comes from sequential rejection of impossible candidates with derived formula and subblock norms. Ou... 详细信息

2nd International Conference on Image and Graphics
作者: Brad, R Letia, IA Lucian Blaga Univ Sibiu Comp Sci Dept Sibiu 2400 Romania
The estimation of cloud motion from a sequence of satellite images can be considered a challenging task due to the complexity of phenomena implied. Being a non-rigid motion and implying non-linear events, most motion ... 详细信息

Conference on Visual Communications and Image Processing 2001
作者: Park, SG Jeong, DS Inha Univ Dept Elect Engn Nam Gu Inchon South Korea
In this paper, we propose a fast adaptive diamond search algorithm(FADS) for block matching motion estimation. Many fast motion estimation algorithms reduce the computational complexity by the UESA(Unimodal Error Surf... 详细信息

IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS 2001年 第6期E84D卷 760-762页
作者: Shin, DS Kwak, NJ Kwon, HB Ahn, JH Chungbuk Natl Univ Sch Elect & Elect Engn Dept Comp & Commun Engn Visual Commun Lab Chonju 361763 Chungbuk South Korea Gimpo Coll Dept Informat & Commun Engn Kimpo 415870 Kyounggi South Korea
In this paper, we propose a multi-level block matching algorithm using motion information in blocks. In the proposed algorithm, the block-level is decided by the motion degree in the block before motion searching proc... 详细信息
