Abstract:
X-ray image plays a very important role in the medical identification. To  help  the  doctors for  diagnosis  of  the disease, some Transform  for enhancing g X-ray images were proposed  in  the  past  decadesI mage   enhancement  is  considered  as  one  of  the  most important techniques  in  image  research.  . Many  images  like  medical   images,  satellite,  floating images  and  also  real  life  photographs  suffer  from  poor and  bad  contrast  and  noise. It  is  necessary  to  improve  the  contrast   and   eliminate   the  noise  to   increase   image   quality  viewing,  removing blurring  and  noise,  increasing  contrast,  and  revealing details. These are examples   of enhancement operations. The enhancement technique   differs from one field to another depending on its   objective.  The existing techniques of image   enhancement   can be classified into two categories:  Spatial Domain and Transform Domain Enhancement.  In  this  paper,  we  present  an  overview  of Image  Enhancement  Processing  Techniques  in  Transform Domain. More explicitly, we classifications processing methods based illustrative techniques of Image enhancement.  Thus  the  contribution  of  this  paper  is  to classify and review Image Enhancement Processing Techniques  as  well  as  Speckle  noise  has  been  applied  to the  image.  Also  we  applied  various  transformation  to identify which  Transform  is  efficient   in  removing particular  noises.  This  is  identified  by  comparing  the values  obtained  in   PSNR  and  MSE  values.
