Patent number: 8928804Abstract: Disclosed are various embodiments directed to transcoding a bit stream in parallel. A bit stream may be divided into a plurality of segments, where a plurality of transcoders encode at least a portion of the segments in parallel.

Patent number: 8923653Abstract: Super-resolution processing is regarded as a kind of intersample interpolation process and performed by using a linear interpolation filter designed according to sampled-data control theory. In an error-system model used in the process of designing the filter, a pre-filter is disposed before a sampler and a post-filter is disposed after the zero-order hold in a signal restoration system. At least either one of the characteristic Q(s) of the pre-filter or the characteristic P(s) of the post-filter is designed to be a low-pass characteristic, whereby the gain of the characteristic K(z) of a digital filter within a middle-to-high frequency range is raised. Raising the gain makes jaggies more prominent. To reduce this effect, in an actual processing system, the image to be processed is passed through a low-pass filter to reduce high-frequency components before the linear interpolation is performed.Type: GrantFiled: February 3, 2012Date of Patent: December 30, 2014Inventors: Yutaka Yamamoto, Kengo Zenitani

Patent number: 8891903Abstract: A method for scaling two-dimensional structures, which is especially usable for resizing digital 2D images with a rational scaling factor, is based on efficient implementation of a diamond-shaped filter. The conventional “1”-diamond matrices of variable size are replaced by a (m×n) coefficient matrix. For any given rational scaling factor, the computational load for calculating an output pixel is reduced to filtering (m×n) input pixels with a corresponding (m×n) filter matrix. The coefficients of this filter matrix depend from the phase of the output pixel to be calculated and the factor of interpolation, but are always integer numbers. The coefficients may be stored in lookup tables (LUT), which leads to a very efficient implementation of the inventive method. In one embodiment, a (3×3) coefficient matrix has been found to be advantageous.Type: GrantFiled: July 5, 2012Date of Patent: November 18, 2014Assignee: Brandenburgische Technische Universität Cottbus-SenftenbergInventors: Stefan Schiemenz, Christian Hentschel

Publication number: 20140301663Abstract: Disclosed are various embodiments for systems and methods for image processing. A resizing template may be generated having one or more image sizes of an original image based at least in part on resize settings. A preview may then be generated of preview images of the original image based at least in part on the resizing template and the resize settings. The resize settings may be further adjusted via the preview. Upon approval of the preview and the adjusted resize settings, the original image is processed to generate final resized images according to the template and the modified resize settings.Type: ApplicationFiled: April 1, 2014Publication date: October 9, 2014Inventors: Eric Livingston, Carrie Thorpe, Mark Stewart

Patent number: 8855444Abstract: Method for partitioning a digital image into two or more regions where each region is defined using a portion of the digital image. In addition, margin pixels for each region are defined as pixels that correspond to a top margin, a bottom margin, a left margin, and a right margin of each region of the digital image. Margin pixels are generated by using various techniques such as on-the-fly generation, using data information of neighboring pixels to each region, using data information of pixels within each region, or using predetermined data information for a color including black. The pixels of each region are processed with its margin pixels to create a new processed region of the digital image. The processing may include scaling of each region from a first resolution to a second resolution. The data information of each processed region can be displayed using a portion of an electronic display panel, or a monitor having with multiple display regions.Type: GrantFiled: December 22, 2012Date of Patent: October 7, 2014Assignee: Marseille Networks, Inc.Inventor: Emmanuel Hislen

Patent number: 8855431Abstract: Method and apparatus for compressed sensing yields acceptable quality reconstructions of an object from reduced numbers of measurements. A component x of a signal or image is represented as a vector having m entries. Measurements y, comprising a vector with n entries, where n is less than m, are made. An approximate reconstruction of the m-vector x is made from y. Special measurement matrices allow measurements y=Ax+z, where y is the measured m-vector, x the desired n-vector and z an m-vector representing noise. “A” is an n by m matrix, i.e. an array with fewer rows than columns. “A” enables delivery of an approximate reconstruction, x#? of x. An embodiment discloses approximate reconstruction of x from the reduced-dimensionality measurement y. Given y, and the matrix A, approximate reconstruction x# of x is possible. This embodiment is driven by the goal of promoting the approximate sparsity of x#.Type: GrantFiled: December 12, 2011Date of Patent: October 7, 2014Inventor: David Leigh Donoho

Patent number: 8855445Abstract: An image processing apparatus includes: an acquisition unit configured to acquire original image data expressing an original image that comprises a first type pixel and a second type pixel; and an enlargement processing unit configured to execute enlargement processing for the original image data to generate enlarged image data expressing an enlarged image that is obtained by enlarging the original image in a first direction. The enlargement processing unit includes: a pixel group selection unit configured to select a pixel group extending in a second direction intersecting with the first direction in the enlarge image when a specific pattern configured by the first type pixel and the second type pixel is included in the original image; and a setting unit configured to set a pixel configuring the pixel group in the enlarged image as the second type pixel.Type: GrantFiled: February 11, 2013Date of Patent: October 7, 2014Assignee: Brother Kogyo Kabushiki KaishaInventor: Ryuji Yamada

Patent number: 8855443Abstract: To detect non-uniform spatial scaling of an image in the horizontal direction (for example in 4:3 to 16:9 aspect ratio conversion) the image is divided into regions, for example a middle region and two side regions. A measure of horizontal spatial frequency energy is taken in each region by for example subtracting the values of horizontally adjacent pixels and a comparison is made between measures of horizontal spatial frequency energy for the different regions.Type: GrantFiled: May 24, 2010Date of Patent: October 7, 2014Assignee: Snell LimitedInventor: Michael James Knee

Patent number: 8849067Abstract: According to an embodiment, an image processing apparatus includes: a reading unit, a magnification change processing unit, a wait time acquiring unit, and a signal output unit. The reading unit reads image data from the memory line by line. The magnification change processing unit performs a magnification change process on the image data and outputs. The wait time acquiring unit acquires wait time information on a value corresponding to a wait time from when a synchronous signal, representing a start of read of the image data for each line, falls to when the magnification change process starts. The signal output unit outputs, to the reading unit, a permission signal indicating whether read of image data of a next line is permitted or denied based on the wait time information while the magnification change processing unit is outputting the image data.Type: GrantFiled: August 10, 2012Date of Patent: September 30, 2014Assignee: Ricoh Company, LimitedInventor: Fumihiro Sasaki

Patent number: 8842937Abstract: Methods for reducing dimensionality of hyperspectral image data having a number of spatial pixels, each associated with a number of spectral dimensions, include receiving sets of coefficients associated with each pixel of the hyperspectral image data, a set of basis vectors utilized to generate the sets of coefficients, and either a maximum error value or a maximum data size. The methods also include calculating, using a processor, a first set of errors for each pixel associated with the set of basis vectors, and one or more additional sets of errors for each pixel associated with one or more subsets of the set of basis vectors. Utilizing such errors calculations, an optimum size of the set of basis vectors may be ascertained, allowing for either a minimum amount of error within the maximum data size, or a minimum data size within the maximum error value.Type: GrantFiled: November 22, 2011Date of Patent: September 23, 2014Assignee: Raytheon CompanyInventors: Ian S.
