【 摘 要 】

In this study, improvement of underwater images via colour re-correction was performed by designing a new method that uses colour restoration based on the integrated colour model with Rayleigh distribution (CRBICMRD). The proposed method was utilised for colour restoration in an image in the RGB model and for colour transformation in YCbCr space, where it processed the Y component. The integrated colour model with Rayleigh distribution was applied. Quantitative analyses indicated that the proposed method outperformed the multi-scale retinex algorithm with colour restoration, unsupervised colour correction method and Rayleigh stretching and averaging image planes by calculating no-reference-image quality assessments. Results indicated that CRBICMRD performed considerably better than the other methods in enhancing underwater images.
