A Multiresolution Image Completion Algorithm for Compressing Digital Color Images
Algorithm 3
Pseudocode of proposed framework with PDEs inpainting algorithm based on
Laplacian operator.
(1) Obtain a noisy image as input | | (2) Smooth the noisy image using | | (3) Analyze the smoothed image by extracting edges through | | | (4) Identify the structural and textural regions based on the extracted edges. | (5) Skip the regions that are not selected as necessary information instead fill | the DC value and create a DC filled image | (6) Perform ANN Compression and Decompression using | | | where & are weights of compressor and decompressor respectively. | (7) Start the inpainting process with initial guess . | Set and the initial error | Where and is the inpainting region. | (8) While or | (a) Set | (b) Calculate using (12)–(15) | (c) For all update | , | where is the time step size & is the space grid size | (d) Compute error | (e) End the while loop |
