The authors propose an orthogonal polynomial based color texture model for color texture segmentation. The proposed model is based on a complete set of difference operators which are easily configurable from a set of orthogonal polynomials. The operators are employed to represent a color image region as a linear combination of the operator's responses towards texture and noise. A simple statistical design of experiments paradigm is used for separating out the responses towards color texture from the responses towards noise. A local descriptor for color texture called cpronum is computed by encoding only the significant responses towards texture. Finally a global descriptor for color texture called cprospectrum is obtained by measuring the frequency of occurrences of the cpronums in the color image. The usage of the proposed color texture representation scheme is highlighted in unsupervised color texture segmentation.

The paper deals with comprehensive treatment of the fault tolerant characteristics of a class of nonredundant multistage interconnection network. The observations and results presented are around omega networks, as a representative member of the class of topologically equivalent nonredundant multistage interconnection network. As fault model, the paper considers that the multiple switching element fault may be in the same stage or in different stages. Several relations and expressions on different parameters and size of the network are derived to estimate the behaviour of the network of different spread towards variety of fault distribution.< >

A scheme for generating plane curves which interpolates given data is described. A curve is obtained by patching together rational cubics and straight-line segments which, in general, is C/sup 1/ continuous. It is a local scheme which controls the shape of the curve and preserves the shape of the data by being local convexity-preserving. A particular scheme is suggested which selects the tangent vectors required at each interpolation point for generating a curve. An algorithm is presented which constructs a curve by interpolating the given data points. This scheme provides a visually pleasant display of the curve's presentation. An extra feature of this curve scheme is that it allows subsequent interactive alteration of the shape of the default curve by changing the shape control parameters and the shape-preserving parameters associated with each curve segment. Thus, this feature is useful for further enhancing the user satisfaction, if desired.
