In this paper we propose a method for sketch-based image retrieval. Sketch is a magical medium which is capable of conveying semantic messages for user. It’s in accordance with user’s cognitive psychology to retrieve images with sketch. In order to narrow down the semantic gap between the user and the images in database, we preprocess all the images into(More)
In this paper, we present a new sketch-based system - KnitSketch, to improve the efficiency of process planning for knitting garments at an early design stage. The KnitSketch system utilizes sketching interface with the pen-paper metaphor and users only need to draw outlines of different parts of the garment. Based on sketching understanding, the system(More)
3-D CAD models are an important digital resource in the manufacturing industry. 3-D CAD model retrieval has become a key technology in product lifecycle management enabling the reuse of existing design data. In this paper, we propose a new method to retrieve 3-D CAD models based on 2-D pen-based sketch inputs. Sketching is a common and convenient method for(More)
Authoring context-aware, interactive video representation is usually a complex process. A user-friendly multimedia authoring environment is thus solicited to explore and express users' design ideas efficiently and naturally. In this paper we present a sketch-based two-layer representation, called scene structure graph (SSG), to facilitate the video(More)
With the rapid progress of the network and mobile techniques, mobile devices such as mobile phones and portable devices, have become one of the most important parts in common life. Efficient techniques for watching, navigating and sharing videos on mobile devices collaboratively are appealing in mobile environment. In this paper, we propose a novel approach(More)
Video summarization aims to give a condensed presentation of video content, facilitating users to efficiently and effectively browse videos and obtain specific information in a short time following users' attention. In this paper, we propose a novel method to generate personalized sketch summarization supporting sketch interaction that is characterized for(More)
Visualizing and communicating insights through maps offers an intuitive and familiar way to explore large-scale dynamic relational data. In this paper, we present VideoMap, which is a novel approach for presenting and interacting with relational video content by taking advantage of the map metaphor. VideoMap employs a metaphor to visualize video content by(More)
EasyToy is an industrial plush toy design system for novices. Editable sketching curves combine the advantages of free-form strokes and the controllability of B-spline curves. Users can continuously edit each curve to refine designs. EasyToy provides a small set of simple tools with which users can easily construct sophisticated toy models comparable to(More)

With the rapid growth of video resources, techniques for efficient organization of video clips are becoming appealing in the multimedia domain. In this article, a sketch-based approach is proposed to intuitively organize video clips by: (1) enhancing their narrations using sketch annotations and (2) structurizing the organization process by gesture-based(More)
