As new computer architectures are developed to exploit large-scale data-level parallelism, techniques are needed to retarget legacy sequential code to these platforms. Sequential programming languages force programmers to include sequential artifacts in their code, particularly with respect to how the source code expresses data references (generally assuming a linear address space). In contrast...

Seam carving is a content-aware multimedia retargeting technique to adaptively resize multimedia data for different display sizes. However, it can also be used to remove objects from digital object or video for malicious purposes. In this paper, a forensics hash-based tampering detection and localization approach is proposed for seam carving-based video retargeting. It extracts the invariant Sp...

Pixel-per-processing element (PPE) ratio – the amount of image data directly mapped to each processing element, has a significant impact on the area and energy efficiency of embedded SIMD architectures for image processing applications. This paper quantitatively evaluates the impact of PPE ratio on system performance and efficiency for focal-plane SIMD image processing architectures by comparin...

Computer-generated character animation, where human or anthropomorphic characters are animated to tell a story, holds tremendous potential to enrich education, human communication, perception, and entertainment. However, current animation procedures rely on a time consuming and difficult process that requires both artistic talent and technical expertise. Despite the tremendous amount of artistr...

Fish animation generation is an interesting topic since it plays an important role in building virtual underwater worlds. Accurate motion capture and flexible retargeting of fish is difficult, in particular with the challenges of underwater marker attachment and feature description for soft bodies. Little research into this problem has been published and real-time fish motion retargeting with a...

We present a novel semantic model for human head defined with neural radiance field. The 3D-consistent consist of set disentangled and interpretable bases, can be driven by low-dimensional expression coefficients. Thanks to the powerful representation ability field, constructed represent complex facial attributes including hair, wearings, which not represented traditional mesh blendshape. To co...

We introduce a single unifying framework for a wide range of content-aware image warping tasks using a finite element method (FEM). Existing approaches commonly define error terms over vertex finite differences and can be expressed as a special case of our general FEM model. In this work, we exploit the full generality of FEMs, gaining important advantages over prior methods. These advantages i...

Saliency detection is an important yet challenging task in computer vision. In this report we investigate the use of sparse coding over redundant dictionary for saliency detection. We attempt to present a small fraction of the growing knowledge regarding sparse representation over redundant dictionary and discuss some potential usage of this powerful tool for saliency detection task. We propose...

In this paper, we introduce an interactive method suitable for retargeting both 3D objects and scenes. Initially, the input object or scene is decomposed into a collection of constituent components enclosed by corresponding control bounding volumes which capture the intra-structures of the object or semantic grouping of objects in the 3D scene. The overall retargeting is accomplished through a ...

Performance is a critical issue in Data Warehouse systems (DWs), due to the large amounts of data manipulated, and the type of analysis performed. A common technique used to improve performance is the use of pre-computed aggregate data, but the use of aggregates must be transparent for DW users. In this work, we present MF-Retarget, a query retargeting mechanism that deals with both conventiona...
