Relative Pose Estimation for Multi-Camera Systems from Point Correspondences with Scale Ratio
ACM Multimedia, 2022The use of multi-camera systems is becoming more common in self-driving cars, micro aerial vehicles or augmented reality headsets. In order to perform 3D geometric tasks, the accuracy and efficiency of relative pose estimation algorithms are very ...

A Ratio Scale Measurement of Conformity [PDF]
Educational and Psychological Measurement, 1989 Since the seminal work on conformity, there has been a steady stream of research attempting to isolate individual and situational variables that influence its expression. Most previous studies have employed either proportions of participants showing conformity or have used Likert scales to measure changes in conformity as a function of different ...

Ratio-and-Scale-Aware YOLO for Pedestrian Detection
IEEE Transactions on Image Processing, 2020Current deep learning methods seldom consider the effects of small pedestrian ratios and considerable differences in the aspect ratio of input images, which results in low pedestrian detection performance.

Measurement, 2013
Abstract In the past, ratio scales have been a highly controversial issue between physicists and psychologists as regards the need for an empirical addition operation in order to attain them. This aspect is critical since such an operation is often unavailable in psychophysical experiments, as it is in physics, due to its intensive properties.

Ratio error (RE) estimation of the voltage transformers (VTs) plays an important role in modern power delivery systems. Existing RE estimation methods mainly focus on periodical calibration but ignore the time-varying property.

Learning to Reduce Scale Differences for Large-Scale Invariant Image Matching
IEEE transactions on circuits and systems for video technology (Print), 2023Most image matching methods perform poorly when encountering large scale changes in images. To solve this problem, we propose a Scale-Difference-Aware Image Matching method (SDAIM) that reduces image scale differences before local feature extraction, via

Communicating With Extremely Large-Scale Array/Surface: Unified Modeling and Performance Analysis
IEEE Transactions on Wireless Communications, 2021Wireless communications with extremely large-scale array (XL-array) correspond to systems whose antenna sizes are so large that conventional modeling assumptions, such as uniform plane wave (UPW) impingement, are no longer valid.

Saliency Based on Multi-scale Ratio of Dissimilarity
International Conference on Pattern Recognition, 2010Recently, many vision applications tend to utilize saliency maps derived from input images to guide them to focus on processing salient regions in images.

Edge statistics-based image scale ratio and noise strength estimation in DCT-coded images
IEEE transactions on consumer electronics, 2009This paper presents an algorithm for estimating the scale ratio of a compressed image and the strength of compression noise that is associated with a block-based compression scheme. The proposed basic idea was based on analyzing the block edge statistics

Some Models for Estimating Technical and Scale Inefficiencies in Data Envelopment Analysis
, 1984In management contexts, mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best. In this capacity, mathematical programming serves as a planning aid to management.
