Three-dimensional perspective correction
Embodiments of the present disclosure set forth techniques for three-dimensional perspective correction, where the techniques include receiving a first image that depicts an object from a first perspective along a first axis; determining a location of the object along the first axis; determining, based on the first image and the location of the object along the first axis, at least one dimension of the object; and adjusting, based on the at least one dimension of the object, a second image that depicts the object from a second perspective along a second axis. In some embodiments, adjusting the second image comprises skewing at least a portion of the second image to depict the object from a third perspective along a third axis.
