This paper proposes a color image encryption algorithm based on a cloud model Fibonacci chaotic system, as well as a matrix convolution operation that can protect image content effectively and safely.The algorithm combines the cloud model with the generalized Fibonacci, creating a new complex chaotic system that realizes the dynamic random variatio
The growing demand for swordback hold d2 edible oils for food and fuel has increased interest in non- edible oils like waste cooking oils (WCOs) for biodiesel production.However, biodiesel faces challenges, such as low oxidative stability and poor cold flow properties.These fuel properties are influenced by the composition of fatty acid methyl este

Effective steel surface defect classification with low computational cost is essential for online quality inspection.The challenge of this task is large intra-class differences and unclear inter-class distances shown in various surface defects.This paper proposes a 5.7 procharger novel feature extraction method based on Legendre multi-wavelet trans
