2.0 Filters, Operators and Algorithms
Operations can be on:
- A pixel at a time on:
- a single image
- two images
- A sliding local window (square, rectangle or other shape in an image (e.g. Fast Fourier Transform)
- Applied to the entire image or a
specified region of the image
- An image to extract a sub-image, which may not be rectangular (called segmentation - involving thresholding and cropping)
- Measurements for use in classifying or identifying what a sub-image represents (e.g. a via vs. a short between lines), creating a multidimensional feature space
