基于同态滤波的水下图像增强与色彩校正模型
Underwater image enhancement and color correction model based on homomorphic filter
摘要
Abstract
The degree of light attenuation varies corresponds to the different wavelengths in water substance.The clarity and color constancy for underwater image are restricted due to this property.An underwater image enhancement and color correction model based on homomorphic filter is proposed to deal with the luminance and color distortion for underwater image.Firstly,the underwater imaging model is established by Beer-Lambert law.Secondly,homomorphic filter is employed to estimate the underwater image without light attenuation.Finally,an underwater image color correction model is derived from the series expansion of underwater imaging model to keep color constant.Experiments compare the subjective visual effect and objective assessment index of underwater image.Experimental results show that the proposed model is effective to enhance the clarity and color constant for underwater image.The proposed model produces a detailed and real colorful underwater image after correction.关键词
