Image classification is a fundamental task in remote sensing and image interpretation that involves the process of categorizing or labeling pixels or regions within a digital image into predefined classes or categories based on their characteristics, such as spectral, spatial, and textural properties. This technique plays a critical role in a wide range of applications, including land cover mapping, environmental monitoring, urban planning, agriculture, forestry, and disaster management. It enables us to extract valuable information from remotely sensed images, facilitating better decision-making and resource management.

Two common approaches to image classification in remote sensing are:

1. Supervised Classification:
   Supervised classification is a method that relies on prior knowledge of the image data to train a classification algorithm. In this approach, an analyst selects a representative set of sample pixels, often referred to as training samples, from the image. These training samples are chosen from different classes or categories that the analyst aims to identify in the image. The analyst then manually assigns labels to these samples, indicating their corresponding class or category.

   The classification algorithm is trained using these labeled training samples, which helps the algorithm learn the spectral signatures and spatial patterns associated with each class. Some commonly used supervised classification
