Methods and apparatuses for upscaling video

摘要

In one embodiment, the methods and apparatuses detect content that represents original image information; detect a direction of the content wherein the direction corresponds to a portion of the original image information; compare a variation between adjacent pixels that are represented by the original image information; and generate new image information based on the direction of the content and the variation between the adjacent pixels.

主权项

1. A method comprising:
detecting content that represents original image information; detecting a direction of a portion of the original image information; computing local orientation on a plurality of scales amongst neighboring pixels that are represented by the original image information by varying a scale of each neighborhood being considered, wherein local orientation is computed by calculations involving covariance of image attributes in neighboring pixels; combining the plurality of scales of computed local orientations to determine a degree of variation amongst adjacent pixels, wherein the variation is determined by a similarity or dissimilarity of the plurality of scales of computed local orientations; and generating new image information based on the detected direction and the degree of variation amongst the adjacent pixels in order to deinterlace or upscale the original image information.
