Improved recognition of bacterial species using novel fractional-order orthogonal descriptors

Applied Soft Computing, 2020
Detection and distinguishing between different species of bacteria using experimental microbiology is an expensive, time-consuming, and risky process.

Local Orthogonal Moments for Local Features

IEEE Transactions on Image Processing, 2023
By introducing parameters with local information, several types of orthogonal moments have recently been developed for the extraction of local features in an image.

Fractional Charlier moments for image reconstruction and image watermarking

Signal Processing, 2020
In this paper, we propose a new set of discrete orthogonal polynomials called fractional Charlier polynomials (FrCPs). This new set will be used as a basic function to define the fractional discrete orthogonal Charlier moments (FrCMs). The proposed FrCPs

Perceptual Image Hashing Using Feature Fusion of Orthogonal Moments

IEEE transactions on multimedia
Due to the limited number of stable image feature descriptors and the simplistic concatenation approach to hash generation, existing hashing methods have not achieved a satisfactory balance between robustness and discrimination.

Fractional Order Tchebichef Moment and its Invariants

IEEE International Conference on Power Electronics, Intelligent Control and Energy Systems, 2018
Discrete orthogonal moments are computationally efficient as compared to its continuous counterpart. The Tchebichef moment shows less computation cost among moments defined in discrete coordinate system.

Off‐Grid DOA Estimation of Acoustic Vector Sensor Array Based on Look Ahead Strategy in Impulsive Noise

International Journal of Communication Systems
To address the issue of low direction‐of‐arrival (DOA) estimation accuracy for acoustic vector sensor arrays under impulsive noise and grid mismatch conditions, a look ahead orthogonal matching pursuit algorithm based on phased fractional lower‐order ...
