Comparative Study and Analysis of Advanced Denoising Techniques for Speckle Noise Reduction in Ultrasound Images

Unexpected changes in the brightness and color values in the images causes introduction of distortion or noise in the image and frames of the video stream. Such random unexpected variation in the brightness and color values doesn’t carry any intelligence or information in the image, in fact it degrades the quality of the image. To minimize the effect of such meaningless information, denoising frameworks are designed. In this research paper we have studied various denoising frameworks for speckle noise reduction and proposed a de-speckling algorithm. The performance evaluation is carried out with evaluation parameters such as PSNR and MSSIM.
