TL;DR: An interpolation algorithm for conversion from the interlaced to the progressive scanning format using a fuzzy rule-based edge-restoration interpolation part using the different types of edge, peak, and monotonic slope patterns.
Abstract: This paper proposes an interpolation algorithm for conversion from the interlaced to the progressive scanning format. The proposed algorithm consists of two parts: an edge direction detection part and a fuzzy rule-based edge-restoration interpolation part. The different types of edge, peak, and monotonic slope patterns are considered in a spatial domain interpolation strategy. Edges with a certain vertical component look preserved in the interpolation using a fuzzy rule-based algorithm. The vertical resolution in the interpolated image is subjectively concealed by introducing vertical gradients in the interpolation. Computer simulations verify the effective performance of this image processing technology.

TL;DR: Based on the prior knowledge of the model of Fresnel zone plate with circular diffraction gratings, the pixel density is increased by the bicubic interpolation (BIP) method inside the hologram to enhance the low-frequency terms of the object as mentioned in this paper.

TL;DR: In this article, the Ritz method was used to solve the variational problem for plate bending by bicubic fundamental splines, which is a piecewise polynomial method, adaptable to practical numerical computation and can be an alternative for the well-known Finite Element Method.
Abstract: This paper deals with solving the two-dimensional variational problem for plate bending by the Ritz method using bicubic fundamental splines. It is a piecewise polynomial method, very adaptable to practical numerical computation, and can be an alternative for the well-known Finite Element Method1.

TL;DR: The rational cubic function is extended to rational bicubic partially blended function (Coons Patches) and simple constraints are derived on free parameters in the description of rational bimodal partially blended patches to visualize the monotone data in the view ofmonotone surfaces.
