Existing dehazing methods sometimes produce bluish artefact when the transmission is wavelength‐dependent. In this Letter, a single image dehazing method in which transmissions of RGB colour channels are estimated using inter‐channel correlations is proposed. The proposed method estimates a particle size parameter in the atmosphere using the correlation between red and blue channels. The proposed method adjusts the transmissions of red and blue colour channels with respect to the reference (green) colour transmission that is obtained by the existing dehazing method. Experimental results with a number of foggy and thin hazy images show that the proposed method effectively reduces the bluish artefact.
