The objective of this pearl is to derive the inverse of the Burrows-Wheeler transform from its specification, using simple equational reasoning. In fact, we derive the inverse of a more general version of the transform, proposed by Schindler.

High Efficiency Video Coding (HEVC) inverse transform for residual coding uses 2-D 4x4 to 32x32 transforms with higher precision as compared to H.264/AVC’s 4x4 and 8x8 transforms resulting in an increased hardware complexity. In this paper, an energy and areaefficient VLSI architecture of an HEVC-compliant inverse transform and dequantization engine is presented. We implement a pipelining schem...

In this paper, we focus on the crowd localization task, a crucial topic of analysis. Most regression-based methods utilize convolution neural networks (CNN) to regress density map, which can not accurately locate instance in extremely dense scene, attributed two reasons: 1) map consists series blurry Gaussian blobs, 2) severe overlaps exist region map. To tackle issue, propose novel Focal Inver...

The monogenic Hua–Radon transform is defined as an orthogonal projection on holomorphic functions in the Lie sphere. Extending work of Sabadini and Sommen (J Geom Anal 29:2709–2737, 2019), we determine its reproducing kernel. Integrating this kernel over Stiefel manifold yields a linear combination zonal spherical monogenics. Using properties those monogenics, obtain inversion for transform.
