摘要： A video stabilization method. First, optical flows between successive frames are calculated. The camera motion is then estimated by fitting the computed optical flow field to a simplified affine motion model with a trimmed least square method. Then, the computed camera motions are smoothed to reduce the motion vibrations by using a regularization method. Finally, all frames of the video are transformed based on the original and smoothed motions to obtain a stabilized video.

摘要： The present invention is related to a digital image-processing method for conducting a color gradient, which includes the steps of: (a) constructing a draft enclosed by an inner closed curve and an outer closed curve; (b) dividing the draft into a plurality of regions, each of which is enclosed by the inner closed curve, the outer closed curve, and two control lines constructed by respectively connecting a reference point located within an inner area defined by the inner closed curve with two control points located on the outer closed curve, wherein the plurality of regions are integrated to form the draft; and (c) introducing an operation to bring about a color gradient effect in each of the plurality of regions. By utilizing the present digital image-processing method to conduct a color gradient on a draft to form a color palette, no color gap will be observed.
