Witryna25 mar 2024 · We start with the RGB model. In short, it is an additive model, in which shades of red, green and blue (hence the name) are added together in various proportions to reproduce a broad spectrum of colors. In scikit-image, this is the default model for loading the images using imread: image_rgb = imread ('crayons.jpg') WitrynaEach inner list represents a pixel. Here, with an RGB image, there are 3 values. Since it's a black and white image, R, G, and B are all similar. An RGBA (where A is alpha, or transparency) has 4 values per inner list, and a simple luminance image just has one value (and is thus only a 2-D array, not a 3-D array).
