Filed:

Jun 12, 2007

Appl. No.:

12/522726

Inventors:

Ju Guo - Los Angeles CA, US
Marco Antonio Vasquez - Los Angeles CA, US

Assignee:

Thomson Licensing - Boulogne-Billancourt

International Classification:

G06K 9/00

US Classification:

382252

Abstract:

A system and method of the present disclosure provides a block, or region, based error diffusion process for reducing artifacts in images. The system and method allows for the generation and the control of the spatial frequency of a masking signal, e. g. , noise, in a way that it can be easily passed through the compression process. The system and method provides for selecting a block size of pixels of the image, adding a masking signal to the image, determining a quantization error for at least one block in the image, and distributing the quantization error to neighboring blocks in the image to mask artifacts in the image. An output image is then encoded with a compression function.

US Classification:

707 10, 7071041, 707E17009, 707E17032

Abstract:

A system for collecting metadata in association with recorded content includes equipment configured to record and process content in the workflow. Metadata collection devices include devices incorporated in the equipment and/or devices configured to externally access the system. The metadata collection devices are configured to collect metadata and associate the metadata with the content at any point and any time in the workflow. The collected metadata can then be used to automate, facilitate and improve content processing in any part of the workflow.

Abstract:

A system and method for scaling images are provided. An upscaling algorithm or function is employed that increases the size of an image and then filters the upscaled image to remove aliasing artifacts. The system and method provides for acquiring an image of a first size, detecting the geometry of the image, scaling the image to a second size, and filtering the scaled image with at least one filter based on the detected geometry. During the filtering process, the edges of objects in the upscaled image are detected and different filter frequency responses are provided for the detected edges. Providing different filter frequency responses for the detected edges preserves more details for line images.
