Complexity adaptation in H.264/AVC video coder for static cameras [PDF]
H.264/AVC uses variable block size motion estimation (VBSME) to improve coding gain. However, its complexity is significant and fixed regardless of the required quality or of the scene characteristics. In this paper, we propose an adaptive complexity

Matrix Factorization and Some Fast Discrete Transforms
In this paper, three discrete transforms related to vector spaces over finite fields are studied. For our purposes, and according to the properties of the finite fields, the most suitable transforms are as follows: for binary fields, this is the Walsh ...

Remarks on numerical approximation of Volterra integral equations by Walsh–Hadamard transform
Walsh functions form a piecewise-constant orthonormal basis that is particularly well-suited for digital computation and signal approximation. Nevertheless, the direct evaluation of Walsh transforms for discrete functions becomes computationally ...

Super sub-Nyquist single-pixel imaging by means of cake-cutting Hadamard basis sort
Single-pixel imaging via compressed sensing can reconstruct high-quality images from a few linear random measurements of an object/scene known a priori to be sparse or compressive, by using a point/bucket detector without spatial resolution. Nevertheless,
