The disparate histories of binocular vision and binaural hearing [PDF]

Journal of the History of the Neurosciences, 2017
Vision and hearing are dependent on disparities of spatial patterns received by two eyes and on time and intensity differences to two ears. However, the experiences of a single world have masked attention to these disparities. While eyes and ears are paired, there has not been parity in the attention directed to their functioning.

A Stereo Disparity Map Refinement Method Without Training Based on Monocular Segmentation and Surface Normal

Remote Sensing
Stereo disparity estimation is an essential component in computer vision and photogrammetry with many applications. However, there is a lack of real-world large datasets and large-scale models in the domain.

RECOGNIZING TAMIL PALM-LEAF MANUSCRIPT CHARACTERS USING HYBRIDIZED HUMAN PERCEPTION BASED FEATURES

ICTACT Journal on Image and Video Processing, 2021
The paper presents a new Convolutional Neural Network (CNN) architecture, called stacked stereo CNN, for computing disparity map from stereo images. In stacked stereo CNN, left and right image patches are stacked back-to-back and fed to a single tower ...

Dynamics of absolute and relative disparity processing in human visual cortex

NeuroImage, 2022
Cortical processing of binocular disparity is believed to begin in V1 where cells are sensitive to absolute disparity, followed by the extraction of relative disparity in higher visual areas.

Sex Representation in US Stroke Clinical Trials: A Decade of Trends and Challenges

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke remains a major cause of disability and mortality in the US, with significant sex‐based disparities, and females remain underrepresented in stroke clinical trials. We aimed to examine sex representation in US‐based stroke clinical trials, identify trial characteristics associated with higher female enrollment (≥ 50%), and ...

Improving Census Transform by High-Pass with Haar Wavelet Transform and Edge Detection

Sensors, 2020
One of the common methods for measuring distance is to use a camera and image processing algorithm, such as an eye and brain. Mechanical stereo vision uses two cameras to shoot the same object and analyzes the disparity of the stereo vision.

A cybernetic multiresolution system for disparity estimation in stereo vision [PDF]

Kybernetes, 2006
PurposeThe aim is to obtain a dense and reliable disparity map from a stereoscopic pair under any luminosity condition. From the disparity map it is possible to obtain some information about the objects appearing in the scene, such as their position and their distance to the camera.Design/methodology/approachThe disparity map is obtained using a ...
