Image Processing Library functions perform a variety of tasks related to image processing.

This section is organized as follows.

- The Basic Concepts chapter provides an overview of the information contained in the functional descriptions.
- The Library Version chapter describes the function that provides library version information.
- The Support Functions chapter describes FW functions that support other FW functions.
- The Image Data Exchange and Initialization Functions chapter describes functions that set the initial value of an image data buffer, copy data from one buffer to another, convert data type, and scale image data.
- The Arithmetic and Logic Functions chapter describes general-purpose mathematic functions and functions that perform specific mathematic operations related to image processing.
- The Color Model Conversion Functions chapter describes functions that convert image data from one color model or space to another.
- The Statistical Functions chapter describes FW functions which perform statistical operations on image data.
- The Threshold and Compare Functions chapter describes functions that compare image data and manipulate image data based on compare operations.
- The Morphological Operations chapter describes functions that warp, shear, resize, mirror, and rotate images.
- The Digital Filter Functions chapter describes functions that alter frequency-related visual properties of images such as sharpness and contrast.
- The Linear Transformation Functions chapter describes functions for Discrete Cosine Transform (DCT).
- The Geometric Transform Functions chapter describes functions that warp, shear, resize, mirror, and rotate images.
- The 3D Look-up functions chapter describes functions for 3D look-up with trilinear interpolation.

Within the section, the **Basic Concepts** chapter provides overview information related to the functions in the library,
and subsequent chapters provide detailed descriptions of library functions that perform operations of the same kind.

Each detailed description consists of a **Function Name** followed by a short description, a **Synopsis** of the function syntax,
a list of function **Parameters**, a detailed **Description** of the function, and a list of **Return Values.**

When a function is optimized for one or more technologies, a list of **Supported Technologies** is provided after the short description.

The Function Quick Reference provides an index and snapshot view of function optimizations.
