Conference on storage and retrieval for image and video databases II

We describe the Photobook system, which is a set of interactive tools for browsing and searching images and image sequences. These tools differ from those used in standard image databases in that they make direct use of the image content rather than relying on annotations. Direct search on image content is made possible by use of semantics-preserving image compression, which reduces images to a small set of perceptually-significant coefficients. We describe three Photobook tools in particular: one that allows search based on grey-level appearance, one that uses 2D shape, and a third that allows search based on textural properties.

In this paper, a method of image information retrieval is presented. The method employs a new similarity measure between graph representations of images. The measure is effective for drawing images that describe logical meaning by their structure. Most of the currently available image database systems offer retrieval functions called key word retrieval, where users specify key words such as titles, attributes, and categories of themes. But it is not easy for the users to select suitable key words according to the purpose of retrieval. So recently some retrieval functions called similarity retrieval have been proposed, where users specify key images by means of examples, sketches, and icons. We are developing a drawing image database system that stores plant diagrams. The system scans, recognizes, and stores plant diagrams. Then users can refer to any parts of the diagrams according to their needs. The system is used as a help to plant observation and control. To realize similarity retrieval for logically structured drawings like plant diagrams, we introduced a graph representation of drawings, which is suitable to deal with their logical structure. Then we defined a similarity measure between them. In this paper, effectiveness of the similarity measure and applicability to plant diagrams are discussed and some experimental results are shown.

This paper describes various image database archiving solutions implemented by high volume semiconductor manufacturers. The solutions address the primary need of the manufacturing environment to have pictorial information and associated data instantly available throughout the manufacturing process. The problems explored in this paper include the interfacing of various devices that produce data, management of the large space requirements that image storage requires, and handling the mixing of different image formats such as NTSC and PAL. The discussion covers the collection and archiving of information from a variety of input devices such as analog video cameras, digital cameras, and scanning electron microscopes (SEM). The discussion also includes the problems and solutions of establishing a common format to allow one system to collect, merge, store, and recover a variety of pictorial information and data in one video medium. The solutions include a mix of analog and digital technology. Arguments are presented in favor of archiving images in their native format, analog or digital, and the advantages and disadvantages of each of the different formats.

storage and retrieval for image and video databases VI Conference

In this paper we consider the problem of similarity between video sequences. Three basic questions are raised and (partially) answered. Firstly, at what temporal duration can video sequences be compared? The frame, shot, scene and video levels are identified. Secondly, given some image or video feature, what are the requirements on its distance measure and how can it be "easily" transformed into the visual similarity desired by the inquirer? Thirdly how can video sequences be compared at different levels? A general approach based on either a set or sequence representation with variable degrees of aggregation is proposed and applied recursively over the different levels of temporal resolution. It allows the inquirer to fully control the importance of temporal ordering and duration. Promising experimental results are presented.

Organizing video shots into hierarchy structures is very important for efficient browsing and retrieval on large video databases, and many shot organizing methods have been proposed. Most algorithms are based on automatic clustering schemes, which usually fail to give satisfactory results in real applications. In this paper, we proposed a preprocessing technology for interactive shot organizing - similarity sequence. It differs from traditional shot organizing methods in that it does not classify shots, instead it only reorders the shot sequence so that similar shots appear near each other, thus provides an effective interactive shot organizing interface and leaves the classification work to the user. A measure called similarity length was introduced to evaluate the similarity between adjacent shots in shot sequence, and an improved genetic algorithm was developed to calculate the similarity sequence. Basic thoughts and implementation details are provided, also with experiment results on real videos and analysis.

In this paper we address image retrieval by similarity in multimedia databases. We discuss the generation and use of signatures computed from image content. The proposed technique is not based on image annotation, therefore it does not require human assistance. Signatures abstract the directionality of image objects. They are computed from the image Fourier transform, and the influence of computation parameters on signature effectiveness is discussed. retrieval is based on spectrum comparison between a reference image, assumed as the query, and the images in a collection. We introduce a metric for comparing the spectra and ranking the result, and approach the issue of partial query specification. Sample results on a small test collection are given.

In this paper, we study the possibility of using Θ-index for retrieval of imagebase. image retrieval is related to partition in an image space. If there exists a mapping from an image space to a feature space, the partition in the image space can be converted into a partition in the feature space. To retrieve an image, some features of the image must be identified. Feature identification can be considered as optimal assignment of some indices to images. This is equivalent to an optimal partition of image space into mutual exclusive regions, each corresponding to particular values of a set of indices. In our system, the feature extraction is implemented by a two-dimensional Θ-transformation. The time complexity for a Θ-transformation is very low. Therefore, for a certain class of images, Θ- transformation is a very efficient algorithm for image indexing.

The color hologram of an image has been widely used as a feature descriptor for the image in content-based retrieval applications. In this paper, some results from our investigation efforts into to usage are reported. We outline three typical color space quantization schemes used in our experiments and introduce the soft-decision histogramming method to eliminate the discontinuity problem in traditional color histogram population process. Then, to improve the effectiveness of color histogram based retrieval algorithms, several similarity metrics are proposed for comparing color histograms, including three special forms of the Kantorovich metric.

A hierarchical human detection system in (un)compressed domains

IEEE TRANSACTIONS ON MULTIMEDIA 2002年第2期4卷 283-300页

作者： Ozer, IB Wolf, WH Princeton Univ Dept Elect Engn Princeton NJ 08544 USA

With the rapid growth of multimedia information in forms of digital image and video libraries, there is an increasing need for intelligent database management tools with an efficient information retrieval system. For this purpose, we propose a hierarchical retrieval system where shape, color and motion characteristics of human body are captured in compressed and uncompressed domains. The proposed retrieval method provides human detection and activity recognition at different resolution levels from low complexity to low false rates and connects low level features to high level semantics by developing relational object and activity presentations. The available information of standard video compression algorithms are used in order to reduce the amount of time and storage needed for the information retrieval. The principal component analysis is used for activity recognition using MPEG motion vectors and results are presented for walking, kicking, and running to demonstrate that the classification among activities is clearly visible. For low resolution and monochrome images it is demonstrated that the structural information of human silhouettes can be captured from AC-DCT coefficients. The system performance is tested on 40 images that contain a total of 126 nonoccluded frontal poses and the algorithm can detect 101 of them correctly. The finest details in the images and video sequences are obtained from the uncompressed domain via model based segmentation and graph matching for an in depth analysis of human bodies. The detection rate for human body parts is 70.27% for images and sequences including human body regions at different resolutions and with different postures.
