What is Image Data?

Image data consists of a grid of pixels, where each pixel represents color intensity. These intensities can be stored as:

• Grayscale: Single intensity values (0–255).
• RGB: Three intensity values for red, green, and blue channels.

Images are essentially numerical data that can be processed by computers.

How Images are Represented Digitally

Images are represented as multidimensional arrays:

• Grayscale Images: 2D arrays (Height × Width).
• Color Images: 3D arrays (Height × Width × Channels).

For example, a 100×100 RGB image is represented as a 100×100×3 array.
