In contrast to prior art picture database browsing and retrieving methods which require the tedious opening and perusing of directories, folders and files, the present-inventive graphical user interface system (500) and method produces several display levels (100,200,300,400) of user-friendly geographical / map metaphors from picture metadata with picture icons (116, 216, 316) representing pictures captured at locations on maps. The characteristics of the display levels (100, 200, 300, 400) are programmable by the user. In the preferred embodiment, the size of the picture icons (116, 216, 316) is proportional to the number of pictures captured at the icon location.

Ten representative images are extracted from an image database storing images of a number of frames. The extracted representative images are displayed in a coordinate area, along the coordinate axes of which the image characteristics of the images are plotted, in a form in which the images are distributed in accordance with the image characteristics possessed by the extracted representative images. An image having characteristics resembling those of a required image is designated from among the representative images displayed. Images of ten frames having characteristics resembling those of the designated image are again displayed in distributed form in a coordinate area having image characteristics plotted along the coordinate axes thereof. The coordinate axes of the coordinate area displayed the second time are made more detailed than those of the coordinate area displayed the first time. As a result, images having slightly different characteristics are displayed in separated form, thereby making it easier to find the required image.

The present invention relates to a system and methodology facilitating storage, access, and version control of PLC-based images. An object is provided that mediates access between a database server and an application that desires access to such images. Before access can be achieved, a login and authentication process for a user desiring access to the image database is performed, wherein users who are successfully authenticated can then save, retrieve, and affect changes to the images in a substantially secure manner while enforcing protection against invalid or improper changes to the images. The object is adapted to store the images as a complete or compiled version of the elements required to operate a PLC program. Since PLC images are different than standard data types that are typically stored, a check-sum procedure is performed on the image to determine if changes are made. If changes are made, a metadata file that is associated with the image can log relevant change information and bump an associated revision information for the image thus facilitating automated an orderly control over who, how, when, and where such revisions can be made.

Further, the method determines the location where the specific color or color combination can be found. By analyzing the results of comparisons between the features found in the composite image and in the stored images, the tool retrieves those images that satisfy the description of the query, image. Calculation of color-related features makes significant use of the calculations that are made in the process of image compression which is an essential step prior to image storage. The process of search and retrieval on the basis of features relating to color are provided via a library of routines that perform the necessary tasks.

An image retrieval system and method that combines histogram-based features with Wavelet Frame decomposition features, as well as two-pass progressive retrieval process. The proposed invention is robust against illumination changes as well as geometric distortions. During the first round of retrieval, moment features of image histograms in the Karhunen-Loeve color space are derived and used to filter out most of the dissimilar images. During the second round of retrieval, multi-resolution WF decomposition is recursively applied to the remaining images. A set of coefficients of low-pass filtered subimages at the coarsest level, after being mean-subtracted and normalized, are utilized as features containing spatial-color information. Modulus and direction coefficients are calculated from the high-pass filtered X-Y directional subimages at each level, and central moments are derived from the direction histogram of the most significant direction coefficients to obtain TRSI direction / edge / shape features. Since the proposed invention is fast and robustness against illumination and geometric distortions, the invention is quite appealing for real-time image / video database indexing and retrieval applications.
