The Practice System of Physics and Electronics Courses in Higher Vocational Colleges Based on Fractional Differential Equations

Abstract This paper proposes a denoising algorithm for physical, electronic images based on fractional differential equations. The effectively combines calculus theory and gradient descent flow. At the same time, we introduce time factor into improved model spatial partial equation. We take advantage of unique amplitude-frequency characteristic operation to preserve texture details with little grayscale change in smooth area image. realizes simultaneous direction spaceplane. experimental results show that fractional-order equation method has more advantages than integer-order reducing staircase effect.
