Adaptive Multi-Pattern Fast Block-Matching Algorithm Based on Motion Classification Techniques [PDF]
, 2007 Motion estimation is the most time-consuming subsystem in a video codec. Thus, more efficient methods of motion estimation should be investigated. Real video sequences usually exhibit a wide-range of motion content as well as different degrees of detail,

EBMBDT: Effective Block Matching Based Denoising Technique using dual tree complex wavelet transform
Machine Graphics & Vision, 2014 In processing and investigation of digital image denoising of images is hence very important. In this paper, we propose a Hybrid de-noising technique by using Dual Tree Complex Wavelet Transform (DTCWT) and Block Matching Algorithm (BMA).

Block Multipath Matching Pursuit
, 2023 In this paper, we propose a new reconstruction algorithm called Block Multipath Matching pursuit (BMMP), which is an extension of multipath matching pursuit (MMP) in block compressed sensing. Then the reconstruction condition of BMMP based on restricted isometric property (RIP) is established. In addition, we also provides a guarantee of reconstruction

Matching Pursuit With Block Incoherent Dictionaries [PDF]
IEEE Transactions on Signal Processing, 2007 Recently, there has been an intense activity in the field of sparse approximations with redundant dictionaries, largely motivated by the practical performances of algorithms such as matching pursuit (MP) and basis pursuit (BP). However, most of the theoretical results obtained so far are valid only for the restricted class of incoherent dictionaries ...

Efficient and Robust Feature Matching for High-Resolution Satellite Stereos
Remote Sensing, 2022 Feature matching between high-resolution satellite stereos plays an important role in satellite image orientation. However, images of changed regions, weak-textured regions and occluded regions may generate low-quality matches or even mismatches ...

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.
