  • Publication number: 20190146326
    Abstract: In a method of manufacturing a photo mask, a resist layer is formed over a mask blank, which includes a mask substrate, a phase shift layer disposed on the mask substrate and a light blocking layer disposed on the phase shift layer. A resist pattern is formed by using a lithographic operation. The light blocking layer is patterned by using the resist pattern as an etching mask. The phase shift layer is patterned by using the patterned light blocking layer as an etching mask. A border region of the mask substrate is covered with an etching hard cover, while a pattern region of the mask substrate is opened. The patterned light blocking layer in the pattern region is patterned through the opening of the etching hard cover. A photo-etching operation is performed on the pattern region to remove residues of the light blocking layer.

  • Patent number: 7020345
    Abstract: The present invention relates to methods and systems for an illuminant compensation. In particular, these methods and systems include a method for operations on an image, for example, an image of a human face. In the described methods and systems, it is determined for each pixel in the image whether it is part of the face region. A surface fitting is then determined based on only the pixels that are determined to be part of the face region. Also, described are methods and systems for image normalization wherein the standard deviation and average for the gray levels of the pixels are determined and then used to normalize the image so that the gray level for each of the pixels falls between a particular range.

  • Patent number: 6798923
    Abstract: A method and system of merging a pair of images to form a seamless panoramic image including the following steps. A set of feature points are extracted along the edges of the images, each feature point defining an edge orientation. A set of registration parameters is obtained by determining an initial set of feature points from a first one of the images which matches a set of feature points of a second one of the images. A seamless panoramic image is rendered using the first and second images with the set of registration parameters.

  • Patent number: 6606623
    Abstract: An apparatus and method of content-based image retrieval generate a plurality of training images, including a first part and a second part. Each training image of the first part is labeled as one of a positive bag or a negative bag. The training image is labeled a positive bag if the training image has a desirable character and labeled a negative bag if the training image does not have a desirable character. A set of N1 training images is identified from a set of all training images of the second part, which identified images have a feature most closely matching a first feature instance of a training image labeled as a positive bag. A first value corresponding to the first feature instance is calculated, based on the number of images labeled as positive bags that are identified in the set of N1 training images.

  • Patent number: 6477268
    Abstract: A method is described for producing smooth transitions between a source vista and a destination vista with unknown camera axes in panoramic image based virtual environments. The epipoles on the source vista and the destination vista are determined to align the vistas. Corresponding control lines are selected in the vistas to compute the image flow between the vistas and to densely match the pixels. In-between image frames are computed by forward-resampling the source vista and backward-resampling the destination vista.

  • Patent number: 6011558
    Abstract: A pair of images are stitched together by warping the pair of images into an environment map representative of a panoramic image. A first edge and a corresponding second edge for each of the first and second images, respectively, are detected. A set of edge position coordinates along the edge of the first warped image is determined. A set of possible matched solutions from the edge position coordinates of the first and second edge are generated. An optimum matched offset from the set of possible matched solutions is determined. Because the set of possible matched solutions is small and compact, the optimum matched offset can be determined efficiently from the set of solutions.

  • Patent number: 5909509
    Abstract: A character recognition device and system:(1) constructs a database comprising pairs of similar-looking characters;(2) selects critical features distinguishing these characters from each other; and(3) performs a recognition process based on the selected critical features.In the present invention, sample data is automatically analyzed to construct a feature reference database for a typical character recognition device. If two characters are confused for a threshold number of times, this pair is considered to be similar-looking or confusing. The reference data already accumulated is statistically analyzed for each similar-looking pair to determine the importance of certain features in distinguishing the two characters. These features are further statistically analyzed so that only the most dominant features will be looked at and the less dominant or similar-looking features will be ignored.
