The Fundamentals of Image Processing: Enhancement and Transformation
The simplest form of enhancement, where each pixel is modified based solely on its own value. Common examples include brightness adjustment and contrast stretching. CDVIP-LB02A.7z
Used to resize or reorient images. These require Interpolation (such as Nearest Neighbor or Bilinear) to estimate pixel values when the new grid does not align perfectly with the old one. These require Interpolation (such as Nearest Neighbor or
These include translations, shears, and rotations while preserving collinearity. They are the mathematical foundation for "rectifying" images taken from tilted angles. 3. Practical Implementation and Tools CDVIP-LB02A.7z
Using Gaussian blurring to remove high-frequency noise. 4. Conclusion
Modern implementation of these concepts relies heavily on libraries such as and NumPy in Python. A typical workflow involves: Preprocessing: Normalizing pixel values to a 0–1 range.
