SIFT keypoint descriptors for range image analysis [PDF]

open access: yes, 2007
This paper presents work in progress to extend the two-dimensional (2D) Scale Invariant Feature Transform (SIFT) into the 2.5 dimensional (2.5D) domain. Feature descriptors are extracted from range images of human faces and the form of these descriptors ...

Investigating Keypoint Repeatability for 3D Correspondence Estimation in Cluttered Scenes

open access: yes, 2017
© 2017 IEEE. In 3D object recognition, local feature-based recognition is known to be robust against occlusion and clutter. Local feature estimation requires feature correspondences, including feature extraction and matching.

Multi‐Temporal UAV Surveys and Modelling of Soil Erosion in the Ca l'Isard Catchment, NE Spain

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 5, September–October 2026.
ABSTRACT This study investigates seasonal sediment dynamics in highly active Mediterranean mountain badlands by integrating multi‐temporal Uncrewed Aerial Vehicle (UAV) surveys, and landscape evolution modelling (LEM) in the Ca l'Isard catchment (NE Spain).

Abstract PHASE INVARIANT KEYPOINT DETECTION

open access: yes, 2008
This paper introduces extensions to the keypoint detection paper [1]. Keypoints are generated by finding local peaks in accumulated, interpolated maps of the product of magnitudes of directional complex filter responses, as in earlier work.

Reliability, agreement and variability of a markerless computer vision algorithm for equine gait analysis under field conditions

open access: yesEquine Veterinary Journal, Volume 58, Issue 5, Page 1467-1481, September 2026.
Abstract Background Computer vision‐based algorithms offer accessible alternatives for equine gait analysis but require thorough assessment under diverse conditions. Objectives To evaluate a proprietary vision‐based algorithm's reliability in measuring vertical displacement signals (VDS) at the eye, withers and croup, alongside groundline estimation ...

Improving Artistic Design With KFDeformNet: Single-Frame Three-Dimensional Cartoon Face Recovery

open access: yesIEEE Access
We propose KFDeformNet, a novel framework for enhancing 3D cartoon face recovery from single-frame inputs. Existing methods struggle to capture the fine details and exaggerated characteristics common in artistic cartoon designs.

Involvement of the reticulospinal system in the control of locomotion

open access: yesThe Journal of Physiology, Volume 604, Issue 18, Page 7869-7889, 15 September 2026.
Abstract figure legend During human locomotion the legs appear to be co‐ordinated by a neural coupling mechanism. This is reflected by the observation that electrical stimuli (ES) applied to the right tibial nerve during the right swing result in a neural coupling response in the left gastrocnemius (GM, blue EMG signal).
