Artefacts are unwanted features or distortions that appear in images. They can happen in different types of imaging, especially in scientific fields like astronomy and x-ray imaging.

#Causes of Artefacts

These problems can occur due to various reasons such as:

• Reflected or scattered light in astronomical images.
• Blurring caused by small structures that are not resolved in x-ray images.
• Intensity changes near the edges of samples in x-ray images.

#Effects of Artefacts

Artefacts can interfere with the quality of images, making it harder to see the true details. This can lead to incorrect conclusions when scientists analyze the data.

#Detecting and Correcting Artefacts

To improve image quality, scientists use special techniques to find and remove these artefacts. In astronomy, machine learning helps identify artefacts in images from telescopes. In x-ray imaging, methods are used to clear up blurring and other unwanted signals to get a clearer picture.

#Importance of Addressing Artefacts

By reducing artefacts, scientists can make better observations and gain more accurate information from their data. This is important for research and helps in understanding more about our universe and materials on a small scale.
