Content based image retrieval (CBIR) is the task of searching digital images from a large database based on the extraction of features, such as color, texture and shape of the image. ...
The query image is considered to be distorted or incomplete image if it has some missing information, some undesirable objects, blurring, noise due to disturbance at the time of image acquisition etc. ...
Since the colored image has several kinds of objects, Fourier descriptor may be the best possible descriptor for calculating the boundaries of the objects present in the images. ...
