An Improved Median Filter Using Decision Based Switching Filter
Images plays vital role in our daily life. Noise is one of the important limitation in digital image processing. Noise is basically the type of unwanted disturbance in the image. A lot study is made so outlying to diminish or confiscate noise from digital images. Most of the filter fails when the noise density is very high. This paper proposes improved modified decision based median filter whic...
متن کاملThreshold Auto-Tuning Metric Learning
It has been reported repeatedly that discriminative learning of distance metric boosts the pattern recognition performance. A weak point of ITML-based methods is that the distance threshold for similarity/dissimilarity constraints must be determined manually and it is sensitive to generalization performance, although the ITML-based methods enjoy an advantage that the Bregman projection framewor...
متن کاملSwitching Median Filter for Image Enhancement
In this paper, a new nonlinear f iltering technique is introduced for enhancement of images that are highly contaminated by impulse noise. The proposed filtering technique is more effective in eliminating impulse noise and preserving the image features. The f ilter replaces a corrupted pixel by the median value or by its processed neighboring pixel value. The uncorrupted pixels are left undistu...
متن کاملHardware Implementation of Real Time Window Based Switching Median Filter
Processing of a digital image by the use of computer algorithm is usually referred as digital image processing. However, some unwanted signals capture the image which is termed as noise. Thus the digital image filtering technique is frequently used to eliminate noise. Generally image filters are following up software approach in systems. But hardware implementation prefers in comparison with so...
متن کاملNoise adaptive soft-switching median filter
Existing state-of-the-art switching-based median filters are commonly found to be nonadaptive to noise density variations and prone to misclassifying pixel characteristics at high noise density interference. This reveals the critical need of having a sophisticated switching scheme and an adaptive weighted median filter. We propose a novel switching-based median filter with incorporation of fuzz...
