Patent number: 8976299Abstract: A method for determining a scene boundary location dividing a first scene and a second scene in an input video sequence. The scene boundary location is determined responsive to a merit function value, which is a function of the candidate scene boundary location. The merit function value for a particular candidate scene boundary location is determined by representing the dynamic scene content for the input video frames before and after candidate scene boundary using sparse combinations of a set of basis functions, wherein the sparse combinations of the basis functions are determined by finding a sparse vector of weighting coefficients for each of the basis functions. The weighting coefficients determined for each of the input video frames are combined to determine the merit function value. The candidate scene boundary providing the smallest merit function value is designated to be the scene boundary location.Type: GrantFiled: March 7, 2012Date of Patent: March 10, 2015Assignee: Intellectual Ventures Fund 83 LLCInventors: Mrityunjay Kumar, Abdolreza Abdolhosseini Moghadam, Alexander C.

Patent number: 8934725Abstract: Methods and apparatus for coding and/or decoding bitplanes are described. Aspects relate to speeding up bitplane coding when one or more entropy coders are used as part of the encoding process. A number, e.g., three, consistent value, e.g., zero value, bitplanes are identified and subjected to coding, e.g., in some embodiments using a JPEG 2000 arithmetic coder. Remaining bitplanes including data are subjected to coding using a second coding process, e.g., an entropy coding process implemented by a JPEG 2000 selective arithmetic bypass coder. By subjecting zero value bitplanes to the coding, e.g., arithmetic coder processing or its equivalent, 3 bitplanes are subjected to fast, easy to implement coding while non-consistent value bitplanes can be coded using selective arithmetic bypass coding. This satisfies the JPEG 2000 requirement that 3 bitplanes be generated in accordance with arithmetic coder processing while avoiding the normal delays associated with processing of non-consistent value bitplanes.Type: GrantFiled: October 12, 2010Date of Patent: January 13, 2015Assignee: Accusoft CorporationInventor: Thomas Richter

Patent number: 8934140Abstract: A color gamut of image data is appropriately subjected to a smoothing processing to print an image of favorable color reproduction and gradation reproduction. Specifically, when an average lightness is equal to or lower than a blacking lightness, the object pixel is not subjected to the smoothing processing. This can conserve the signal value of the object pixel to prevent a pixel originally having a signal value higher than the blacking lightness from being converted by the gamut compression to a black point. In this manner, a pixel for which the object pixel has the average lightness equal to or lower than the blacking lightness is blacked and a pixel having a signal value higher than the blacking lightness is not compressed to the black point. The resultant image has no deteriorated gradation characteristic when being macroscopically observed.Type: GrantFiled: March 27, 2008Date of Patent: January 13, 2015Assignee: Canon Kabushiki KaishaInventors: Ayumi Hori, Fumihiro Goto, Yusuke Hashii, Tetsuya Suwa, Fumitaka Goto

Patent number: 8929653Abstract: Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.Type: GrantFiled: September 23, 2013Date of Patent: January 6, 2015Assignee: Sony CorporationInventors: Ko Ishimoto, Koichiro Kakinuma, Takehiro Nakatsue, Tatsuhiko Matsumoto, Shuichi Haga, Hiroshi Takizuka, Yoshiki Shirochi, Naoya Katoh, Hiroshi Yamashita, Koichi Oura, Yoshihiro Kosugi, Junichi Iwai, Kazuji Uemura, Shigeo Kubota, Hideo Morita

Patent number: 8929632Abstract: A method of visualizing changes in blood flow in a digital subtraction angiography (DSA) image sequence is disclosed. A time-contrast curve is generated for all pixels in each image of the DSA image sequence. A reference parameter for each time-contrast curve to be used as a first time point is specified. The value of the reference parameter for each time-contrast curve is determined and an arbitrary parameter is specified for each time-contrast curve to be used as a second time point. An output image is generated by applying a color-coding of the difference between the first time point and the second time point to all pixels.Type: GrantFiled: September 18, 2012Date of Patent: January 6, 2015Assignee: Siemens AktiengesellschaftInventors: Tim Horz, Markus Kowarschik

Patent number: 8928941Abstract: An image processing apparatus prints an image without streaks on a medium. A receiving section receives base color image data and non-base color image data. A detecting section detects a boundary between a first area in which the base color image is printed and a second area which surrounds the first area and no image is printed therein. A correction section performs correction on the image data to generate one of a third area defined in a peripheral portion of the first area and a fourth area which is defined in a peripheral portion of the second area and is contiguous to the first area. A smaller amount of base color toner is consumed in the third and fourth area than in the first area. A printing section prints an image on a medium in accordance with the corrected base color image data and the non-base color image data.Type: GrantFiled: December 20, 2013Date of Patent: January 6, 2015Assignee: Oki Data CorporationInventor: Akimitsu Kawano
