Abstract
A camera of a computing device can capture two or more images of a region including an object of interest, in order to allow for separation of the object from a background of the images through a process such as image subtraction. In order to compensate for rotations of the device between image captures, an element such as an electronic gyroscope can be used to monitor changes in orientation and predict an amount of shift of objects between images. The predicted shift can be used to attempt to align images captured around the time of the rotation, in order to enable subtraction or similar processes by effectively removing the shifting effect of the rotation.
