Computer Vision 4 Art (CVA) CVA consists of an image acquisition system such as a video camera, a photographic camera, a multispectral camera, or a scanner, image preprocessing, image processing, and image analysis algorithms. CVA works as an online or offline system; in an online CVA the algorithms are implemented as hardware/firmware in an image acquisition system, and in an offline CVA the algorithms are implemented as application software in a computer, iPad, iPhone, or a similar device. CVA enables everyone to be a creative artist. All the images in this book are generated by CVA.
