Abstract: Systems, apparatuses, and methods for implementing defogging techniques for images and video are disclosed. A defogging engine generates a defog filter result from a grayscale format version of an input image. An estimation engine generates an enhancement strength variable from a hue-saturation-value (HSV) format version of the input image. An enhancement engine receives both the defog filter result from the defogging engine and the enhancement strength variable from the estimation engine. The enhancement engine also receives the original red-green-blue (RGB) color space format version of the input image. The enhancement engine generates an enhanced version of the input image from the original RGB format version based on the defog filter result and the enhancement strength variable. The enhanced version of the input image mitigates fog, haze, mist or other environmental impediments that obscured the original input image.
