Web3. Principle Description of HGFG Algorithm. This paper proposes an image haze removal algorithm based on histogram gradient feature guidance (HGFG), which organically combines the guiding filtering principle and dark channel prior method, and fully considers the content and characteristics of the image. WebMar 24, 2024 · The term "gradient" has several meanings in mathematics. The simplest is as a synonym for slope . The more general gradient, called simply "the" gradient in vector analysis, is a vector operator denoted and sometimes also called del or nabla. It is most often applied to a real function of three variables , and may be denoted (1)

WebJan 16, 2024 · Gradient For a real-valued function f(x, y, z) on R3, the gradient ∇ f(x, y, z) is a vector-valued function on R3, that is, its value at a point (x, y, z) is the vector ∇ f(x, y, z) = ( ∂ f ∂ x, ∂ f ∂ y, ∂ f ∂ z) = ∂ f ∂ xi + … WebMolecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero.The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. WebViscosity Formula. Viscosity is measured in terms of a ratio of shearing stress to the velocity gradient in a fluid. If a sphere is dropped into a fluid, the viscosity can be determined using the following formula: η = 2 g a 2 ( ∆ ρ) 9 v.
