About qv

qv (quick view) is a viewer for 2D data such as images, renderings, sensor data, videos etc.

qv shows images and image-like data and provides analysis tools such as statistics, histogram, range selection, dynamic range reduction, and color maps.
It is useful for all kinds of 2D data from sensors, simulation, rendering, or high dynamic range imaging.
Here are some screen shots to demonstrate how it works:
