First, an uncertainty-based detector identifies the pixels corrupted by impulse noise. Then, a weighted fuzzy mean filter is applied to remove the noise candidates. The experimental results show that, compared with the traditional switching filters, the CM filter makes a great improvement in image ...
Image processThis paper presents a simple median filter, which first applies the adaptive median filter and then evaluates a median value to perform an algorithm. Conventionally, most of the median filters have excellent performances only for the corrupted images with low-density impulse noise, but ...
The reconstructed pixels are written adaptively to the reconstructed image after the correction by the noise filter.The main feature of the proposed design is that it keeps the unaffected pixels untouched and thereby reducing the blurring effect in the reconstructed image. It requires only low ...
The purpose of this paper is to build up a detection model by using SVM-based fuzzy inference system for the impulse noise in an image. 针对图像上的脉冲噪声,用基于支持向量机的模糊推理方法建立噪声检测模型。 www.ceps.com.tw 2. Median filter is a nonlinear filtering technique widely used for...
This paper introduces the concept of image fusion technique for impulse noise reduction in digital images. Image fusion is the process of combining two or more images into a single image while retaining the important features of each image. Multiple image fusion is an important technique used in ...
This paper is concerned with partial differential equation (PDE)-based image denoising for random-valued impulse noise. We introduce the notion of ENI (the abbreviation for "edge pixels, noisy pixels, and interior pixels") that denotes the number of homogeneous pixels in a local neighborhood and...
Research on removing noise in medical image based on median filter method Removing salt-and-pepper noise in medical images plays a very important role for the preprocessing modules of virtual endoscope system. Traditional median ... CY Ning,SF Liu,Q Ming - IEEE International Symposium on It in...
Image noise is defined as the random variation of color information or intensity in images. It is recognized as a type of electronic noise. Impulse noise i... A Roy,S Chandra,R Rabidas - International Con...
The impulse noise is the biggest problem that is met by the researchers when handling the images. Impulse noises will reduce the quality of images and will degrade the performance of image handling process. There is various impulse noise removal approaches are introduced in the previous researches ...
We propose an effective method to resolve blurred images with impulse noise. Our method has two steps. First, an improved adaptive median filter is proposed for image denoising; And second, the problem of deblurring the denoised image is formulated as to minimize the object function which consist...
