Vários métodos de aprimoramento de contraste, como equalização de histograma (HE) e aprimoramento de contraste local (LCE), foram desenvolvidos para aumentar a visibilidade e os detalhes de uma imagem degradada. Propomos um método de aprimoramento de contraste de imagem baseado no ajuste global e local dos níveis de cinza, combinando métodos HE com LCE. Para a combinação ideal de ambos, introduzimos uma entropia discreta. A avaliação dos nossos resultados experimentais mostra que o método proposto supera os métodos HE e LCE.

Abstract: Various contrast enhancement methods such as histogram equalization (HE) and local contrast enhancement (LCE) have been developed to increase the visibility and details of a degraded image. We propose an image contrast enhancement method based on the global and local adjustment of gray levels by combining HE with LCE methods. For the optimal combination of both, we introduce a discrete entropy. Evaluation of our experimental results shows that the proposed method outperforms both the HE and LCE methods.
