BACKGROUND Advocating the need to adopt more self-management policies has brought with it an increasing demand for information about living with and making decisions about long-term conditions, with a significant potential for using cartoons. However, the purposeful use of cartoons is notably absent in many areas of health care as is evidence of their acceptability to patients and lay others. T...

A difficult task of a sketch understanding system is that it should always try to balance between the drawing freedom and the complexity of recognition. Most online existing works are based on the assumption that people will not start to draw a new symbol before the last one has been finished. As obviously it is not always the case, we propose in this paper a method which relaxes this constrain...

Sketching is a natural way of input that provides an effective means of illustration. A sketch consists of multiple strokes that can be captured by pen-based devices to be stored in a database for future retrieval. In our prior work, we proposed a sketch retrieval method that is suitable for whole matching. However, the problem gets complicated if the retrieval is performed for partially matche...

Recent work in non-photorealistic rendering has produced results comparable to hand-drawn artistic images. Inspiration for such techniques has come from many traditional artistic techniques, such as pen-and-ink, to depict tone, depth, and shape. These techniques can create visually appealing images and increase understanding as is evident in their use in medical textbooks, popular science, etc....

This paper presents a compact and efficient shape signature that can be applied to shape retrieval from handdrawn sketches. The two proposed invariant features that constitute our affine invariant signature are: (a) angle between spoke vectors, and (b) cumulated normalized area between consecutive spoke vectors. The signature can be computed efficiently from an input shape and supports fast sim...

In this paper we present an approach for synthesising and editing cartoon fire series based on hand-drawn samples. Our approach first extracts outlines of hand-drawn cartoon fire series and, based on the central reference skeleton, synthesises fire of arbitrary length by high level control on flame skeletons. With our approach users may edit cartoon fire series to achieve effects such as fire s...

Abstract In hand-drawn sketch recognition, the traditional deep learning method has problems of insufficient feature extraction and low recognition rate. To solve this problem, a new algorithm based on dual-channel convolutional neural network is proposed. Firstly, preprocessed to get smooth sketch. The contour obtained by algorithm. Then, are used as input image CNN. Finally, fusion carried ou...

Two experiments investigated whether motion metaphors for time affected the perception of spatial motion. Participants read sentences either about literal motion through space or metaphorical motion through time written from either the ego-moving or object-moving perspective. Each sentence was followed by a cartoon clip. Smiley-moving clips showed an iconic happy face moving toward a polygon, a...
