Distort Definition & Meaning - Merriam-Webster

Webgradient method [13], Born iterative method [14], subspace optimization method [15], and the distorted Born iterative method (DBIM) [16, 17] are the most popular deterministic algo-rithms. Among them, DBIM is awidely used regularized iterative algorithm because of its abil-ity to reconstruct high-resolution images with a faster rate of convergence. WebThe Distorted-Born iterative method (DBIM) is often used to solve the inverse problem. In this method, Green's function is repeated each iteration, causing DBIM to converge quickly (Montero & Janniel, 2009).
