Enhancement of images with speckle noise reduction using different filters
Abstract: An Image is often corrupted by noise in its acquisition and transmission. Noise is any undesired information that contaminates an image. Speckle or Multiplicative noise, is a signal-dependent form of noise, whose magnitude is related to the value of the original pixel. This tends to reduce the image resolution and contrast. Denoising speckle is one of the most important process to inc...
متن کاملEdge Preserved Speckle Noise Reduction Using Integrated Fuzzy Filters
Echocardiographic images are inherent with speckle noise which makes visual reading and analysis quite difficult. The multiplicative speckle noise masks finer details, necessary for diagnosis of abnormalities. A novel speckle reduction technique based on integration of geometric, wiener, and fuzzy filters is proposed and analyzed in this paper. The denoising applications of fuzzy filters are st...
متن کاملthe effect of consciousness raising (c-r) on the reduction of translational errors: a case study
در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
15 صفحه اولSpeckle Noise Reduction from Medical Ultrasound Images-A comparative study
In medical image processing image denoising has become a very essential exercise all through the diagnose. Medical images are often deteriorated by noise due to a serious sources of interferences and other phenomenon that affect the measurement process in an imaging and acquisition system. Speckle noise is a random mottling of the image with bright and dark spots, which obscures fine details an...
متن کاملA Review on Speckle Noise Reduction Techniques
In medical image processing, Image denoising plays a very important role in diagnosis. Medical images are very much inconsistent. In medical imaging, Ultrasound is very popular due to its low cost, least harmful to human body, real time system and small in size. Besides itsadvantage,It suffers from a major problem i.e. speckle noise which reduces the diagnosis ability. Speckle noise is the resu...
