Survey on Content Based Image Retrieval Techniques

Abstract-Image retrieval is the process of surfing, examining and retrieving images from a huge database of digital images. There are various areas in which digital images are used such as-crime prevention, commerce, finger print recognition, surveillance, hospitals, engineering, architecture, fashion, graphic design, academics, historical research, and government institutions etc. Because of this widespread demand we need to enhance in retrieval precision and minimized retrieval time. The prior methods were only dependent on text based searching instead of its visual feature. Many times just one keyword is redundantly used with more than one images, therefore it leads to erroneous outcomes. Consequently, Content Based Image Retrieval (CBIR) is evolved to defeat the restriction of text based retrieval. There are various methods for image retrieval proposed in literature based on the content (color, texture or shape) of images. In this paper, we will provide in depth survey on image retrieval techniques
