When a regression model is built, we may apply not only at object level but also at pixel level using the Regression toolbar button. The pixel visualization of regression output allows us to understand inhomogenities within the objects and spatial distribution of the modeled phenomena.



The display shows only the foreground pixels


The Visualization tab provides a number of options to fine-tune the rendering of the estimated output. In the following example, we stretch the min and max values of the rendering, this can be done either via edit boxes or by a mouse-wheel in the left-lower or right-upper corner of the regression plot:


Before stretch:


After stretch:


Note that the floating point regression output does not change, we only affect its rendering via the specified color map and visualization settings. For more information on color map control, see the description in the visualization section.
