ABSTRACT
The field of image processing is addressed significantly by the role of CBIR. Peculiar query is the main
feature on which the image retrieval of content based problems is dependent. Relevant information is
required for the submission of sketches or drawing and similar type of features. Many algorithms are
used for the extraction of features which are related to similar nature. The process can be optimized by
the use of feedback from the retrieval step. Analysis of colour and shape can be done by the visual
contents of image. Here neural network, Relevance feedback techniques based on image retrieval are
discussed.
Keywords: - Colour, Database, Image, Query, Shape.
