In order to solve the problems such as insufficient transmittance estimation and color cast of results of dehazing algorithms, an image restoration algorithm based on minimum channel interval estimation and transmittance adaptive constraint model is proposed. Firstly, bright channel of hazy image is obtained by using maximum operation of different sizes, and average value processing and frequency domain filtering are combined to get the atmospheric light estimation. Secondly, starting from the atmospheric imaging theory, minimum channel of hazy image is regarded as a constraint, then upper and lower boundaries of minimum channel of hazy image are fitted by plane model and adaptive mapping model respectively, and minimum channel of dehazed image and initial transmittance estimation are obtained. Finally, the initial transmittance can be refined by filter smoothing and adaptive boundary constraints to obtain the optimized transmittance, and according to atmospheric scattering model, restoration results are obtained. Experiments show that the restoration results of the proposed algorithm have natural colors, appropriate brightness, thorough degree of dehazing, rich detailed information and low time complexity, which effectively solves the problems of insufficient transmittance estimation and color cast.
