Understanding Pixel Values in Images Examining images reveals the numeric values at each pixel, which represent different intensities. By zooming into an image like a mandrill, one can observe details and associated numerical data for specific regions. A small red box highlights variations in color intensity within this area, showcasing how close examination uncovers both visual and quantitative information about the image.
Visualizing Image Data as Matrices Analyzing slices of an image along x and y axes provides insights into changes in pixel intensity across rows or columns. Darker values indicate lower intensities while brighter ones signify higher shades towards white. This analysis suggests that images can be represented as matrices where each element corresponds to a pixel's intensity value ranging from 0 (black) to 255 (white), illustrating various shades of gray between these extremes.
