-Edge detection has fundamental importance in image analysis. Classical edge detectors work only for specific image size and fail to operate on images with strong noise. Multiwavelets can achieve and maintain detail information of image well even in noisy environment. The steps involved in canny edge detector are performed in transformed domain (using DMWT) for synthetic image. Finally the perf...

This contribution presents a simple, attractive, and exible formulation for the weighted total least squares (WTLS) problem. It is simple because it is based on the well-known standard least squares theory; it is attractive because it allows one to directly use the existing body of knowledge of the least squares theory; and it is exible because it can be used to a broad eld of applications in t...

Multiwavelet transform can be implemented by treestructured matrix lter bank, which operates on vector sequence input instead of scalar ones. Therefore, unlike in scalar wavelet system, preprocessing is usually required to extract vector sequence input from the input signal for better performance. A 2-D approximation-based preprocessing scheme for GHM (Geronimo, Hardin and Massopust) discrete m...

Multiattribute decision-making (MADM) approach is an effective method for handling ambiguous information in a practical situation. The process of the MADM technique has drawn lot interest from various academic and selection processes extensive analysis. aggregation operators (AOs) are best mathematical tools received attention researchers. This article explored theory intuitionistic fuzzy IF se...

Based on the equivalent factor table of terrestrial ESV in China 2010, this paper proposes a regionalized and interannual correction method. Taking southern Guangzhou as study area, which is located geometric center Guangdong–Hong Kong–Macao Greater Bay Area (GHM GBA), evaluated ecosystem service value (ESEV) (ESV) their changes 2004, 2010 2016 carried out grid processing, trend analysis global...

Although piezocomposite (PC) materials have increasingly attracted researchers, there is still a need to properly and easily derive their properties. We develop generalized homogenization model (GHM) that accounts for Smith Cha approaches evaluate the equivalent characteristics of piezocomposites. This method could be applied all connectivities patterns, but restricted herein 2-2 1-3 piezocompo...

Assuming that a formal specification is available, one can formally study the validation of a software with respect to its specification. While proof theories are widely investigated, testing theories have not been extensively studied. The idea of deriving test data sets from a specification can be found in [Rig 85], [Sou 88], but there are few other published works. The work reported in this p...

Orthogonal wavelet bases have been developed using multiple mother wavelet functions. Applying the discrete multiwavelet transform requires the input data to be preprocessed to obtain a more economical decomposition. Four characteristics of a preprocessing method are presented: length, degree, orthogonality and frequency response. A minimal preelter is deened to have length one and highest atta...
