Systems and methods for treating occlusions in 2-d to 3-d image conversion

Abstract: The present invention is directed to systems and methods for processing 2 -D to 3-D images. The system and method includes a procedure for optimizing occlusion and/or texturing by creating tolerances in which such texturing need not occur.

Image conversion process and apparatus

Abstract: A process for transferring images from a first frame system to a second frame system is described. A first sequence from the first frame system is determined so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Likewise, a second sequence from the second frame system is selected so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Each image frame for the newly constructed second frame system is built by combining at least two image frames from the first frame system in a proportion such that the central timing factors of the two image frames of the first frame system combine so as to correspond to the central timing factor for the image frame in the second frame system. In this manner, the images from the first frame system combine in a smooth fashion in the second frame system such that jitter, freezes and jumps are eliminated. This image transfer process may be used to transfer images between the following frame systems: NTSC TV; PAL TV; Film 16; Film 24; Film 60 (Showscan system); and Computer images.

Image processing system and image processing method

Abstract: This invention provides an image processing system and image processing method, which can acquire a document such as a paper document or the like as data of a format that allows easy re-use and re-edit processes. Image information is acquired by scanning a document, and its features are recognized. The image information is converted into character codes, vector data, or a predetermined image format in accordance with the recognized features. In this case, parameters used upon recognizing the features of the image information are variably set, and the operations of the character process, vectorization, and image conversion are controlled in accordance with the set parameters.

Method and system for storing error values for an image conversion process utilizing dynamic error diffusion

Abstract: A method and system implements a dynamic error diffusion process. A grey level value representing a pixel is received. An image segmentation circuit determines an image characteristic of the pixel being processed. A threshold circuit thresholds the grey level value (pixel) and generates an error value as a result of the threshold process. A portion of the error value is diffused to adjacent pixels on a next scanline. The distribution of this error value is dynamic in that different sets of weighting coefficients are used based the image characteristic of the processed pixel. One set of coefficients are utilized in processing a pixel having a first image characteristic, and a second set of coefficients are utilized in processing a pixel having a second image characteristic.
