The diffusion of mobile devices and the development of their services and applications are connected with the possibility to communicate anytime and anywhere according to a natural approach, which combines different modalities (speech, sketch, etc.). A natural communication approach, such as sketch-based interaction, frequently produces ambiguities. Ambiguities can arise in sketch recognition p...

It is difficult to represent video scenes using keywords. Therefore, in video retrieval, it is not easy to design keyword queries that enable a viewer to represent and find the desired scenes. In this paper, we proposed a video retrieval system that uses handwriting sketches as queries. The user queries the system by drawing a handwriting sketch that includes object shape and motion. The propos...

Graphic sketch representations are effective for representing sketches. Existing methods take the patches cropped from sketches as graph nodes, and construct edges based on sketch's drawing order or Euclidean distances canvas. However, of a may not be unique, while semantically related parts far away each other In this paper, we propose an order-invariant, semantics-aware method graphic represe...

We investigate the averaging problem in cosmology as the problem of introducing a distance between spaces. We first introduce the spectral distance, which is a measure of closeness between spaces defined in terms of the spectra of the Laplacian. Then we define SN , a space of all spaces equipped with the spectral distance. We argue that SN can be regarded as a metric space and that it also poss...

Sketch recognition is the automated understanding of hand-drawn diagrams. Despite the prevalence of keyboards and mice, hand-drawings still pervade in education, design, and other diagrams. This full day tutorial explains why sketch recognition is important, the underlying algorithms, how sketch recognition can be used in traditional interfaces, and the field’s experiences with sketch recogniti...

The Manatee corpus management system on which the Sketch Engine is built is efficient, but unable to harness the power of today’s multiprocessor machines. We describe a new, compatible implementation of Manatee which we develop in the Go language and report on the performance gains that we obtained.

Inputting written Chinese, unlike written English, is a non-trivial operation using a standard keyboard. To accommodate this operation, numerous existing phonetic systems using the Roman alphabet were adopted as a means of input while still making use of a Western keyboard. With the growing prevalence of computing devices capable of pen-based input, naturally sketching written Chinese using a p...
