A new algorithm of enhancing the dark image based on dark object enhancement operator and principal component analysis

Abstract

Image enhancement is a very important topic in image processing and has achieved considerable success. However, dark image enhancement is still a difficult problem, needs further research. This paper introduces a new algorithm for dark image enhancement based on dark object enhancement and Principal Component Analysis. Our proposed algorithm combines an operator to enhance dark objects and Principal Component Analysis to perform image enhancement. Experimental results show that the proposed algorithm is better than some recent methods.
