The amount of light can be quantified from 0 to a maximum number. RGB is an additive color model to add red, green and blue light together reproduce different colors. Each pixel is made of combinations of primary colors, e.g., for photos from a digital camera – red, green and blue – called RBG channels. If you zoom in to a raster image you may start to see a lot of little tiny squares. A pixel is a single point or the smallest single element in a display device.
In this class, we mostly concern such images. Typical images created from a camera or scanner are raster images. Another type is called a vector image which can be scaled without losing details. A typical image is a raster image whose quality would change after scaling. A digital image is a numeric representation of a two-dimensional image such as a photo. In this class, we learn how to deal with digit images. 11.2.3 Maybe we should look at unique users instead.9.3 ggplot2 - The Layered Grammar of Graphics.9.2 Data visualization using base R functions.8.3.3 File-backed memory management - Memory mapping.6.1.3 Difference between Pitch and Loudness.5.3.1 Use the API to detect the face and related information.4.5 Make sense of text data - text sentiment.4.4.2 replace space+dot with a single dot.3.7.4 When the key variable is not unique.3.7.3 Two data sets with partial same participants and variables.3.7.2 Two data sets with the same participants but different variables.3.7.1 Two data sets with the same variables but different participants.3.6.1 From wide format data to long format data.2.2.4 Get the source code of R functions.
