On the Development of a Coupled Non-linear Telegraph-Diffusion Model for Image Restoration
Sudeb Majee, Subit K. Jain, Rajendra K. Ray +1
In this work, we propose a telegraph coupled partial differential equation (TCPDE) based model for image restoration. New framework interpolates between a couple of non-linear tele…
Well-posedness study of a non-linear hyperbolic-parabolic coupled system applied to image speckle reduction
Sudeb Majee, Rajendra K. Ray, Ananta K. Majee
In this article, we consider a non-linear hyperbolic-parabolic coupled system based on telegraph diffusion framework applied to image despeckling. A separate equation is used to ca…
A Gray Level Indicator-Based Regularized Telegraph Diffusion Equation Applied to Image Despeckling
Sudeb Majee, Rajendra K Ray, Ananta K Majee
In this work, a gray level indicator based non-linear telegraph diffusion model is presented for multiplicative noise removal problem. Most of the researchers focus only on diffusi…
Analysis and Simulation of a Coupled Diffusion based Image Denoising Model
Subit K. Jain, Sudeb Majee, Rajendra K. Ray +1
In this study, a new coupled Partial Differential Equation (CPDE) based image denoising model incorporating space-time regularization into non-linear diffusion is proposed. This pr…
A Fuzzy Edge Detector Driven Telegraph Total Variation Model For Image Despeckling
Sudeb Majee, Subit K Jain, Rajendra K Ray +1
Speckle noise suppression is a challenging and crucial pre-processing stage for higher-level image analysis. In this work, a new attempt has been made using telegraph total variati…
