Object-Based Image Analysis (OBIA) is an advanced technique used in remote sensing and image processing. It focuses on segmenting and classifying images based on objects rather than individual pixels. By considering spatial, spectral, and contextual information, OBIA allows for more accurate and detailed analysis of complex scenes. It finds applications in diverse fields such as land cover mapping, urban planning, and environmental monitoring, providing valuable insights for informed decision-making and resource management.
OBIA, which stands for Object-Based Image Analysis, is a methodology used in remote sensing and image processing. It involves the segmentation and classification of images based on objects or meaningful entities, rather than individual pixels. By grouping pixels into objects and considering their spatial, spectral, and contextual characteristics, OBIA allows for more accurate and detailed analysis of complex scenes. This approach is widely used in various fields, including land cover mapping, urban planning, environmental monitoring, and natural resource management. OBIA provides valuable insights and supports decision-making processes in these domains.
