Edge preserving filters preserve the edges and its information while blurring an image. In other words they are used to smooth an image, while reducing the edge blurring effects across the edge like halos, phantom etc. They are nonlinear in nature. Examples are bilateral filter, anisotropic diffusion filter, guided filter, trilateral filter etc. Hence these family of filters are very useful in ...

Localization based on received signal strength indication (RSSI) is a low cost and low complexity technology, and it is widely applied in distance-based localization of wireless sensor networks (WSNs). Error of existed localization technologies is significant. This paper presents the N-times trilateral centroid weighted localization algorithm (NTCWLA), which can reduce the error considerably. C...

The brain tumor detection is a critical application of medical image processing. The literature survey has shown that probably the most of existing methods has ignored the indigent quality images like images which are of poor brightness or with noise. In addition, the most of the existing work on tumor detection has neglected the utilization of object-based segmentation. The overall goal of thi...

A trilateral control for LCL filter-based system is introduced by the authors with a single grid current sensor in weak conditions. The filter increases complexity when uncertain nature of comes into picture. Moreover, traditional three-loop technique requires three sensors on inverter side, voltage to sense across capacitor, and side combined sensing. novel utilising implemented current. This ...

In this note we have obtained some novel result on mixed trilateral relations involving extended Jacobi polynomials by group theoretic method which inturn yields the corresponding results involving Hermite, Laguerre and Jacobi polynomials.

The performance of local stereo matching algorithm highly depends on the support window selected, in which the cost are aggregated. A variety of cost aggregation approaches (proposed before 2008) were comprehensively analyzed in [7] and these approaches attempt to seek an optimal support window for each pixel by changing the window size, shape and center offset. The ideal optimal window should ...

Is there a widespread loss of faith in the core institutions of representative democracy? Based on a comparison of 17 trilateral democracies this study examines institutional confidence from the early 1980s to the early 1990s then considers explanations based on the social psychology of trusting personalities, cultural accounts based on life experiences, and theories of institutional performanc...
