Spillover (imaging)

Spillover (also known as bleed or halo) is a phenomenon in imaging where the signal from one pixel spills over into adjacent pixels. This can occur in various types of imaging, including photography, microscopy, and medical imaging.

Causes

Spillover can be caused by a variety of factors, including:

• Diffraction: This is the bending of light waves around obstacles or through openings, which can cause the light to spread out and affect adjacent pixels.
• Scattering: This is the redirection of light in various directions, which can cause it to reach adjacent pixels.
• Reflection: This is the bouncing of light off surfaces, which can cause it to reach adjacent pixels.
• Refraction: This is the bending of light as it passes from one medium to another, which can cause it to reach adjacent pixels.

Effects

The effects of spillover can include:

• Reduced image quality: Spillover can cause images to appear blurry or fuzzy, reducing their overall quality.
• Misinterpretation of data: In scientific and medical imaging, spillover can lead to incorrect interpretations of the data, potentially leading to incorrect diagnoses or conclusions.

Prevention and Correction

There are several methods for preventing and correcting spillover, including:

• Use of high-quality equipment: High-quality imaging equipment can help to reduce the likelihood of spillover.
• Proper calibration of equipment: Regular calibration of imaging equipment can help to ensure that it is functioning correctly and reduce the likelihood of spillover.
• Use of image processing techniques: Various image processing techniques can be used to correct for spillover after the image has been captured.
