Resolution

Definition

Resolution refers to the ability to distinguish between closely spaced objects or details in imaging techniques and data interpretation. In the context of various applications, higher resolution implies a clearer and more detailed representation of the subject being analyzed, which is critical for accurate interpretation and decision-making.
