1. A method for selecting frames of an image sequence for panoramic stitching that is performed by a hardware processor, comprising:

  • for at least some chosen frames of the image sequence, the hardware processor executes software code that performs actions, including;

    evaluating frame overlap constraints between a current chosen frame and a previous chosen frame;

    evaluating frame motion constraints between the current and previous chosen frames, wherein the evaluation includes generating a histogram comprising a plurality of motion vectors for the current chosen frame with respect to the previous chosen frame;

    selectively saving the current chosen frame as being a qualifying frame if the frame overlap constraints and the frame motion constraints are met, wherein a motion vector corresponding to the largest bin the in the histogram is employed in determining if the frame overlap constraints and the frame motion constraints are met; and

    outputting the qualifying frames.
