Image enhancement, especially color image enhancement is a critical area in image processing research. The wavelet analysis is widely used in signal processing and image processing. By using wavelet transform, wavelet inverse transform and an enhancement processing between the two transforms, we propose a color image enhancement method in HSV color space. More specifically, Wavelet transform is applied to the luminance component. The coefficients for the approximation components are enhanced by a gray-level image contrast enhancement technique, and then using the enhanced coefficients, the inverse Wavelet transform is performed. To the saturation component, the histogram equalization is applied. Promising results are obtained by applying the proposed method to some color images. The experimental result showed that the enhancement method can improve the performance of color images. |
