Abstract
A method for enhancing illumination intensity of an image according to an embodiment of the present disclosure may include receiving an image, determining a filter application scheme by using a neural network model trained to enhance the illumination intensity of the image, and outputting an image having enhanced illumination intensity by applying, to the image, the determined filter application scheme. The neural network model trained using machine learning includes a first group of layers for extracting feature information of the image, a second group of layers for determining a type of filter based on the extracted feature information, and a third group of layers for determining the optimal parameter for the filter based on the extracted feature information. The neural network model may be provided through an external server in an IoT environment using a 5G network.
