Distribution probability‐based self‐adaption metric learning for person re‐identification

open access: yesIET Computer Vision, 2022
Person re‐identification addresses the problem of pedestrian image matching in a non‐overlapped surveillance network. Traditional metric learning methods try to learn a fixed pedestrian images matching metric model.

Random projection tree similarity metric for SpectralNet

open access: yesArray, 2023
SpectralNet is a graph clustering method that uses neural network to find an embedding that separates the data. So far it was only used with k-nn graphs, which are usually constructed using a distance metric (e.g., Euclidean distance).

On the Stability and Acceleration of Projection Algorithms

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The focus of this paper is the presentation of a new type of mapping called projection Jungck zn- Suzuki generalized and also defining new algorithms of various types (one-step and two-step algorithms) (projection Jungck-normal N algorithm, projection ...

The generalized projection methods in countably normed spaces

open access: yesJournal of Inequalities and Applications, 2021
Let E be a Banach space with dual space E ∗ $E^{*}$ , and let K be a nonempty, closed, and convex subset of E. We generalize the concept of generalized projection operator “ Π K : E → K $\Pi _{K}: E \rightarrow K$ ” from uniformly convex uniformly smooth

An approximation of solutions of variational inequalities

open access: yesFixed Point Theory and Applications, 2005
We use a Mann-type iteration scheme and the metric projection operator (the nearest-point projection operator) to approximate the solutions of variational inequalities in uniformly convex and uniformly smooth Banach spaces.

Generalizing the Kantorovich Metric to Projection-Valued Measures [PDF]

open access: yes, 2016
Given a compact metric space $X$, the collection of Borel probability measures on $X$ can be made into a compact metric space via the Kantorovich metric. We partially generalize this well known result to projection-valued measures. In particular, given a

Lattice-like operations and isotone projection sets [PDF]

open access: yes, 2013
By using some lattice-like operations which constitute extensions of ones introduced by M. S. Gowda, R. Sznajder and J. Tao for self-dual cones, a new perspective is gained on the subject of isotonicity of the metric projection onto the closed convex ...

Continuous metric projections [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
An example is given of a reflexive, rotund Banach space whose dual space is not Frechet differentiable such that every metric projection onto closed subspaces is norm continuous. This example shows that several published conjectures on necessary and sufficient conditions for a reflexive, rotund Banach space to have norm continuous metric projections ...

Age Sensitivity of Face Recognition Algorithms [PDF]

open access: yes, 2013
This paper investigates the performance degradation of facial recognition systems due to the influence of age. A comparative analysis of verification performance is conducted for four subspace projection techniques combined with four different distance ...

Layered Projection-Based Quality Assessment of 3D Point Clouds

open access: yesIEEE Access, 2021
Point clouds are subject to various distortions during point cloud processing missions, any of which may lead to quality degradation. Consequently, predicting point cloud quality has attracted a lot of attention. In this paper, a layered projection-based
