In this paper we present a C-1 interpolation scheme on a triangle. The interpolant assumes given values and one order derivatives at the vertices of the triangle. It is made up of partial interpolants blended with corresponding weight functions. Any partial interpolant is a piecewise cubics defined on a split of the triangle, while the weight function is just the respective barycentric coordinate. Hence the interpolant can be regarded as a piecewise quartic. We device a simple algorithm for the evaluation of the interpolant. It's easy to represent the interpolant with B-net method. We also depict the Franke's function and its interpolant, the illustration of which shows good visual effect of the scheme.

With the wide use of color in many areas, the interest on the color perception and processing has been growing rapidly. An important topic in color image processing is the development of efficient tools capable of filtering images without blurring them and without changing their original chromatic contents. In this paper, a new technique reducing noise of color image is developed. A class of color-scale morphological operations is introduced, which extend mathematical morphology to color image processing, representing a color image as a vector function. The correlation between color components is utilized to perform noise removal. Color-scale morphological niters with multiple structuring elements (CSMF-MSEs) are proposed. Their properties are discussed and proved. Experimental results show that CSMF-MSEs are suitable and powerful to eliminate noise and preserve edges in color image because of efficient utilization of inherent correlation between color components, and they perform better than vector

Considering the fact that hoarse speech is usually caused by pathological changes of vocal cords, and its motion state is reflected by glottal waveform, we present a new method of research on hoarse speech based on dissymmetric four-mass model of vocal cords and glottal wave analysis-synthesis ill this paper. By linking hoarse speech waveform with glottal wave and the vocal cord model, the characteristic parameters of normal speech and hoarse speech before and after laryngeal operation are studied. The parameters of glottal wave periodicity and vocal cord symmetry of hoarse speech are compared with those of normal speech. It is applied to analyzing the relations between model parameters and hoarse mechanism in pathology and physiology. Experimental results show that this new method can unveil the relations between acoustic features and pathological causes of hoarse speech, providing theoretical and experimental bases both for diagnosing laryngeal diseases non-contactly and for improving the tone quality of hoarse speech.
