# Pixel Space

Pixel space is similar to root space, except that VisionPro does not adjust it to reflect the effect of image processing operations. The origin of pixel space is always the upper-left corner of the upper-left pixel. If you subsample an image, the locations of features will be different in the subsampled image's pixel space than they were in the original image's pixel space.

In general, pixel space is rarely useful for applications, although it can be useful when specifying graphics for display.
