Detailed Technical Solution & Explanation
The standard fundamental sequence of steps in digital image processing (as formulated by Gonzalez & Woods) proceeds logically from low-level sensory acquisition to high-level symbolic interpretation:
Option Analysis:
•
Option A (Image Acquisition → Feature Extraction → ...): Incorrect. Feature extraction cannot precede preprocessing and segmentation.
•
Option B (Image Acquisition → Preprocessing → Segmentation → Feature Extraction → Image Analysis → Post-processing → Output): Correct. Accurately represents the canonical hierarchy from pixel-level preprocessing to object segmentation and semantic analysis.
•
Option C (Feature Extraction → Image Acquisition → ...): Incorrect. An image must be acquired before any features can be extracted.
•
Option D (Segmentation → Image Acquisition → ...): Incorrect. Segmentation cannot occur prior to image acquisition.
