Abstract: A low-complexity method of converting 2D images/videos into 3D ones includes the steps of identifying whether each pixel in one of the frames is an edge feature point; locating at least two vanishing lines in the frame according to the edge feature point; categorizing the frame into the one of close-up photographic feature, of landscape feature, and of vanishing-area feature; if the frame is identified to have the vanishing-area feature or the landscape feature to generate a GDM; and apply a modificatory procedure to the GDM to generate a final depth information map; if the frame is identified to have the close-up photographic feature, distinguish between a foreground object and a background information in the frame and define the depth of field to generate the final depth information map.

Abstract: A low-complexity panoramic image and video stitching method includes the steps of (1) providing a first image/video and a second image/video; (2) carrying out an image/video alignment to locate a plurality of common features from the first and second images/videos and to align the first and second images/videos pursuant to the common features; (3) carrying out an image/video projection and warping to make the first and second coordinates of the common features in the first and second images/videos correspond to each other and to stitch the first and second images/videos according to the mutually corresponsive first and second coordinates; (4) carrying out an image/video repairing and blending for compensating chromatic aberrations of at least one seam between the first and second images/videos; and outputting the stitched first and second images/videos.
