Image Retrieval Systems Essay

802 words - 4 pages

In today’s revolution oriented environment, multimedia contents play a vital role in a wide range of applications, products and services. The high usage of these contents demand efficient searching and indexing for users. This demand has drawn substantial research attention towards image retrieval systems in the last few decades. Many great methods have been proposed, which offer numerous advantages like the following.
(i) These techniques are fully automatic and avoid the manual errors of text-based systems.
(ii) These techniques avoid complex tasks like annotation and also increase the accuracy of retrieval.
(iii) These techniques also reduce the amount of garbage, that is, irrelevant ...view middle of the document...

(i) Specify a visual query (example image)
(ii) Retrieve images similar to example image from the database
The present research work proposes Content Based Image Retrieval methodology based on the effective, synergistic integration of several schemes
(i) that perform preprocessing to improve the quality of retrieval
(ii) that efficiently extracts features that best describe the contents of both the query image and the database images
(iii) that improves the searching process to retrieve images from the database that are similar to the query image .
Advancements in hardware and software technology are motivating both users and researchers to search for techniques that challenge and improve the available industrial standards for retrieving images from huge archives. This can be performed either by developing new competitive methodologies or by enriching the operations of existing methodologies as several applications require reliable models, that are efficient both in the manner of finding similar images and reducing time complexity.
The solutions provided in this research work are more compatible for retrieving images from natural and photographic image databases and use an amalgamation of image processing and machine learning algorithms to perform retrieval in a fast manner while improving both the fraction of retrieved images that are relevant to the find and fraction of the images that are relevant to the query image that are successfully retrieved.
The methodology of the proposed research work is shown in Figure 3.1 and the...

Stage Theory: Model Of Memory Essay

1124 words - 4 pages information is stored in short term memory and long term memory, the sensory store stores the information initially. The incoming information was retaining by sensory memory half a second (Goldstein, 2005). In sensory memory, information enters the human information processing system through a variety of channels connected with the different senses. A variety of sources of information are available in the environment such as light, sound, image, hot, but

Overall discussion on what it does and how the memory stores info

1250 words - 5 pages on the visual and auditory systems, although there are most likely sensory registers for all our sense. A sensory memory exists for each sensory channel: iconic for visual, echoic for hearing stimuli and hapitc for touch. It's hard to determine how much information sensory memory can hold, because the information is always fading as scientists try to measure it.George Sperling first studied iconic memory. He showed subjects sets of letters and

Technoloy in Warehouse Management

2712 words - 11 pages Retrieval Systems (AS/RS) AS/RS technology can be broken into two broad categories. These two categories are pallet handling (unit load) systems and tote handling (mini-load) systems. The world's most advanced logistics operations are characterized by automated, direct put-away to storage systems [6]. These automated systems rely on the Warehouse Management System in order to operate well. When a shipment arrives, either a conveyor is put inside of

Content-Based Image Retrieval (CBIR)

1506 words - 7 pages the case that two human users assign different descriptions for the same image, adding to the complexity of the problem. I first got interested in this topic when I first heard of content-based image retrieval (CBIR) about a year ago. A year ago, CBIR systems were still developing and maturing. Most results returned by these systems when presented with an image query back then were images that were almost identical to the query. Today, systems

Steps should also be taken to make a backup copy of the database file and save it so that eventuality can be avoided such as fire and earthquakes that can destroy the system. Information retrieval systems:  information process begins when a user enters a query into the system.  "text back" can be considered as part of the concept of "information management" is the greater.  There is a large overlap  "text again", "image" to get

Heterogeneous Parallel Ensemble Classifiers for Face Detection

1254 words - 5 pages features such as glasses, moustaches and beards further complicates the process of face detection. Face detection acts as a very first and an important step in applications such as face recognition, human computer interface, automatic surveillance and content-based image retrieval. In this paper, we proposed a face detection technique based on ensemble-classifiers, which employs multiple heterogeneous classifiers in parallel fashion. The classifiers

Comparison between the Effect of Laplacian and High Boost Filters on Spatial Domain Watermarking

1716 words - 7 pages the Discrete Cosine Transform (DCT) [7], [8] and the Discrete Wavelet Transform (DWT) [9], [10] typically bring higher image imperceptibility and more robustness to image processing operations. In order to increase the robustness of the Watermarking algorithms, there are two main methods: embedding watermark in more robust places, increase power of watermark retrieval algorithms. In the first methods, there are an attempt to use human visual
