Abstract
By collecting, analyzing and processing a series of images captured by a camera one can estimate the motion that a device containing the camera has experienced. Exemplary techniques disclosed herein at least enable device motion estimation based on any selection of images from a camera related to the device.
Claims11
A method of estimating motion of a device comprising:
- storing at least two consecutive frames of an image in at least one memory location on the device,
- downsampling to eliminate at least one pixel in said image frames;
- selecting at least one point of interest in a first of said image frames,
- calculating a first set of estimates of motion from the at least one point of interest;
- removing at least one outlier from said first set of estimates of motion to create a second set of estimates of motion;
- wherein the second set of estimates of motion is smaller in number than the first set of estimates of motion;
- and
- determining a global motion estimate from said second set of estimates of motion.

A device capable of:
- storing at least two consecutive frames of an image in at least one memory location on the device,
- downsampling to eliminate at least one pixel in said image frames;
- selecting at least one point of interest in a first of said image frames,
- calculating a first set of estimates of motion from the at least one point of interest;
- removing at least one outlier from said first set of estimates of motion to create a second set of estimates of motion;
- wherein the second set of estimates of motion is smaller in number than the first set of estimates of motion;
- and
- determining a global motion estimate from said second set of estimates of motion.

A non-transitory computer-readable information storage media having stored thereon instructions, that if executed by a processor, cause to be performed a method comprising:
- storing at least two consecutive frames of an image in at least one memory location,
- downsampling to eliminate at least one pixel in said image frames;
- selecting at least one point of interest in a first of said image frames,
- calculating a first set of estimates of motion from the at least one point of interest;
- removing at least one outlier from said first set of estimates of motion to create a second set of estimates of motion;
- wherein the second set of estimates of motion is smaller in number than the first set of estimates of motion;
- and
- determining a global motion estimate from said second set of estimates of motion.
