The correct answer is 'Spatial feature manipulation'

Key Points

  • Spatial feature manipulation:
    • Spatial feature manipulation involves enhancing specific spatial features in an image to improve its interpretability.
    • This procedure can include operations such as edge enhancement, contrast enhancement, and filtering to highlight or suppress certain features.
    • Spatial feature manipulation helps in making the important details of the image more visible and distinguishable.
    • This technique is commonly used in applications like satellite imagery analysis, medical imaging, and various other fields requiring detailed image interpretation.

Additional Information

  • Radiometric Correction:
    • Radiometric correction is a preprocessing step that adjusts the digital image values to correct sensor and atmospheric effects.
    • It ensures that the image accurately represents the reflected or emitted radiation from the Earth's surface.
  • Geometric Correction:
    • Geometric correction involves rectifying the geometric distortions in an image to ensure that the spatial coordinates match the real-world coordinates.
    • This process is essential for accurate mapping and spatial analysis.
  • Noise Removal:
    • Noise removal is a preprocessing step that involves eliminating random variations in image data, which can be caused by sensor errors, environmental conditions, or other factors.
    • This step helps in improving the clarity and quality of the image by reducing unwanted noise.
