Impedance matched absorptive thermal blocking filters [PDF]
Review of Scientific Instruments, 2014 We have designed, fabricated, and characterized absorptive thermal blocking filters for cryogenic microwave applications. The transmission line filter's input characteristic impedance is designed to match 50 Ω and its response has been validated from 0 to 50 GHz.

Block Matching for Object Tracking [PDF]
, 2003 Models which describe road traffic patterns can be helpful in detection and/or prevention of uncommon and dangerous situations. Such models can be built by the use of motion detection algorithms applied to video data. Block matching is a standard technique for encoding motion in video compression algorithms.

Block-SCL: Blocking Matters for Supervised Contrastive Learning in Product Matching [PDF]
arXiv, 2022 Product matching is a fundamental step for the global understanding of consumer behavior in e-commerce. In practice, product matching refers to the task of deciding if two product offers from different data sources (e.g. retailers) represent the same product. Standard pipelines use a previous stage called blocking, where for a given product offer a set

Two-Dimensional Orthonormal Tree-Structured Haar Transform for Fast Block Matching
Journal of Imaging, 2018 The goal of block matching (BM) is to locate small patches of an image that are similar to a given patch or template. This can be done either in the spatial domain or, more efficiently, in a transform domain.

Implementation of Stereo Vision Semi-Global Block Matching Methods for Distance Measurement
Indonesian Journal of Electrical Engineering and Computer Science, 2018 Stereo vision has become an attractive topic research in the last decades. Many implementations such as the autonomous car, 3D movie, 3D object generation, are produced using this technique.

Block matching in rotated images
Electronics Letters, 2005 A rotationally invariant block-matching algorithm for matching point features in rotated images is presented. The algorithm matches the detected point features by extracting a small image area (block) centred on each point in the first image and searching for a highly similar block in the second image.

Real-Time Stereo Vision System: A Multi-Block Matching on GPU
IEEE Access, 2018 Real-time stereo vision is attractive in many areas such as outdoor mapping and navigation. As a popular accelerator in the image processing field, GPU is widely used for the studies of the stereo vision algorithms.

A sharp recovery condition for block sparse signals by block orthogonal multi-matching pursuit [PDF]
, 2016 We consider the block orthogonal multi-matching pursuit (BOMMP) algorithm for the recovery of block sparse signals. A sharp bound is obtained for the exact reconstruction of block $K$-sparse signals via the BOMMP algorithm in the noiseless case, based on the block restricted isometry constant (block-RIC).

IEEE Access, 2020 The traditional human behavior recognition algorithm is easy to ignore the spatial constraint problem of feature blocks, which leads to poor recognition effect and low correct rate. Therefore, we proposed a human motion target recognition algorithm based

Fermion-Scalar Conformal Blocks [PDF]
JHEP 1604 (2016) 074, 2015 We compute the conformal blocks associated with scalar-scalar-fermion-fermion 4-point functions in 3D CFTs. Together with the known scalar conformal blocks, our result completes the task of determining the so-called `seed blocks' in three dimensions.
