Skaitļu atpazīšana brīvā dabā uzņemtās fotogrāfijās

subject

OCR Datorzinātne rakstzīme pirmapstrāde Python

description

Palielinoties digitālo tehnoloģiju lomai cilvēku ikdienā, OCR jeb Optiskā teksta pazīšana kļūst arvien biežāk izmantota. OCR pielietojumu iespējas ir plašas – kā vienu no biežāk izmantotajām var minēt dokumentu digitalizēšanu – tomēr brīvā dabā uzņemtās fotogrāfijās ar skaitļiem OCR precizitātei vēl joprojām ir vieta izaugsmei. Darba mērķis ir noteikt, cik liela loma un ietekme ir OCR tehnoloģijām mūsdienās un kāpēc tās efektivitāte krīt, analizējot attēlus ar skaitļiem. Darba uzdevumi ietver iepazīšanos ar OCR tehnoloģijas vēsturi un pielietojumiem mūsdienās, tehnoloģijas algoritmiem un trūkumiem tajos. Darba pētījumā tika izpētīti divi OCR rīki, izmantojot programmēšanas valodu Python, un rezultātā tika analizēta to precizitāte.
