Refining image retrieval based on context-driven methods

Refining image retrieval based on context-driven methods

Proceedings of the 1999 7th conference of the storage and retrieval for image and video databases Vii

作者： Hong, Dezhong Wu, Jian-Kang Singh, Sumeet Sohan RWCP Information-Base Functions KRDL Lab Singapore

A prototype of the content-based image retrieval system is implemented based on the algorithms introduced in this paper. The image contents at the high levels are extracted. The fuzzy C-means classifier is employed to compute the object clusters and provide useful information for overlapped clusters. The automatic image segmentation and categorisation is achieved. To obtain the context for image retrieval, the subjective context and the objective context are modelled by means of the fuzzy sets theory. The system is able to trace the users' interactions during retrieval. The refinements of the retrieval results can be made while the users are submitting the queries telling the specific requirements.

video and image clustering using relative entropy

Video and image clustering using relative entropy

引用

Proceedings of the 1999 7th conference of the storage and retrieval for image and video databases Vii

作者： Iyengar, Giridharan Lippman, Andrew B. MIT Media Lab Cambridge MA United States

In this paper, we present an approach to clustering video sequences and images for efficient retrieval using relative entropy as our cost criterion. In addition, our experiments indicate that relative entropy is a good similarity measure for content-based retrieval. In our clustering work, we treat images and video as probability density functions over the extracted features. This leads us to formulate a general algorithm for clustering densities. In this context, it can be seen that an euclidean distance between features and the Kullback-Liebler (KL) divergence give equivalent clustering. In addition, the asymmetry of the KL divergence leads to another clustering. Our experiments indicate that this clustering is more robust to noise and distortions compared with the one resulting from euclidean norm.

28th International conference on Artificial Neural Networks (ICANN)

Recently we presented text storage and retrieval in an auto-associative memory framework using the Hopfield neural-network. This realized the ideal functionality of Hopfield network as a content-addressable information retrieval system. In this paper, we extend this result to multi-modal patterns, namely, images with text captions and show that the Hopfield network indeed can store and retrieve such multimodal patterns even in an auto-associative setting. Within this framework, we examine two central issues such as (i) performance characterization to show that the O(N) capacity of the Hopfield network for a network of size N neurons under the Pseudo-inverse learning rule is still retained in the multi-modal case, and (ii) the retrieval dynamics of the multi-modal pattern (i.e., image and caption together) under various types of queries such as image+caption, image only and caption only, in line with a typical multi-modal retrieval system where the entire multi-modal pattern is expected to be retrieved even with a partial query pattern from any of the modalities. We present results related to these two issues on a large database of 7000+ captioned-images and establish the practical scalability of both the storage capacity and the retrieval robustness of the Hopfield network for content-addressable retrieval of multi-modal patterns. We point to the potential of this work to extend to a more wider definition of multi-modality as in multi-media content, with various modalities such as video (image sequence) synchronized with sub-title text, speech, music and non-speech.

7th storage and retrieval for image and video databases conference

作者： Divakaran, A Ito, H Sun, HF Poon, T Mitsubishi Elect Informat Technol Amer Adv Televis Lab New Providence NJ 07974 USA

In this paper we present a new computationally efficient and effective technique for detection of abrupt scene changes in MPEG-4/2 compressed video sequences. We combine the de image based approach of Yeo and Liu(1) with the bit allocation change based approach of Feng, Lo and Mehrpour.(2) The bit allocation based approach has the advantage of computational simplicity since it only requires entropy decoding of the sequence. Since extraction of de images from I-Frames/Objects is simple, the de image based technique of Yeo is a good alternative for comparison of I-frames/objects. For P-frames/objects however, Yeo's algorithm requires additional computation. We find that the bit allocation change based approach is prone to false detection in comparison of intra-coded objects in MPEG-4 sequences. However, if a suspected scene/object change has been located accurately in a group of consecutive frames/objects, the bit allocation based technique quickly and accurately locates the cut point therein. This motivates us to use de image based detection between successive I-Frames/Objects to identify the sub-sequences with scene/object changes, and then use bit allocation based detection to find the cut point therein. Our technique thus has only a marginally greater complexity than the completely bit allocation based technique but has greater accuracy. It is applicable to both MPEG-2 sequences and MPEG-4 multiple-object sequences. In the MPEG-4 multiple object case, we use a weighted sum of the change in each object of the frame using the area of the object as the weight.

The large scale proliferation of multimedia data necessitates the use of sophisticated techniques for accessing the information based on the content. videoRoadMap is a new content-based video indexing system for retrieving video clips and images from multimedia databases. The system indexes the audio-visual information using spatio-temporal features and information modeling methods. The proposed system employs adaptive similarity measurements based on the contents of media objects, resulting in more accurate retrievals. Principal component analysis and second order statistical analysis are employed to determine the appropriate combination of weight values in similarity search. In addition, videoRoadMap includes a powerful multi-faceted querying mechanism which allows queries to be formulated and presented in a variety of modes, including query by example (image and/or video), query by sketch, and query by object motion trajectory.

Proceedings of the 1999 7th conference of the storage and retrieval for image and video databases Vii

The Web-based Medical Information retrieval System (WebMIRS) allows Internet access to databases containing 17,000 digitized x-ray spine images and associated text data from National Health and Nutrition Examinations Surveys (NHANES). WebMIRS allows SQL query of the text, and viewing of the returned text records and images using a standard browser. We are now working (1) to determine utility of data directly derived from the images in our databases and (2) to investigate the feasibility of computer-assisted or automated indexing of the images to support image retrieval of images of interest to biomedical researchers in the field of osteoarthritis. To build an initial database based on image data, we are manually segmenting a subset of the vertebrae, using techniques from vertebral morphometry. From this, we will derive and add to the database vertebral features. This image-derived data will enhance the user's data access capability by enabling the creation of combined SQL/image-content queries.

The purpose of the work is to discuss the fundamental issues and solutions in managing compressed and uncompressed multimedia data, especially voluminous continuous mediatypes (video, audio) and text in a memory hierarchy with four levels (main memory, magnetic disk, (optical or magnetic) on-line/near-line low-speed memory, and slow off-line memory, i.e. archive). We view the multimedia data in such a database to be generated, (compressed), and stored into the memory hierarchy (at the lowest non-archiving level), and subsequently retrieved, (decompressed), and presented. If unused, the data either travels down in the memory hierarchy or it is compressed and stored at the same level. We first discuss the general prerequisites of the memory hierarchy, like program locality and decreasing storage costs and performance of each deeper level. To discuss the issues in a greater depth a schematic four level memory hierarchy model is presented. Multimedia data poses, as compared to conventional data, three new requirements for a memory hierarchy. First, continuous multimedia data (e.g. audio and especially video) have real-time requirements for the retrieval time, not present in a conventional memory hierarchy supporting e.g. a virtual memory. Second, single multimedia objects are often very large, requiring hundreds of megabytes, even gigabytes of memory. From the memory hierarchy point of view the latter fact necessitates partial storage strategies at different levels. Third, the data is so voluminous that compression becomes an interesting alternative, because of considerable savings in storage capacity and I/O and network bandwith. Based on the real time requirements of continuous multimedia data one can set boundaries for the maximum retrieval time Tr-max Further, knowing the average retrieval speed S-i of the particular memory level i for an arbitrary object X one can determine the deepest possible (i.e. slowest) level the data can be placed on. The inequality Tr(O-j)

A challenging problem to construct video databases is the organization of video information. The development of algorithms able to organize video information according to semantic content of the data is getting more and more important. This will allow algorithms such as indexing and retrieval to work more efficiently. Until now, an attempt to extract semantic information has been performed using only video information. As a video sequence is constructed from a 2-D projection of a 3-D scene, video processing has shown its limitations especially in solving problems such as object identification or object tracking, reducing the ability to extract semantic characteristics. A possibility to overcome the problem is to use additional information. The associated audio signal is then the most natural way to obtain this information. This paper will present a technique which combines video and audio information together for classification and indexing purposes. The classification will be performed on the audio signal;a general framework that uses the results of such classification will then be proposed for organizing video information.

Proceedings of the 1995 IEEE International conference on image Processing. Part 3 (of 3)

作者： Sawhney, Harpreet S. Ayer, Serge Gorkani, Monika IBM Almaden Research Cent San Jose United States

The major inhibitors of rapid access to on-line video data are costs and management of capture and storage, lack of high-speed real-time delivery and non-availability of content and context based intelligent search and indexing techniques. The solutions for capture, storage and delivery maybe on the horizon, however the lack of visual content based indexing of video and image information may still inhibit as widespread a use of this information modality as that of text or tabular data is currently. In this paper, we present techniques for compact visual representation of video data that will be useful for visual content based presentation and indexing. video data comes in torrents - almost a megabyte every 30th of a second - but also affords the exploitation of relatively smoothly changing information over time. The techniques presented exploit the motion information across video frames to represent the underlying scene in a compact visual form as it is seen across many slowly varying frames in a video. Two classes of techniques are presented: (i) dominant motion estimation based techniques which exploit a fairly common occurrence in videos that a mostly fixed background (scene) is imaged with or without independently moving objects, and (ii) simultaneous multiple motion estimation and representation of motion video using layered representations.

Proceedings of the 1999 7th conference of the storage and retrieval for image and video databases Vii

作者： Fernando, W.A.C. Canagaraja, C.N. Bull, D.R. Univ of Bristol Bristol United Kingdom

video parsing is an important step in content-based indexing techniques where the input video is decomposed into segments with uniform content. In video parsing detection of scene changes is one of the approaches widely used for extracting key frames from the video sequence. In this paper, an algorithm based on motion vectors is proposed to detect sudden scene changes and gradual scene changes (camera movements such as panning, tilting and zooming). Unlike some of the existing schemes, the proposed scheme is capable of detecting both sudden and gradual changes in uncompressed as well as compressed domain video. It is shown that the resultant motion vector can be used to identify and classify gradual changes due to camera movements. Results show that algorithm performed as well as the histogram-based schemes with uncompressed video. The performance of the algorithm was also investigated with H.263 compressed video. The detection and classification of both sudden and gradual scene changes was successfully demonstrated.
