Deep Learning with Adaptive Attention for Seismic Velocity Inversion
Remote Sensing, 2022 The subsurface velocity model is crucial for high-resolution seismic imaging. Although full-waveform inversion (FWI) is a high-accuracy velocity inversion method, it inevitably suffers from challenging problems, including human interference, strong ...

Thematic relations affect similarity via commonalities [PDF]
, 2009 Thematic relations are an important source of perceived similarity. For instance, the rowing theme of boats and oars increases their perceived similarity. The mechanism of this effect, however, has not been specified previously.

AN IMPROVEMENT OF STRUCTURAL SIMILARITY INDEX FOR IMAGE QUALITY ASSESSMENT [PDF]
Journal of Computer Science, 2014 The image quality assessment has been widely used in image processing. Several researches have been developed and carried considering the Human Visual System (HVS). Under the hypothesis that human visual perception is extremely adapted to retrieve structural information from a scene, the SSIM index is the most widely used in this area, which leads to a

PSI: indexing protein structures for fast similarity search [PDF]
Bioinformatics, 2003 Abstract Motivation: We consider the problem of finding similarities in protein structure databases. Current techniques sequentially compare the given query protein to all of the proteins in the database to find similarities. Therefore, the cost of similarity queries increases linearly as the volume of the protein databases increase.

The fidelity of compressed and interpolated medical images
Technical Transactions, 2020 Due to the amount of medical image data being produced and transferred over networks, employing lossy compression has been accepted by worldwide regulatory bodies. As expected, increasing the degree of compression leads to decreasing image fidelity.

An Adaptive Index Structure for High-Dimensional Similarity Search [PDF]
, 2001 A practical method for creating a high dimensional index structure that adapts to the data distribution and scales well with the database size, is presented. Typical media descriptors are high dimensional and are not uniformly distributed in the feature space.
