Prev Tutorial: Adding (blending) two images using OpenCV[1]
Next Tutorial: Discrete Fourier Transform[2]
GoalIn this tutorial you will learn how to:
Access pixel values Initialize a matrix with zeros Learn what cv::saturate_cast[3] does and why it is useful Get some cool info about pixel transformations Improve the brightness of an image on a practical example Theory NoteThe explanation below belongs to the book Computer Vision: Algorithms and Applications[4] by Richard SzeliskiImage Processing A general image processing operator is a function that takes one or more input images and produces an output image. Image transforms can be seen as:Point operators (pixel transforms) Neighborhood (area-based) operators Pixel Transforms In this kind of image processing transform, each output pixels value depends on only the corresponding input pixel value (plus, potentially, some globally collected information or parameters). Examples of such operators include brightness ...取得本站獨家住宿推薦 15%OFF 訂房優惠
