Starting with OpenCV on i.MX 6 processors
Wednesday, November 22, 2017 Introduction As the saying goes, a picture is worth a thousand words. It is indeed true to some extent: a picture can hold information about objects, environment, text, people, age and situations, among other information. It can also be extended to video, that can be interpreted as a series of pictures and thus holds motion information. This might be a good hint as to why computer vision (CV) has been a field of study that is expanding its boundaries every day. But then we come to the question: what is computer vision? It is the ability to extract meaning from an image, or a series of images. It is not to be confused with digital imaging neither image processing , which are the production of an input image and the application of mathematical operations to images, respectively. Indeed, they are both required to make CV possible. But what might be somehow trivial to human beings, such as reading or recognizing people, is not always true when
