20130162629 | METHOD FOR GENERATING DEPTH MAPS FROM MONOCULAR IMAGES AND SYSTEMS USING THE SAME - Methods for generating depth maps from monocular still image or monocular video and systems using the same are provided. First, an initial depth map is estimated or arbitrary defined. For video inputs, motion information can be used, for still image the initial background can be arbitrary set by default, chosen by the user or can be estimated. Estimation of the initial depth map can be based on a contrast map or a blur map. The initial depth map defines initial depth values for the respective pixels of the monocular image or monocular motion picture frames. The respective pixels of the original image or video frame data are mapped to the initial depth map according to positions of the pixels, in order to obtain corresponding initial depth values. An image data space of the image is subdivided into a plurality of sub-image spaces, and the initial depth value of each of the pixels of the image is filtered according to the initial depth values of the pixels located in the same sub-image space, in order to obtain depth information for the pixels. | 06-27-2013 |

20130259315 | METHODS FOR GENERATING STEREOSCOPIC VIEWS FROM MONOSCOPIC ENDOSCOPE IMAGES AND SYSTEMS USING THE SAME - Methods for generating stereoscopic views from monoscopic endoscope images and systems using the same are provided. First, monoscopic images are obtained by capturing images of organs in an operating field via an endoscope. A back-ground depth map of the operating field is obtained for each image. An instrument depth map corresponding to an instrument is obtained for each image, wherein the instrument is inserted in a patient's body cavity. The background depth maps and the instrument depth maps are merged to generate an integrated depth map for each image. Stereoscopic views are generated according to the monoscopic images and the integrated depth maps. | 10-03-2013 |
