This paper presents an efficient scheme for detecting copy-move forgery tampering attacks. The copy-move forgery attack is defined as a region of an image is replaced by a copy of other region in the same image. This detection is useful for malicious modifying an image. The proposed scheme improves previous cluster expanding block scheme to clustering by mean and variance for reducing the computation...
This paper proposes a dual mode video decoder with 4-level temporal/spatial scalability and 32/64-bit adjustable memory bus width. A design automation environment for simulation and verification is established to automatically verify the correctness and completeness of the proposed design. Using a 0.13 um CMOS technology, it comprises 439Kgates/10.9KB SRAM and consumes 2~328mW in decoding CIF~HD1080...
The first dual mode video decoder with 4-level temporal/spatial scalability and 32/64-bit adjustable memory bus width is proposed. A design automation environment of simulation and verification is established to automatically verify the correctness and completeness of the proposed design. Using a 0.13 ??m CMOS technology, it comprises 439 K gates/10.9 KB SRAM and consumes 2~328 mW in decoding CIF~HD1080...
This demo proposes a dynamic quality-scalable H.264 video encoder that has been published in ISSCC2007 [8]. Exploiting parameterized algorithms for motion estimation and intra prediction, the proposed design can dynamically configure the encoding modes with the design trade-off between power consumption and video quality for various video applications.
This paper presents a high throughput VLSI architecture for H.264/AVC in-loop de-blocking filter (ILF) supporting baseline, main, and high profile (BP/MP/HP) video decoding targeted at HDTV applications. We develop a 4times4/8times8 filter and a buffer management scheme to perform the various coding tools in H.264 de-blocking filter for supporting the coding tools of picture adaptive frame/field (PAFF)...
Due to the fast growth of multimedia content, the digital preservation emerges as an important technology that prolongs the life of digital objects. For audio-visual contents, we face the obsolescence problem in both supporting hardware/software and data representation formats. Migration strategy is a solution for achieving high-quality archival and easy access. In this paper, we investigate the concepts...
Content-based image retrieval (CBIR) has been adopted as a complementary technique to the keyword-based image search. Relevance feedback (RFB) is considered as an effective means to bridge the gap between the designated features and the run-time semantics on a CBIR system. Like many other interactive system, a good user interface, which in RFB is mainly the presentation of the query results, is an...
