The spatial domain refers to the analysis and processing of signals or images based on their location in space, as opposed to their frequency components. It is essential for tasks such as image enhancement, filtering, and spatial transformations, where operations are performed directly on the pixel values of an image.

Frequency components refer to the individual sinusoidal waves that, when combined, form a complex signal or waveform. Understanding these components is crucial for analyzing and manipulating signals in fields such as telecommunications, audio engineering, and digital signal processing.

Image enhancement involves improving the visual appearance of an image or converting it to a form better suited for analysis by a human or machine. Techniques in image enhancement aim to accentuate certain features or remove artifacts to facilitate interpretation and analysis.

Image filtering is a process used to enhance or alter the appearance of an image by manipulating its pixel values, often to reduce noise or highlight specific features. It is a fundamental operation in image processing that employs various algorithms to achieve desired effects, such as smoothing, sharpening, and edge detection.
