Image Clustering

K-Means Clustering is a technique used in data analysis, In the field of image processing with large datasets like rasters. It groups similar pixels together based on their values across multiple channels. Imagine each pixel as a data point with various attributes (channels). K-Means identifies ‘k’ groups (clusters) so that pixels within each group are more similar to each other than to those in other groups. This helps in segmenting the raster into meaningful regions, making complex data more manageable for further analysis.

The ‘k’ parameter in K-Means represents the predetermined number of clusters you want to identify in the data. Choosing the right ‘k’ is crucial, as it directly impacts the granularity of segmentation. A higher ‘k’ value will result in finer, more detailed clusters, but may lead to over-segmentation. Conversely, a lower ‘k’ value may result in fewer, broader clusters, potentially missing important distinctions in the data.
