WebFeb 23, 2024 · K-means will be applied to image compression. In a straightforward 24-bit color representation of an image, each pixel is represented as three 8-bit unsigned integers (ranging from 0 to 255) that specify the red, green and blue intensity values. This encoding is often refered to as the RGB encoding. WebNov 24, 2015 · K-means is a clustering algorithm that returns the natural grouping of data points, based on their similarity. It's a special case of Gaussian Mixture Models. In the image below the dataset has three dimensions. It can be seen from the 3D plot on the left that the X dimension can be 'dropped' without losing much information.

WebMay 28, 2024 · In our problem of image compression, K-means clustering will group similar colors together into ‘k’ clusters (say k=64) of different colors (RGB values).
