Analyze images

Analyze images command produces a report of color distribution of the images in the active image list. The report contains information about the average red, green, blue, intensity, saturation, and contrast values. The values are computed for each image and averaged for images of one camera or time intervals.

The values from the report may give some idea for systematic Color corrections.

To analyze images:

1. (Optional) Select images in the image list or draw a fence to identify images which you want to analyze.

2. Select Analyze images command from the Utility pulldown menu.

This opens the Analyze images dialog:
