Example embodiments are directed to a system of image enhancement. An interface device is configured to receive as input one or more input images. The one or more input images have one or more exposure values. A processing device is configured to execute an exposure value (EV) resampling module to generate one or more resampled images having exposure values different from the one or more exposure values of the one or more input images. The resampled images have a range of exposure values. The processing device is configured to execute a filtering module to filter the resampled images, and output a set of filtered images. The processing device is configured to execute a blending module to sequentially blend the set of filtered images, and output a merged image.
