Descripción: Today, as the creation and digitization of images and image retrieval have become easier, huge image databases have become more popular. The area of retrieve images based on the visual content of the query picture intensified recently, which demands on the quite wide methodology spectrum on the area of image processing. Content Based Image Retrieval (CBIR) has therefore evolved into necessity. Due  to  the  increased  garbage  value  it  is  very  important  to  design  a CBIR  system  to  retrieve  images  from  the  database  in  a  very  efficient  manner. In  this  paper  we  are going  to  propose  a  color  image  retrieval  method  based  on  the  primitives  of color  moments. At  the  starting  stage  the  image  is  divided  into  four  segments. Then  the color  moments  of  all  segments  are  extracted  and  clustered  into  four  classes. At  the  next  stage  we  will  consider  the  mean  moments  of  each  class  as  a  primitive of  the  image. All  the  primitives  are  used  as  features  and  each  class  mean  is  merged  into  a single  class  mean. The  distance  between  the  input  query  image  mean  with  the corresponding  database  images  are  calculated  by  using  SAD  method. The   analysis  results  proved  that  the  CBIR  using  our  new  method  has  the  better  performance  than   the  existing  method.
