Invert Colors

Overview

Inverts image intensity values using MATLAB imcomplement.

Bright values become dark and dark values become bright according to the numeric range of the working data.

• An inverted intensity display makes structures easier to inspect.
• Comparing positive and negative visual contrast.
• Preparing an alternative visualization of the current cube.

Important

Invert Colors modifies the current working cube in memory.

It is not merely a display-colormap change.

Interpretation depends on the numeric range and datatype of the input data.

Use caution when working with data that are not already on a conventional

Workflow

1. Load a hyperspectral dataset.

2. Inspect the inverted result.

3. Use Reset Filters to restore the original working data if required.
