Processing an image is the method of exploring and manipulating a digitized image to recuperate the significant information of the image. Removal of corrupted data from the image is an major task in digital image processing. This paper presents a review on diverse techniques of image denoising and segmentation including 2D NHA. The 2D Non-Harmonic Analysis (2D NHA) is a high-resolution frequency estimation method that enhances noise exactness due to its side-lobe diminishing feature. The segmentation of corrupted images includes fuzziness in the selection of the region boundary. We believe that these fuzzy boundaries should be defined as edge areas.. The execution of NHA de-noising is necessary to approach the point of confinement of PSNR by enhancing the segmentation technique
