Buried pipeline mapping from satellite images

ELECTRONICS & COMMUNICATION ENGINEERING JOURNAL 2002年第4期14卷 143-154页

作者： Petrou, M Gracia, I Univ Surrey Sch Elect Comp & Math Guildford GU2 7XH Surrey England Univ Jaume Dept Comp Sci Castellon 12071 Spain

A semi-automatic method for the detection and tracking of buried pipelines under a variety of surface coverages is presented and its performance in experiments reported, In high 1 m resolution aerial or satellite images, the buried structures manifest themselves as bands a few pixels wide having contrast and texture changes of the overground growth. Some statistical nonlinear filters are proposed for the detection of such wide linear features, and they are used for the detection of pipeline routes. The pipeline routes are then tracked by exploiting their lateral continuity.

Signal-dependent wavelet transform and application to lossless image compression

引用

ELECTRONICS LETTERS 2002年第4期38卷 170-172页

作者： Yoo, H Joeng, J Hanyang Univ Dept Elect Commun Engn Seoul 133791 South Korea

A signal-dependent wavelet transform based on the lifting scheme is proposed. The transform can be made reversible (i.e. an integer-to-integer transform). The reversible transform. followed by arithmetic coding, is applied to lossless image compression. Simulation results indicate that the proposed method is superior to the S + P method.

Two-step motion estimation algorithm for large search range using outlier pixel exclusion

引用

ELECTRONICS LETTERS 2002年第2期38卷 68-69页

作者： Lee, S Chae, SI Ewha Womans Univ Dept Informat Elect Engn Seodaemun Gu Seoul 120750 South Korea Ewha Womans Univ Sch Elect Engn Kwanak Gu Seoul 120750 South Korea

A new two-step motion estimation algorithm is proposed for large search range. It exploits minimum mean-absolute-error quantisation and outlier pixel exclusion to reduce performance degradation. With respect to the full search algorithm, the hardware cost is reduced to 1/144 with similar peak signal-to-noise ratio performance when the search range is +/- 128 x +/- 128.

Adaptive motion-compensated frame rate up-conversion

引用

ELECTRONICS LETTERS 2002年第10期38卷 451-452页

作者： Lee, SH Yang, S Samsung Elect Co Ltd Digital Media R&D Ctr Suwon 442742 South Korea

A frame rate up-conversion algorithm using the adaptive motion compensation that reduces the blocking artifacts due to block-based processing is proposed. The proposed method uses the motion analysis to determine the type of motion and applies the motion-compensated interpolation (MCI) adaptively. When the MCI is applied, multiple motion trajectories are considered in order to increase the accuracy of the MCI. Experiment results indicate good performance of the proposed MCI scheme with significantly reduced blocking artifacts.

作者： Hu, JQ Huang, JW Huang, DR Shi, YQ Sun Yat Sen Univ Sch Informat Sci & Technol Guangzhou 510275 Peoples R China New Jersey Inst Technol Dept Elect & Comp Engn Newark NJ 07102 USA

A new discrete wavelet transform-based image fragile watermarking scheme exploiting the features of the human visual system is presented. Fusion of multi-resolution tamper detections, and mathematical morphology operations are developed for accurate tamper detection. As a result, malicious tamper and the tampered regions can be detected, while toleration towards high quality lossy image compression is achieved.

ELECTRONICS LETTERS 2002年第18期38卷 1023-1023页

作者： Zeng, ZY Lu, XD Shanghai Jiao Tong Univ Dept Comp Sci & Engn Shanghai 200030 Peoples R China

A large and useful subset of image processing applications can be characterised using data parallel iterative synchronous algorithms. A partitioning and co-scheduling algorithm with minimum task's finish time is presented. One important rational characteristic of this algorithm is that it has considered the communication overhead.
