Abstract
In complementary Deoxyribonucleic Acid (cDNA) Microarray image noises usually occur during the accusation or while transmission. It is necessary to remove the noise to provide further processing techniques like edge detection, segmentation, etc. In this paper we gives comparative analysis to remove salt and pepper noise and speckle noise using different filtering techniques like standard median filter, switched median filter and vector median filter. The Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR) values are calculated for different density of salt and pepper noise and speckle noise. To find the better noise removal technique the comparison is done based on high PSNR value for different filtering techniques. The MATLAB based simulation is done to calculating the MSE and PSNR values.
