Basic Image Filtering Operations

Image filtering involves the application of window operations that achieve useful effects, such as noise removal or image enhancement. This chapter deals particularly with what can be achieved with quite basic approaches, such as application of local mean, median, or mode filters to digital images. The focus is on gray-scale images, though some aspects of color processing are also covered.

Look out for:

• what can be achieved by low-pass filtering in the spatial frequency domain.

• how the same process can be carried out by convolution in the spatial domain.

• the problem of impulse noise and what can be achieved with a limiting filter.

• the value of median, mode, and rank order filters.

• how computational ...
