Filtering

The EasyImage filters combine each pixel with its neighbors, in the spatial or in the frequency domain.

Linear Filtering

Highlight features with linear combinations of neighboring pixels (convolution).

Linear Filtering
Non-Linear Filtering

Highlight shapes or remove noise with morphological operations and median filtering.

Non-Linear Filtering
Noise Reduction and Estimation

Reduce the noise so that it does not influence the other operations.

Noise Reduction and Estimation
Gabor Filter

Analyze textures or create features for a classifier.

Gabor Filter
Fourier Transform

Represent an image by its frequency components to perform specific filtering.
