Enhancement of Echocardiographic Images of Rheumatic Heart Disease using Median filtering and Histogram Equalization Techniques

Rheumatic heart disease is a disease commonly occurring in the adults below 10 years, infants and mainly in pregnant ladies. In order to control the disease and for its proper treatment the images obtained through ultrasound must be tested using better values. In this approach first step is to filter the speckle noise from the image using median filtering, which limits the reading capability of the images obtained and once removed the speckle noise then image was enhanced using CLAHE, Typical HE, Local HE and Global HE methods. The experiments conducted using different image enhancement techniques on the image have resulted in better values like 7.35 Entropy using CLAHE, 28.82 PSNR using CLAHE, 15.94 AMBE using Local HE, 68.68 Contrast using Typical HE, MSE value of 84.54 using Local HE, SSIM.307 using CLAHE, PMSE 12.486 using CLAHE, SC.794 using CLAHE and ME-22.631 using CLAHE.
