This paper describes the noise reduction performance of a switching vector median filter with a random-valued impulse noise detector for color images. As a random-valued impulse noise detector, a minimum spanning tree (MST)-based method is employed. In the switching vector median filter, the impulse noise detector is employed before filtering, and the detection result is used to judge whether a...

In this paper, noise reduction performance of a switching vector median filter with a random-valued impulse noise detector for color images is evaluated. As a random-valued impulse noise detector, a method utilizing the minimum spanning tree (MST) is employed. In the switching vector median filter, the impulse noise detector is employed before filtering, and the detection result is used to cont...

are inherently more resistant to impulse noise than single carrier systems, impulse noise can still be a significant problem in many applications including digital television. A number of impulse noise mitigation algorithms are investigated. These use non linear processing on the digital input signals to limit the size of impulses reaching the demodulator. It is shown that when the noise at the...

Impulse noise is corrupted in the field of DIP applications of transmission and reception due to unwanted disturbance. So, the original image will corrupted at the acquiring end. The various denoising filter algorithm of impulse noise reduction in this survey were studied. So the impulse noise detection and removal technique, they have several drawbacks also discussed for various image with var...

This paper presents a review of recent algorithms for noise reduction in images. The techniques discussed here deals with the impulse, multiplicative and Gaussian noise. Image fusion technique is employed as a general model for impulse noise meanwhile the static based median filter is mentioned for the salt and pepper noise reduction. Multiplicative noise reduction techniques involve the applic...

Digital Images are an important medium to convey visual information. However, digital images are often corrupted by noise. In this paper, an efficient implementation scheme for median filter is proposed, which is used to remove impulse noise from images. So, the resultant image of the filter is the image with reduced impulse noise. Impulse noise reduction is done using the application of the me...

An algorithm of the color image noise removal algorithm is put forward based on the pixel operations. The idea of the algorithm is to read every pixel in a set order and determine whether the pixel level is consistent with the probability density function of impulse noise or not. If it is similar to noise pixel, the number of impulse noise in a certain mask is counted. If the number is less tha...

Image is a powerful medium to convey visual information. During image transmission and acquisition, the impulse noise is corrupted in the field of digital image processing applications of transmission and reception due to unwanted disturbance. The proposed cloud noise filtering algorithm and VLSI architecture is used to remove the impulse noise is better than other methods. Extensive experiment...
