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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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.
