# Remapping Pixel Values

The Intelligent Pixel Map tool is the easiest way to map pixel values of an input image to an output image. For example, you can map the pixel values of a CogImage16Grey image to a CogImage8Grey image.

Once the Intelligent Pixel Map Tool gets the input image, it automatically generates a mapping based on the histogram data to enhance the visual features on the picture. If the result is not what you expected, it is possible to manually map the pixels.

This capability allows you to:

- Reduce 16-bit images to 8-bit images while selectively preserving specific ranges of pixel values.
- Increase the visibility of image features with low contrast by selectively expanding the range of pixel values of the features of interest. This allows you to provide for enhanced visualization of defects in X-ray and thermal images.
- Create composite pixel mapping functions that allow you to apply different linear mappings to different ranges of input pixel values. This allows you to extract and combine specific temperature ranges from a thermal camera.
