Method And Apparatus For Sharpening An Image By Scaling Elements Of A Frequency-Domain Representation

View page
US Patent:
6421468, Jul 16, 2002
Filed:
Jan 6, 1999
Appl. No.:
09/226370
Inventors:
Viresh Ratnakar - Sunnyvale CA
Vasudev Bhaskaran - Mountain View CA
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
H04N 712
US Classification:
382254, 382191
Abstract:
An original image is sharpened by obtaining a first frequency-domain representation of the original image, selecting one or more elements from this first representation based on one more criteria such as element magnitude and frequency, scaling the selected elements according to one or more scale factors, and forming a second frequency-domain representation by combining the scaled selected elements with the unselected elements of the first representation. A sharpened reproduction of the original image may be generated by applying an inverse transform to the second frequency-domain representation. A technique for deriving the value of the one or more scale factors is also discussed.

Multiplier-Free Implementation Of Dct Used In Image And Video Processing And Compression

View page
US Patent:
6473534, Oct 29, 2002
Filed:
Jan 6, 1999
Appl. No.:
09/226584
Inventors:
Neri Merhav - Haifa, IL
Vasudev Bhaskaran - Mountain View CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
G06K 936
US Classification:
382250, 36472503, 382251
Abstract:
Multiplier-free implementation of an approximation of the DCT used in image and video processing. In accordance with the primary aspect of the present invention, image and video processing is done with no multiplications and a fewer number of operations through the application of a modified Arai, Agui, and Nakajima (AAN) scheme for eight-point DCT.

Fast Compressed Domain Processing Using Orthogonality

View page
US Patent:
6490323, Dec 3, 2002
Filed:
Jun 17, 1999
Appl. No.:
09/335464
Inventors:
Bo Shen - Mountain View CA
Vasudev Bhaskaran - Palo Alto CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H04N 712
US Classification:
3752402
Abstract:
A method and apparatus for receiving and processing digitized video data in a discrete cosine transform (DCT) domain exploits the orthogonality of a convolution function along with the data sparseness present in the DCT domain. In a preferred method, the convolution function is applied to vectors associated with a plurality of input video data frames in consideration of an orthogonal characteristic of the convolution function. More specifically, cross-products of the input vectors which would yield non-zero output vectors are identified and weighting factors for the cross-products are determined in consideration of this orthogonality. An output video data frame is generated from the non-zero output vectors and the weighting factors. A convolution operation based upon the disclosed method and aparatus is suitable for chroma-keying as well as other video or audio blending applications.

Hybrid Technique For Reducing Blocking And Ringing Artifacts In Low-Bit-Rate Coding

View page
US Patent:
6950473, Sep 27, 2005
Filed:
Jun 21, 2002
Appl. No.:
10/176994
Inventors:
Changick Kim - Cupertino CA, US
William Chen - Foster City CA, US
Vasudev Bhaskaran - Mountain View CA, US
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
H04N007/12
US Classification:
37524029
Abstract:
A power-scalable hybrid technique to reduce blocking and ringing artifacts in low bit-rate block-based video coding is employed in connection with a modified decoder structure. Fast inverse motion compensation is applied directly in the compressed domain, so that the transform (e. g. , DCT) coefficients of the current frame can be reconstructed from those of the previous frame. The spatial characteristics of each block is calculated from the DCT coefficients, and each block is classified as either low-activity or high-activity. For each low-activity block, its DC coefficient value and the DC coefficient values of the surrounding eight neighbor blocks are exploited to predict low frequency AC coefficients which reflect the original coefficients before quantization in the encoding stage. The predicted AC coefficients are inserted into the low activity blocks where blocking artifacts are most noticeable. Subject to available resources, this may be followed by spatial domain post-processing, in which two kinds of low-pass filters are adaptively applied, on a block-by-block basis, according to the classification of the particular block.

Image Scaling In The Compressed Domain

View page
US Patent:
7050656, May 23, 2006
Filed:
Dec 11, 2002
Appl. No.:
10/316362
Inventors:
Vasudev Bhaskaran - Sunnyvale CA, US
Viresh Ratnakar - Sunnyvale CA, US
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
G06K 9/32
US Classification:
382298, 382232, 382240, 382250, 382251
Abstract:
An efficient compressed-domain-based algorithm that works by combining the IDCT and pixel-domain averaging into a single compressed domain operation, where a part of the cost of even this simplified operation can be absorbed into the de-quantization process. The original image need not be decompressed fully, only to the point of extracting the transform coefficients. Compressed-domain scaling for all scales k/8 for 1≦k≦8, including ⅜, ⅝, , ⅞, is provided. By chaining multiple operations, any scale factors of the form kk. . . k/8for integers k's in the range [1,7] can be achieved.

Method And Apparatus For Transform Domain Video Processing

View page
US Patent:
7190724, Mar 13, 2007
Filed:
Dec 13, 2002
Appl. No.:
10/319775
Inventors:
William Chen - Foster City CA, US
Vasudev Bhaskaran - Sunnyvale CA, US
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
H04B 1/66
US Classification:
3752402
Abstract:
A method for reducing the memory requirements for decoding a bit stream is provided. The method initiates with receiving a video bit stream. Then, a frame of the bit stream is decoded into a transform domain representation. Next, non-zero coefficients of the transform domain representation are identified. Then, a hybrid data structure is assembled. The hybrid data structure includes a fixed size array and a variable size overflow vector. Next, the non-zero coefficients of the transform domain representation are inserted into the hybrid data structure. A computer readable media, a printed circuit board and a device configured to decode video data are also provided.

Method And Apparatus For Dct Domain Filtering For Block Based Encoding

View page
US Patent:
7212571, May 1, 2007
Filed:
Jan 31, 2003
Appl. No.:
10/355469
Inventors:
Vasudev Bhaskaran - Sunnyvale CA, US
Changick Kim - Cupertino CA, US
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
H04N 7/18
US Classification:
37524003, 37524005
Abstract:
A method for encoding video data to reduce blocking artifacts is provided. The method initiates with identifying a macro-block as being associated with a blocking artifact. For example the macro-block may be identified as a low activity macro-block or a high activity macro-block. Then, blocking artifacts introduced through a compression operation are mitigated by adjusting both a quantization parameter and an amount of bits generated from the quantization parameter. A video encoder and a system for processing image data associated with block based compression are provided.

Lape: Layered Presentation System Utilizing Compressed-Domain Image Processing

View page
US Patent:
7391910, Jun 24, 2008
Filed:
Jul 31, 2003
Appl. No.:
10/631072
Inventors:
Viresh Ratnakar - Sunnyvale CA, US
Vasudev Bhaskaran - Sunnyvale CA, US
Assignee:
Seiko Epson Corporation - Tokyo
International Classification:
G06K 9/36
G09G 5/00
G06K 9/46
US Classification:
382232, 345629
Abstract:
A layered presentation system (LAPE) includes a server that performs compressed-domain image processing on image data received from multiple clients including a master client and other clients to generate a composite image that incorporates imagery from the other clients with a master image from the master client for viewing on a shared display. The system's clients can add imagery in the form of questions, comments, and graphics to a currently displayed image. The added imagery is processed along with the master image to generate the composite image that then appears on the shared display and perhaps also on each client's individual display. The processing includes scaling the master image/added imagery, as required, and blending and/or overlaying the added imagery onto the master image so as to augment but not obscure it. A network protocol is included for sending image data in the compressed domain back and forth between the server and each of the clients.
