The development of Internet causes an eruptive expansion of digital images, and also gives people more ways to get those images. Because the dissemination of video and image data in digital form has grown, Content Based Image Retrieval (CBIR) has become an eminent research topic. The importance of an effective technique in searching and retrieving images from the huge collection cannot be overemphasized. Therefore an important problem that needs to be addressed is fast retrieval of images from large databases. To perceive images that are perceptually similar to a query image, image retrieval systems attempt to search through a database. Content-based image retrieval utilizes representations of features that are automatically extracted from the images themselves. 

Video Retrieval (VR) has been increasingly accustomed describe the method of retrieving desired videos from an oversized assortment on the premise of options that are extracted from the videos. The extracted options are accustomed index, classify and retrieve desired and relevant videos whereas filtering out unwanted ones. Videos are often pictured by their audio, texts, faces and objects in their frames. An individual video possesses distinctive motion options, color histograms, motion histograms, text options, audio options, features extracted from faces and objects existing in its frames. Videos containing helpful info and occupying significant house within the databases are under-utilized unless VR systems capable of retrieving desired videos by sharply choosing relevant whereas filtering out unwanted videos exist. Results have shown performance improvement (higher precision and recall values) once options appropriate to particular kinds of videos are used with wisdom. Various combinations of those options also can be accustomed reach desired performance. During this paper a fancy and wide space of VR and VR systems has been bestowed in a very comprehensive and easy approach. Processes at completely different stages in VR systems are represented in a very systematic approach. Types of options, their mixtures and their utilization ways, techniques and algorithms are shown. Numerous querying methods, a number of the options get similarity like Kullback-Leibler distance method and relevancy Feedback technique are mentione dlike
