IRPMID: Medical XRAY Image Impulse Noise Removal using Partition Aided Median, Interpolation and DWT

The use of dental radiography techniques like XRay has increased the diagnosis efficiency, but the images contain impulse noise. Therefore, denoising is a very important factor in any subjective evaluation of the quality of images. The proposed impulse noise removal method namely ‘Impulse noise removal using Partition aided Median, Interpolation and DWT techniques’ is successfully implemented in the Dental XRAY images. The abbreviation of this method is IRPMID. The techniques such as median filter, interpolation, and Discrete Wavelet Transform (DWT) empower the proposed method with the partition based approach in denoising the salt and pepper noise. This pre-eminent method can diminish the noise range to more than 90%. The dental XRay images can gain a significant improvement in image enhancement in terms of PSNR, IEF, SSIM, etc.
