Transferring data between devices

Abstract: The present invention relates to a method for transferring a data file between a sending device and a receiving user equipment. The method comprises assessing, based on information relating to a transfer method and/or receiving user equipment, if the data file is to be modified. In response to finding that the data file is to be modified, the data file is modified, based on said information, into a form suitable for transferring. The data file is transferred from the sending device to the receiving user equipment. In an embodiment, the data file to be transferred is an image file and the sending device is a digital camera. The image file may be re-sized and further re-scaled for transferring.

Identifying and Tracking Digital Images With Customized Metadata

Abstract: A method of tracking digital images includes inputting data identifying a subject of an image into a camera, acquiring an image with the camera, and storing the image and the inputted data, as metadata, in an image file when the image is acquired. The method can be implemented using a scanner, a digital camera, and a data processor. The scanner obtains the identifying data and transmits the data to the camera. The camera obtains digital images and embeds the data into digital image files encoding the digital images. The identifying data has a format different from any of the formats processable by the digital camera. The data processor converts the format of the identifying data to one of the plurality of formats processable by the digital camera loads the converted information into the digital camera as metadata.

Transformation of images

Abstract: This present invention provides a system and method for transforming a main image of a digital image, such as one stored in the Exchangeable Image File (“EXIF”) format, updating the metadata, including the thumbnail image, to correspond to the transformed main image. The transformed main image and updated metadata are stored together in a file using the EXIF format so that the transformed main image may be viewed using a digital camera or viewer software compatible with a properly formatted EXIF file.

Scanning and outputting textual information in web page images

Abstract: A method, system and computer program product for scanning and outputting textual information in web page images. A file, e.g., HTML file, may be scanned for an image file tag which may identify an image file Upon identifying an image file tag, i.e. an image file, the web browser may be configured to open the image file identified by the image file tag and transfer the image associated with the opened image file to an Optical Character Recognition (OCR) scanning program. The image received by the OCR scanning program may be scanned for textual information in the image. The textual information scanned may then be transmitted to the web browser. Upon receiving the textual information, the web browser may be configured to output the textual information to a Braille display and/or speech synthesizer and/or speaker and/or display.

Integration of vector data and satellite imagery for geocoding

Abstract: The geocoding of aerial and satellite imagery is traditionally a tedious manual task. Therefore numerous initiatives for automating the geocoding procedure have been started. Among them, the EU project ARCHANGEL intends to rise a system for automated integration of Image and Map Data for Change Detection. One part of this project aims on automatic geocoding of the different satellite imagery. The approach of matching satellite imagery and vector data introduced in this paper can be characterized by the use of area objects. Area features are considered to be a subset that can be extracted from both vector data and satellite images. Hence these features represent a senseful basement for the matching process. For the vector side of the processing chain a common vector format was developed which allows the import of vector data from different data bases, for example the German ATKIS data base, vector maps in DXF format or GDF data. Based on this data structure further processing steps like extraction of polygons or selection of certain object classes or layers can be applied. In order to obtain a set of matchable area features the preprocessed vector data are rasterized to be fed into the matching process. Within the image baseline satellite images of various sources like SPOT XS, Landsat TM, MOMS and others can be imported into a uniform image format. Based on this image format a segmentation process is applied to obtain area features from the image data. The applied matching procedure calculates polygon statistics from both the preprocessed and rasterized vector data set and the segmented satellite imagery. In our approach additionally a set of transformation coefficients obtained from a manual tie point editing is used to support the polygon matching. The matching routine subsequently compares the polygon area, the length of the perimeter, the position of the centroid, and the chain frequency of pairs of polygons.
