Medicál Imagees of tein contain noise that can hinder precositis diagnosis and analysis. Applying signal processing technolques helps improve improve impice quality by reducing tis noise while conservig important details.

Types of Noise in Medicál Images

Common noise type include Gaussian noise, salt- and -peppepper noise, and speckle noise. Each type affects impies differtly and requires specific processing metods to effively reducte.

Signol Processing Techniques for Noise Reduction

Various technokes are used to enhance medical el images by reducing noise. These methods aim to improvce clarity with out losing criminad information.

Filtering Method

Filtering technokes such as median filtering and Gaussian filtering are common used. Median filters are efuttive against salt- and -peppernoise, while Gaussian filters smooth out Gaussian noise.

Transform Domain Techniques

Transform domain methods, like wroneet denoising and Fourier filtering, work by transforming the image into a differt domain, reducing noise provints, and then transforming back to the spatiad domain.
