This paper reports the results of a study on a first sight decision tree algorithm for cursive script recognition based on the use of histogram as a projection profile technique. A postal code image data scanned is converted in a 2-dimension matrix representation to be used with a set of algorithms to provide full range segmentation. The results, based on(More)
Teleradiology is one of the most evolved areas of telemedicine, but one of the basic problems which remains unsolved concerns system compatibility. The DICOM (Digital Imaging and Communications in Medicine) standard is a prerequisite, but it is not sufficient in all aspects. Examples of other currently open issues are security and cooperative work in(More)
