Imagine that you want to scan a magazine article or a printed contract. You can spend hours typing everything again and fixing errors, or you can use the best optical character recognition software. What is OCR? OCR is nothing but a modern technology that allows you to convert different types of documents, PDF files, or images captured by any digital means (digital camera, smartphone camera, webcam) into editable and searchable data. There are two types of text recognition technologies: OCR and ICR. OCR serves for the recognition of printed text, while ICR helps to process handwritten text. In this article, you will discover all the features of OCR. Good reading.
How accurate is the OCR?
The accuracy of Solvio optical character recognition software is usually measured at a character level. 99% accuracy means that one character out of 100 is recognized as “uncertain”. 99.9% accuracy means that one character out of 1000 is recognized as uncertain. When OCR companies develop and optimize recognition technology, they can only measure the resulting recognition accuracy through a given set of sample images/documents with known and 100% correct text. It means that an absolute measurement is impossible in real life, as there is usually not 100% accurate data.
For English alphabets, OCR text recognition software is almost 100% accurate for high-quality documents. For languages that use complex scripts, the accuracy is lower to medium but still very high compared to other alternatives. The OCR software provides special verification tools with the original image and its recognition on the same screen. The program helps you to compare results quickly and correct errors if there are any.
How to get better OCR accuracy?
Any scanning utility allows you to change this parameter. By default, any OCR software requires a minimum resolution of 300 dpi for high recognition accuracy. The best OCR text recognition software can also process images at low resolution but with modest expectations of accuracy. In complex script texts, the quality of the image resolution becomes critical due to the high complexity of the characters used.
If the document is complex for recognition by the human eye, then the recognition results will also be poor. If the color of the document’s font is close to the background of the paper or if the background is very colorful, then the information may be lost when converting the image to black and white. It sounds curious, doesn’t it? Now you know what OCR is and what peculiarities are hidden in the development of this technology.
Discover the benefits of using OCR
Using OCR in your documents, you can perform internal searches, cut out the desired part of the content and use it in a new copy. With these features, your time is optimized, as you don’t have to read a contract for hours to find information. Not to mention that information sharing is faster, and this influences the efficiency of decision-making in the company. Suppose you received an email and need to search for some vital information in it. To do this, you need to use OCR.
Hebu wazia kwamba unataka kuchunguza makala ya gazeti au mkataba uliochapishwa. Unaweza kutumia saa kuandika kila kitu tena na kurekebisha makosa, au unaweza kutumia bora optical tabia utambuzi programu. OCR ni nini? OCR ni teknolojia ya kisasa ambayo inaruhusu kubadilisha aina tofauti za nyaraka, faili za PDF, au picha zilizochukuliwa na njia yoyote ya dijiti (kamera ya dijiti, kamera ya simu ya rununu, kamera ya wavuti) kuwa data inayoweza kuhaririwa na kutafutwa. Kuna aina mbili za teknolojia ya utambuzi wa maandishi: OCR na ICR. OCR ni mfumo wa kutambua maandishi yaliyochapishwa na kuweza kuunganisha maandishi yaliyoandikwa kwa mkono. Katika makala hii, utapata maelezo ya kina ya OCR. Usomaji mzuri. OCR ni sahihi kadiri gani? Usahihi wa Solvio optical tabia utambuzi programu ni kawaida kipimo katika tabia ngazi. "Ukweli wa 99% una maana kwamba herufi moja kati ya 100 inatambuliwa kama ""haijulikani.""" "Ukweli wa 99.9% unaonyesha kwamba alama moja kati ya 1000 haijulikani kuwa sahihi.""" Kampuni za OCR zinapoboresha teknolojia ya utambuzi, zinaweza kupima usahihi wa utambuzi kupitia seti fulani ya picha za sampuli na maandishi yanayojulikana na sahihi. Kwa hivyo, kwa kweli, hakuna uwezekano wa kupima kwa ukamilifu, kwa sababu kwa kawaida hakuna data sahihi ya 100%. Kwa maandishi ya Kiingereza, programu ya utambuzi wa maandishi ya OCR ni karibu 100% sahihi kwa hati za ubora wa juu. Kwa lugha ambazo hutumia maandishi magumu, usahihi ni chini hadi wa kati lakini bado ni juu sana ikilinganishwa na mbadala nyingine. Programu ya OCR hutoa zana maalum za uthibitisho na picha ya awali na utambuzi wake kwenye skrini moja. Programu hiyo inakusaidia kulinganisha matokeo haraka na kurekebisha makosa ikiwa yapo. Jinsi ya kupata usahihi bora wa OCR? Yoyote scanning huduma inaruhusu wewe kubadilisha parameter hii. Kwa default, programu yoyote OCR inahitaji kiwango cha chini cha azimio la 300 dpi kwa usahihi wa utambuzi wa juu. Programu bora ya utambuzi wa maandishi ya OCR pia inaweza kusindika picha kwa azimio la chini lakini kwa matarajio ya wastani ya usahihi. Katika maandishi tata ya maandishi, ubora wa azimio la picha inakuwa muhimu kutokana na utata wa juu wa wahusika wanaotumiwa. Kama hati ni ngumu kwa ajili ya utambuzi na jicho la binadamu, basi matokeo ya utambuzi pia itakuwa duni. Kama rangi ya font ya hati ni karibu na background ya karatasi au kama background ni rangi sana, basi habari inaweza kupotea wakati wa kubadilisha picha kwa nyeusi na nyeupe. Hilo laonekana kuwa jambo la kushangaza, sivyo? Sasa unajua nini OCR ni na nini peculiarities ni siri katika maendeleo ya teknolojia hii. Kutumia OCR katika hati zako, unaweza kufanya utafutaji wa ndani, kukata sehemu inayohitajika ya maudhui na kuitumia katika nakala mpya. Pamoja na vipengele hivi, muda wako ni optimized, kama huna kusoma mkataba kwa saa kupata habari. Bila kutaja kwamba kushiriki habari ni haraka zaidi, na hii inaathiri ufanisi wa maamuzi katika kampuni. Tuseme umepokea barua pepe na unahitaji kutafuta habari fulani muhimu ndani yake. Ili kufanya hivyo, unahitaji kutumia OCR.
