Abstract
Diagnostics and treatments of numerous diseases are highly dependent on the quality of captured medical images. However, noise (during both acquisition and transmission) is one oft he main factors that reduce their quality.This paper proposes an adaptive image denoising algorithm applied to enhance X-ray images.The algorithm is based on the modification oft he intersection of confidence intervals (ICI) rule,called relative intersection of confidence intervals (RICI) rule. For each image pixel apart,a 2D mask of adaptive size and shape is calculated and used in designing the 2D local polynomial approximation (LPA) filters for noise removal. One of the advantages of the proposed method is the fact that the estimation of the noise free pixel is performed in dependently for each image pixel and thus, the method is applicable for easy parallelization in order to improve its computational efficiency. The proposed method was compared to the Gaussian smoothing filters, total variation denoising and fixed size median filtering and was shown to outperform them both visually and in terms of the peak signal to-noise ratio (PSNR) by up to 7.99 dB.
