		<abstract>This paper introduces a new image enhancement technique derived from histogram hyperbolization. The original method of histogram hyperbolization was based on a simple logarithmic modelo f the nonlinear characteristic of the human visual system. By using a different model, we derived a new method introduced here, called quadratic hyperbolization. Examples are provided demonstrating that satellite and side-scan sonar images processed with the quadratic hyperbolization technique may have greater intelligibility than when processed with the original histogram hyperbolization technique.</abstract>
