In this paper, we present a new method for segmenting a colour image into homogeneous regions. This method uses the discriminant properties of the three perceptual colour attributes : the hue H, the saturation S and the value V. In a preliminary step, each pixel is classiied according to a chromaticity degree which characterises its belonging to a colour space zone whose chromatic components ar...

A study of several methods for combining information from two classifiers in a system for the recognition of handwritten text is presented. The system uses two hidden Markov models (HMMs) per character to model columns and rows of pixels in the character image. We show that the best method of combining the results from the vertical and horizontal classifiers is simply to multiply the probabilit...

Videotext refers to text superimposed on video frames. A videotext based Multimedia Description Scheme has recently been adopted into the MPEG-7 standard. A study of published work in the area of videotext extraction and recognition reveals that, despite recent interest, a reliable general purpose video character recognition (VCR) system is yet to be developed. In our research and development o...

To edit or create the animation of a 3D character model has always been an important but time-consuming task, since the animator usually needs to set up the character’s skeleton, paint its binding weights, and adjust its key-poses. Hence, we propose an animation transfer system in this paper to take a well-edited character animation as the input. Then, the system can transfer the skeleton, bind...

s Service. This is issued biweekly, and includes the titles, authors' names, and bibliographic references of currently published articles of chemical interest. The issue used was No. 1, 1971, dated 11 January. A typical entry from the issue is shown in Fig. 1; the bibliographic reference is given as the ASTM Coden. The titles are recorded in upper-case characters. An occasional artefact arises ...

People tend to associate the abstract concepts of "good" and "bad" with their fluent and disfluent sides of space, as determined by their natural handedness or by experimental manipulation (Casasanto, 2011). Here we investigated influences of spatial perspective taking on the spatialization of "good" and "bad." In the first experiment, participants indicated where a schematically drawn cartoon ...

We present space lower bounds for online pattern matching under a number of different distance measures. Given a pattern of length m and a text that arrives one character at a time, the online pattern matching problem is to report the distance between the pattern and a sliding window of the text as soon as the new character arrives. We require that the correct answer is given at each position w...
