Pixel Response Non-Uniformity (PRNU) refers to the variation in sensitivity and response of individual pixels on an image sensor, which can result in fixed-pattern noise in digital images. This phenomenon is primarily caused by manufacturing imperfections and can affect image quality, necessitating calibration and correction techniques in imaging systems.

An image sensor is a crucial component in digital cameras and imaging devices that converts light into electronic signals, enabling the capture of images. It plays a vital role in determining the quality and resolution of the captured image, with common types including CCD and CMOS sensors, each having distinct advantages and applications.

Fixed-Pattern Noise is like a picture with tiny spots that never move, even if you take the picture again. It's like when you draw with a crayon and some parts are always a little darker or lighter, no matter how many times you color it in the same way.

Fixed-Pattern Noise

Digital images are a matrix of pixels, each representing a specific color or intensity, forming a visual representation that computers can store and manipulate. They are essential in diverse fields such as photography, medical imaging, and digital art, providing a foundation for image processing and analysis.

Image quality refers to the perceived clarity, detail, and visual fidelity of an image, often influenced by factors such as resolution, color accuracy, and noise. It is crucial in various fields such as photography, medical imaging, and digital media, where high image quality can significantly impact the effectiveness and interpretation of visual information.

Image Quality

Calibration techniques are essential processes in various fields to ensure that instruments and models produce accurate and reliable results by aligning their outputs with known standards or reference points. These techniques involve adjusting, fine-tuning, and validating the performance of devices or algorithms to minimize errors and improve precision.
