Aug 22, 2018 What are the best open source OCR libraries? Update Combined with the Leptonica Image Processing Library it can read a wide variety of image formats and convert them to text in over 60 languages. It was one of the top 3 engines in the 1995 UNLV Accuracy test. supporting C, Perl, ObjectiveC, Ruby, etc. Other open source OCR library I What is FreeImage?
FreeImage is an Open Source library project for developers who would like to support popular graphics image formats like PNG, BMP, JPEG, TIFF and others as needed by today's multimedia applications. The CImg Library is a small and opensource C toolkit for image processing, designed with these properties in mind: CImg defines classes and methods to manage images in your own C code.
OpenCV (Open Source Computer Vision Library) is released under a BSD license and hence its free for both academic and commercial use. It has C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS and Android. OpenCV was designed for computational efficiency and with a strong focus on realtime applications.
Here is a list of useful opensource libraries dedicated to the programming of image processing algorithms, which you can download and use for free.
C The CImg Library is a popular, small, comprehensive, open source C toolkit for image processing. I've been looking around for a simple and small yet robust and fast (not comprehensive!
) image library for C (C would suffice, if no C version is available). Main features I'm looking for are: Free (opensource is a plus) The Simd Library The is a free open source image processing library, designed for C and C programmers. It provides many useful high performance algorithms for image processing such as: pixel format conversion, image scaling and filtration, extraction of statistic information from images, motion detection, object detection (HAAR and LBP classifier cascades) and classification, neural network.
A list of open source C libraries. From cppreference. com cpp Folly Facebook opensource library. Library of C11 components designed with practicality and efficiency in mind. GraphicsMagick Reading, writing, and manipulating images in over 88 major formats. Forked from ImageMagick in 2002 Emgu CV is an open source library that uses the OpenCV library as a basis for its image processing features.
It works by allowing OpenCV core functions and functionalities to be called by any. NET language (including C# ). I want a C# library for that is open source and free. I want this library do optimization or thumbnail creation based on real algorithms that are standard.
