Mixed pixels are points in LADAR data which occur when the measurement beam intersects
two objects at within a certain range of distances apart. The resulting return
signal represents data from both objects; the laser electronics read this as a single point,
but not at the real location of either object. As such, mixed pixels present an obstacle
to accurate analysis of a scene. We present a survey of mixed pixel phenomena and a
method of removing mixed pixels from scenes stored as 3-D points. Our method does
not depend on the sensor used to originally collect the data, and is efficient and effective.
