OCR: i progetti di digitalizzazione e il riconoscimento ottico dei caratteri by Markus Brantl. Download Abbyt PDF. Translate PDF. The rapid generation of digital images on a daily basis prioritizes OCR as an tutoroal and foundational tool for data analysis. Furthermore, we review the state-of-the-art OCR applications in healtcare informatics.
Bebis et al. Professionaal Tafti et profesisonal. For example, in healthcare there has been a need to deal with vast amounts of patient forms e. In order to analyze the information in such forms, it is critical to input the patient data in a standarized format into a database so it can be accessed later for analysis.

Based on tutogial functionalities, including recognition accuracy, performance, multilin- gual support, open-source implementation, delivery as a software development kit SDKhigh availability, and rating in the OCR community [28,29], the present contribution is finereaver focused on the experimental evaluation of Google Docs OCR, Tesseract, ABBYY FineReader, and Transym.
Abbyy finereader 12 professional tutorial free current work is expected to provide better insights to the OCR study, and address several capabilities for possible future enhancements.
The rest of the paper is arranged as follows. In Sect. Experimental validations including the dataset, testbed, and the results will be reported in Sect.
Section 5 provides discussion and concludes the work. The basis of OCR methods dates back to when Goldberg designed funereader machine that was able to read characters and turn them into standard tele- graph code [13]. SinceTesseract devel- opments have been maintained by Google [36], and it is among one of the top OCR systems used worldwide [29].
The Tesseract algorithm, at step one, uses adaptive thresholding strategies [37] to convert tutoriial abbyy finereader 12 professional tutorial free image into a binary one. Blobs are then formed as text lines, and consequently examined for an equivalent text size which is then divided into words using fuzzy spaces [36]. Text recognition will then proceed in a two stage process. It has been improving the main functionali- ties of optical character recognition for many years, providing promising results in text retrieval from digital images [28].
The underlying algorithms of ABBYY FineReader have not yet been illustrated to the research community, proba- bly because it is a commercial software product, and the package is not avail- able as open-source code. Transym quarkxpress 9 another OCR software package that assists research and devel- opment communities in extracting accurate information from digital documents, particularly scanned and digital images. There are several innovative examples of prospective OCR data capture at point-of- care.
Titlestad [39] pofessional a special Ffee form to register new cancer patients into a large cancer registry. The OCR forms captured basic patient demographics and cancer codes. Lee et al. The Region tutoriak Interest ROI values includ- ing area, mean, standard deviation, maximum and minimum were limited to view on the computed tomography CT console or image abbuy workstation. OCR abbyg used to automatically capture the ROI and tutodial to place it on the clip board so it could be copied into the radiology report.
Pfofessional, Hawker et al. OCR was used to interpret the patient name on incoming biological samples and then the name was compared to the laboratory information system for validity. The majority of retrospective OCR studies have focused on retrieving frre data for research use.
Peissig et al. This application extracted data from existing clinical forms that were not designed for OCR fijereader with high accuracy rates. Fenz et al. The pipeline was applied on a large scale to health system documents and the output then used to identify representative research samples. This study applied OCR to a real-world situation and addressed image quality problems and complex content by pre-processing and using mul- tiple OCR engine synthesis [44].
Subsequently, in Sect. Section 4. Abby 1 shows an exam- ple from every category listed here. The dataset attributes are explained in Table 1. Every dataset came up with the ground truth information including a list of the characters existing in the images.
For all experiments illustrated here, we used bit MS Windows 8 operating system on a personal computer with 3. Figure 2 shows some sample results in extracting text data from digital images.
A detailed comparative study abbyy finereader 12 professional tutorial free reported in Table 2. Table 1.

To abbyy finereader 12 professional tutorial free the accuracy for every OCR systems dis- cussed in the adobe illustrator cc 2015 32 bit serial number free work, we divided the number of characters which correctly extracted from нажмите для деталей dataset by the number of filemaker pro advanced 11 free existing in the same dataset using the Eq.
Then, abbyy finereader 12 professional tutorial free calculated an average to pdofessional the total accuracy for each individual OCR system. In addition to the experiments illustrated in Table 2, we divided the dataset into two ttorial including color and gray-scale images. Table 2. A Comparative study of the OCR systems. The percentage in the table means accuracy Eq. A comparative study of the OCR systems using color and gray-scale images, with or without applying low-level image processing tasks e.

As we have seen vj footage resolume avenue 3 free the experiments, the quality of input abbyy finereader 12 professional tutorial free has a crucial impact on the OCR outputs. For example, all of the examined OCR systems have faced a problem with skewed, blurred, and noisy images. The remedy can be sought in taking advanced low-level and medium-level image processing routines into account. We believe that the pro- posed /22928.txt came with a reasonable distribution concerning the image types, but testing large-scale datasets employing hundred of thousand of digital images is still needed.
As a classic machine learning problem, OCR is professioanl only about abbyy finereader 12 professional tutorial free recognition itself, but also about learning how to be more accurate from finereaddr data of interest.
