    What is an image

    • A matrix of intensity values (grid).
    • Using one byte per value (0 = black, 255 = white)
    • A digital image is a sampled, quantized version of a function (f(x, y)).

    What is an image (continued)

    • The function maps coordinates (x,y) to intensities
    • Visual representation of the image

    Image Categorization

    Imaging more broadlyand in medical applications

    • Electromagnetic spectrum (EM) imaging (gamma to radio waves) is used in imaging beyond the visible.
    • Imaging techniques, like in Radio, Microwave, Infrared bands, are used to observe situations not visible to the naked eye.

    Imaging more broadlyand in medical applications (Continued)

    • Other applications based on gamma rays include Nuclear medicine, bone scans, and PET scans for medical use, and astronomical observations.
    • Additional techniques include applications of X-ray imaging for industrial use.
    • Other techniques and applications based on UV light, and infrared, for other applications

    Other Applications for Visible Range

    • Examples: Fingerprint scans, currency validation (such as banknotes), and automatic license plate recognition.

    Building a system for Image Processing

    • Image sensors, specialized hardware, image processing software, mass storage, computer, and image displays are the vital components.
