In order to read a graphic file in MATLAB, you can use the Imread function. Level is the threshold level (which should be between 0 and 1). For this purpose, we use the rgb2gray command to convert the color command to a gray image. Digital images are usually more or less noisy. Noise removal must be done before any processing operation. Numerous filters are designed to eliminate noise. MATLAB also has several filters to remove noise. The simplest of these is the middle and middle filter.We use the medfilt2 function to apply the middle filter.

After loading the signal, as you can see, there is a noise signal, so for further processing, we need to
have a signal without noise or with minimal noise. To find out if our noise is high or low frequency, we
take the signal to the frequency domain and check it there. To remove noise, we need to have noise
information and be able to delete the noise information to reduce the noise. But we do not have any
previous information about noise and we have to get this information somehow.

Breast cancer accounts for 19% of deaths caused by cancers and 24% of all cases afflicted to cancers in European countries. Approximately 25% of breast cancer deaths happen in women between the ages of 40 and 49. Anomaly detection is done by the separation of the initial steps in computer detection systems. In this chapter, while reviewing the different techniques, a qualitative comparison between them will be provided. In this study, two approaches for the presentation of mammography (comparison of previous and current mammography images) are evaluated: together (simultaneously) and alternately on the same screen.
