Study Notes
Image Enhancement
- Image enhancement involving neighborhood operations is an example of spatial filtering, which modifies pixel values based on neighboring pixels' values.
Purpose of Image Enhancement
- The primary purpose of image enhancement is to improve the image quality to make it more suitable for analysis, interpretation, and understanding.
- Image enhancement aims to make it easier for human viewers to extract information from the image.
Characterization of Image Enhancement
- Image enhancement can be characterized as a neighborhood operation, where the pixel values are modified based on the values of neighboring pixels.
Spatial Domain Methods
- The primary technique used in spatial domain methods of image enhancement is directly operating on the image pixels.
- Examples of spatial domain methods in image enhancement include image sharpening, noise removal, and brightness adjustment.
- Spatial filtering is a spatial domain method that modifies pixel values based on neighboring pixels' values.
- Histogram equalization is a spatial domain method that manipulates pixel values based on the distribution statistics of the entire image or local region.
Non-Spatial Domain Methods
- Frequency domain methods, which operate on the image's Fourier transform, are NOT an example of spatial domain methods in image enhancement.
Image Enhancement Operations
- Point operations, such as brightness and contrast adjustment, can remove noise, sharpen, or brighten an image as part of image enhancement.
