Tri-modal technique for medical images enhancement

<span>Owing to methods of acquisition, medical images often require enhancement for them serve the intended purpose computer-aided diagnosis. Most image techniques are application specific, leading introduction different images. In addition, execution time most previous is longer than necessary. Hence, there a need method that produces fast and satisfactory results when deployed several This paper proposes tri-modal technique, involving hybrid combination unsharp masking, logarithmic transformation, histogram equalization approaches, enhancement. Three classes images: X-ray, magnetic resonance, computer tomographic used evaluations proposed method, where absolute mean brightness error, peak signal-to-noise ratio, entropy utilized as performance metrics. Both qualitative quantitative reveal performed better four in literature three evaluation. Also, technique compares well with those mono-mode methods. Thus, enhanced from inputs.</span>
