Color image enhancement using the laplacian pyramid

Abstract

We present a color image enhancement method. The proposed method enhances the brightness and contrast of an input image using the low pass and band pass images in Laplacian pyramid, respectively. For color images, our method enhances the color tone by increasing the saturation adpatively according to the intensity of an input image. The major parameters required in our method are automatically set by the human preference data, therefore, the proposed method runs fully automatically without user interaction. Moreover, due to the simplicity and efficiency of the proposed method, a real time implementation and the enhanced results of the image quality was validated through the experiments on various images and video sequences.
