Bilateral filter is one method of image quality improvement that is nonlinear and adaptive.Bilateral filters combine geometric proximity and colour intensity similarity in mathematical calculations.This method has advantages in improving image quality compared to previous methods.Bilateral filters are used with 3 spatial coefficients and 3 photometric coefficients to process underwater images.The parametersisat used are PSNR and MSE.The results of image processing with bilateral filters are compared with the results of several studies using the trilateral filter.The results show that some studies produce low PSNR values for trilateral and high PSNR values for bilateral filters.From the calculation of Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) results showed that the value of σs = 0.5 and the value σR = 0.05 is the best coefficient obtained in the filtering process using a bilateral filter.
