However, due to some technical difficulties during the time of acquisition and digital storage of mammogram images, impulse noise may be present. Therefore, detection and removals of impulse noise from the mammogram images are very essential for early detection and further diagnosis of breast cancer. In this paper, a novel adaptive trimmed median filter (ATMF) is proposed for impulse noise (salt &amp; pepper (SNP)) detection and removal with an application to mammogram image denoising. Automatic switching mechanism for updating the Window of Interest (WoI) size from ([Formula: see text]) to ([Formula: see text]) or ([Formula: see text]) is performed. The proposed method is applied on publicly available mammogram images corrupted with varying SNP noise densities in the range 5%\u201390%. The performance of the proposed method is measured by various quantitative indices like peak signal to noise ratio (PSNR), mean square error (MSE), image enhancement factor (IEF) and structural similarity index measure (SSIM). The comparative analysis of the proposed method is done with respect to other state-of-the-art noise removal methods viz., standard median filter (SMF), decision based median filter (DMF), decision based unsymmetric trimmed median filter (DUTMF), modified decision based unsymmetric trimmed median filter (MDUTMF) and decision based unsymmetric trimmed winsorized mean filter (DUTWMF). The superiority of the proposed method over other compared methods is well evident from the experimental results in terms of the quantitative indices (viz., PSNR, IEF and SSIM) and also from the visual quality of the denoised images. Paired t-test confirms the statistical significance of the higher PSNR values achieved by the proposed method as compared to the other counterpart techniques. The proposed method turned out to be very effective in denoising both high and low density noises present in (mammogram) images. <\/jats:p>","DOI":"10.1142\/s0219467820500321","type":"journal-article","created":{"date-parts":[[2020,10,17]],"date-time":"2020-10-17T15:41:00Z","timestamp":1602949260000},"page":"2050032","source":"Crossref","is-referenced-by-count":7,"title":["Adaptive Trimmed Median Filter for Impulse Noise Detection and Removal with an Application to Mammogram Images"],"prefix":"10.1142","volume":"20","author":[{"given":"Rubul Kumar","family":"Bania","sequence":"first","affiliation":[{"name":"Department of Computer Application, North-Eastern Hill University, Tura Campus, Tura 794002, Meghalaya, India"}]},{"given":"Anindya","family":"Halder","sequence":"additional","affiliation":[{"name":"Department of Computer Application, North-Eastern Hill University, Tura Campus, Tura 794002, Meghalaya, India"}]}],"member":"219","published-online":{"date-parts":[[2020,10,16]]},"reference":[{"issue":"11","key":"S0219467820500321BIB001","doi-asserted-by":"crossref","first-page":"1317","DOI":"10.1001\/jama.292.11.1317","volume":"192","author":"Warner E.","year":"2004","journal-title":"Journal of American Medical Associations"},{"issue":"4","key":"S0219467820500321BIB002","doi-asserted-by":"crossref","first-page":"646","DOI":"10.1016\/j.patcog.2005.07.006","volume":"39","author":"Cheng D.
