Global Motion Estimation Image Coding And Processing

View page
US Patent:
7349583, Mar 25, 2008
Filed:
Sep 1, 2004
Appl. No.:
10/931473
Inventors:
Sanjeev Kumar - La Jolla CA, US
Truong Nguyen - San Diego CA, US
Mainak Biswas - La Jolla CA, US
Assignee:
The Regents of the University of California - Oakland CA
International Classification:
G06K 9/32
US Classification:
382294, 345648, 345649, 348583, 348699, 382107
Abstract:
The invention provides methods for global motion estimation, determining a coarse estimation, and refining a coarse estimation. Embodiments of the invention provide a fast and robust global motion estimation algorithm based on two-stage coarse-to-fine refinement strategy, which is capable of measuring large motions. An embodiment of the invention may be applied as a modification of any standard, e. g. MPEG-4 that uses the affine model of motion estimation. Embodiments of the invention may be used in the six parameter affine motion model, and other embodiments of the invention are applicable to the two parameter translation model, the four parameter RST model, and the eight parameter projective model. In a preferred embodiment, a coarse estimation is developed in a translation invariant domain, and then is refined in the spatial domain.

Video Encoding Methods And Devices

US Patent:
7623719, Nov 24, 2009
Filed:
Sep 23, 2004
Appl. No.:
10/948098
Inventors:
Andrea Molino - Torino, IT
Fabrizio Vacca - Rivarolo Canavese, IT
Mainak Biswas - La Jolla CA, US
Truong Nguyen - San Diego CA, US
Assignee:
The Regents of the University of California - Oakland CA
International Classification:
G06K 9/36
US Classification:
382239, 382240, 382248
Abstract:
A video codec of a preferred embodiment is suitable for implementation on a variety of platforms, including platforms where devices require both encoding and decoding engines. Various features of preferred embodiment codecs reduce complexity for operations such as motion determination. Channel resources are allocated in preferred embodiments unequally, with an allocation being determined based upon channel conditions and the error level in a frame being encoded. A decoder of a preferred embodiment, provided with an error frame and motion vector information may conduct decoding with motion compensation. In an example encoder of the invention, a motion estimator identifies motion vectors using a phase plane correlation technique based on phase quantization, where the phase difference between the Fourier transformed version of blocks in a reference frame and a current frame is estimated by dividing the complex plane into sectors and assigning the Fourier domain difference to the sectors.

US Patent:
8295607, Oct 23, 2012
Filed:
Jun 24, 2009
Appl. No.:
12/490639
Inventors:
Mainak Biswas - Santa Cruz CA, US
Vipin Namboodiri - Bangalore, IN
Assignee:
Marvell International Ltd. - Hamilton
International Classification:
G06K 9/48
G06K 9/62
G06K 9/38
G06K 9/46
G06K 9/66
US Classification:
382199, 382224, 382270, 382192, 382194
Abstract:
A method for detecting edges includes calculating a gradient level value for each pixel of a digital image and assigning each pixel to one of a plurality of gradient bins based on the calculated gradient level value for each pixel, the gradient bins being defined by threshold levels. One or more of the gradient bins are assigned as edge bins, and one or more of the gradient bins are assigned as non-edge bins according to the number of pixels assigned to each gradient bin. Pixels in the one or more edge bins are identified as edge pixels, and pixels in the one or more non-edge bins are identified as non-edge pixels in an edge map. The one or more gradient bins are assigned such that a minimum number of pixels are identified as edge pixels and no more than a maximum number of pixels are identified as edge pixels.

Jul 9, 2009
Appl. No.:
12/499932
Inventors:
Vipin Namboodiri - Bangalore, IN
Keepudi Muni Babu - Bangalore, IN
Mainak Biswas - Santa Cruz CA, US
Assignee:
Marvell International Ltd.
International Classification:
H04N 7/12
US Classification:
37524012
Abstract:
Systems, methods, and other embodiments associated with image frame management are described. According to one embodiment, an apparatus includes classifier logic to categorize frames that represent an image as either reference frames or non-reference frames, where the categorization is based, at least in part, on motion vectors between the frames. The apparatus further includes management logic to store the reference frames and to delete the non-reference frames. Image generation logic may then reproduce the image by using the stored reference frames.
