Abstract

<abstract> <title> <x xml:space="preserve"> Abstract </x> </title> <p> <bold>Purpose</bold> – The purpose of this paper is to present a new multi‐image registration methodology that is able to align a set of hand‐held bracketed shots. <bold>Design/methodology/approach</bold> – The procedure is a two‐step algorithm where corresponding multi‐image points are automatically extracted from the bracketed image sequence and a least squares adjustment recovers transformation parameters. <bold>Findings</bold> – The images can be processed with high dynamic range algorithms to combine multiple low dynamic range pictures into a single mosaic with a superior radiometric quality. <bold>Originality/value</bold> – Simulated and real examples are illustrated to prove the effectiveness of the developed affine‐based procedure.</p> </abstract>
