In digital imaging, a matrix is essentially the framework that defines the image.
Based on the provided reference:
A matrix is a square arrangement of numbers in columns and rows. Think of it like a grid. In the context of digital imaging, the numbers within this grid are crucial because they correspond to discrete pixel values.
Here's a breakdown of how it works in imaging:
- Structure: The matrix is organized into a specific number of columns and rows, forming a square or rectangular grid.
- Contents: Each individual box, or cell, within this grid contains a number.
- Pixel Values: In digital imaging, each number corresponds to the value of a single picture element, known as a pixel. This value typically represents characteristics like brightness or color intensity at that specific point.
- Location and Correspondence:
- Each box within the matrix also corresponds to a specific location in the overall image display.
- Crucially, this location and the pixel value associated with it corresponds to a specific area of the patient's tissue in medical imaging, representing information gathered from that physical location.
Essentially, the matrix is the digital blueprint of the image, where each cell holds the data (pixel value) for a specific point that corresponds to a real-world location.
