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.

The present invention discloses a data scanning system and a method thereof for a server. The method includes steps of defining an auditing period, scanning an accessed data in a default scanning mode from the server by a user, obtaining a credit data of the user, and executing a rearranging process for resetting a reset scanning mode for the user according to the credit data when the auditing period is expired, thereby the default scanning mode being adjustable according to the credit data of the user.

A system and method for creating a three-dimensional graphic object is disclosed. The system comprises an outline-processing unit for modeling a first two-dimensional object by at least one outline, a curve-processing unit for modeling a second two-dimensional object by a closed curve, a curve-adjusting unit for adjusting the closed curve in response to the outline so as to generate a third two-dimensional object, a uniting unit for uniting the first and third two-dimensional objects to generate a-fourth two-dimensional object modeled by the adjusted closed curve and the at least one outline, a 3-D creating unit for generating the first, third and fourth two-dimensional objects three-dimensional to form a first three-dimensional object, a second three-dimensional object and a third three-dimensional object, respectively, and a graphics-combining unit for grouping two of the first, second and third three-dimensional objects for creating the three-dimensional graphic object in response to either a convex or a concave mode selection.

A image processing unit, and particularly to a one-button-triggered image processing unit capable of processing image data automatically. This one-button-triggered image processing unit comprises a button for inputting a trigger signal so as to start on the operation of the unit; a prescan module for prescanning a target at a first resolution; a target image calculation module for calculating the first image area; a target image marking module for marking out the target image contour in the first image; a scan module for scanning the target at the second resolution assigned by a user; a target image processing module for filtering impurities and straightening on the target image of the second image area; and a crop module for abstracting the target image by the marked contour in the second image and trimming the edge of the abstracted target image to get a target the same size as the scanned target.

A method for an image-based rendering of light in a virtual volume is disclosed, which can provide various lighting effects in the two-dimensional image of a three-dimensional object. Furthermore, the virtual light source can be located at any position corresponding to the three-dimensional object. The light sources in the image are divided into two groups, i.e., the light sources in the rear of the three-dimensional object and the light sources in the front of the three-dimensional object. Then, each image for the illuminating effects of the light sources in the rear of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the rear of the three-dimensional object is merged with the image of the three-dimensional object. Thereafter, each image for the illuminating effects of the light sources in the front of the three-dimensional object is merged in sequence. The merged image of all of the light sources in the front of the three-dimensional object is provided with various effects by calculation with special functions. The merged image having various effects is finally merged into the merged image of the image for the illuminating effects of the light sources in the rear of the three-dimensional object and the image of the three-dimensional object to accomplish the image-based rendering of light for the three-dimensional object.

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.
