The purpose of this paper is to investigate the realization of the [nasal] contrast in French by performing an acoustic analysis of naturally spoken nasal and oral vowels, and by carrying out discriminant analysis on these data. Results consistently show that generic parametric representations allow to reliably discriminate between nasals and orals. A specific issue addressed in this paper is t...

This paper proposes a new robust method for detecting step and ramp edges. In our method, an edge is defined not as a point where the in tens it,^ changes largely, but as a region boundary based on separability of image features which can be calculated by linear discriminant analysis. Based on this definition of an edge, the intensity of an edge is obtained from tlie separability, wliich depend...

This paper presents a procedure for studying industrial performance and related issues such as changes in the wage structure. This procedure combines cluster analysis and discriminant analysis as a package, and applies this package to time series data. This enables us to organize industrial data into groups with similar wage or performance histories and then to extract summary time-series showi...
