Least-squares image resizing using finite differences
We present an optimal spline-based algorithm for the enlargement or reduction of digital images with arbitrary (noninteger) scaling factors. This projection-based approach can be realized thanks to a new finite difference method that allows the computation of inner products with analysis functions that are B-splines of any degree n. A noteworthy property of the algorithm is that the computation...

متن کاملSketching Image Morphing Using Moving Least Squares
Image morphing has received much attention in recent years. It has proven to be a powerful tool for visual effects in film and television, depicting the fluid transformation of one digital image into another. In this paper, we present a novel approach for image morphing based on moving least squares. A sketching interface is proposed for quickly and easily specifying the feature correspondences...
متن کاملLeast-Squares Finite Element Methods
Least-squares finite element methods are an attractive class of methods for the numerical solution of partial differential equations. They are motivated by the desire to recover, in general settings, the advantageous features of Rayleigh–Ritz methods such as the avoidance of discrete compatibility conditions and the production of symmetric and positive definite discrete systems. The methods are...
متن کاملDepth Image Enhancement using 1D Least Median of Squares
We propose a new method to enhance the depth images from RGB-D sensors, such as Kinects, by filling the missing/invalid values which are reported by those sensors at certain pixels. We introduce a robust 1D least median of squares (1D LMedS) approach to accurately estimate the depth values of those invalid pixels. We use this approach for efficient traversal of each pixel’s depth values over a ...
