Combining attention mechanism and Retinex model to enhance low-light images

Three filters for the enhancement of the images acquired from fluorescence microscope and weak-light-sources and the image compression

“…Another important approach for the image enhancement is employing Retinex theory [ [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] ]. The Retinex theory was first proposed by Land and Mccann to simulate the perception of light and color in the human visual system, where the human visual system can restore reflectance and illumination from an image [ [11] , [12] , [13] ].…”

“…This would remove the noise caused during imaging. Y. Wang et al combined attention mechanism and the Retinex theory in order to obtain the enhancement of the low-light images [ 19 ]. They developed an attention map in order to evaluate the degree of the image and guide enhancement in a region-adaptive manner.…”
