Abstract: An image processing method acquires an image, restores a saturated region in which a pixel in the image has a first reference value based on a first illuminance component of the image, enhances a dark region in which a value of a pixel in the image is less than a second reference value based on the restored saturated region and the first illuminance component, and outputs a dark region-enhanced image.

Abstract: Provided is a method and apparatus for rendering a target fluid that include defining level-set information of fluid particles configuring a modeled target fluid. The level-set information comprises a shortest distance from a surface of the target fluid to the fluid particles. The method and apparatus are include discarding internal particles of the target fluid from the modeled target fluid based on the level-set information of the fluid particles, and calculating thickness information of the target fluid, from which the internal particles are discarded, based on depth information on the fluid particles. The target fluid is rendered based on the thickness information of the target fluid.
