Image Filtering and Enhancement

Contrast adjustment, morphological filtering, deblurring, ROI-based processing

Image enhancement is the process of adjusting images so that the results are more suitable for display or further image analysis. For example, you can remove noise, sharpen, or adjust the contrast of an image, making it easier to identify key features.

Categories

Image Filtering
Convolution and correlation, predefined and custom filters, nonlinear filtering, edge-preserving filters

ROI-Based Processing
Define and operate on regions of interest (ROI)
Morphological Operations
Dilate, erode, reconstruct, and perform other morphological operations
Deblurring
Deconvolution for deblurring
Neighborhood and Block Processing
Define neighborhoods and blocks for filtering and I/O operations
Image Arithmetic
Add, subtract, multiply, and divide images
