NOISE REMOVAL IN COMPOUND IMAGE USING MEDIAN FILTER
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 4
Abstract
Compound image is a combination of text, picture and graphs. Noise reduction in compound image is necessary to maintain the quality of images. Noise is added into an image at the time of image acquisition (or) image capturing. After capturing, mage preprocessing is necessarily done to correct and adjust the image for further classification and segmentation. From the literature study different filtering techniques are available to reduce the noise from compound images. Normally the filters are used to improve the image quality, suppress the noise. This paper proposes median filtering technique for removing salt & pepper noise from various types of compound images. Several examples were conducted to evaluate the erformance of the median filter on noise.
