Tuwo is a C++ library for solving high-level computer vision tasks such as image classification and object recognition. Computer vision is a subfield of computer science and deals with systems that can make sense of image information. Building systems suited for high-level computer vision tasks such as object recognition and image classification requires the use of robust image statistics in the form of image features and machine learning algorithms to separate discriminative information from noise. This C++ library provides code to extract image features and learn decision functions from training data. It is suitable for high-level computer vision tasks.
