Abstract
Official abstract text for this publication.
A method includes generating, by a processor, a label map by labeling pixels in an image. A percentage of a first and second type of texture pixels is determined based on the label map to generate a texture map. The texture map is updated. A directional edge map is generated based on a data correlation analysis based on the texture map and the label map. A gain map with boundaries and smoothing is generated using localized pixels based on information from one or more of the label map, the texture map, and the directional edge map. An enhancement controlled upscaled image frame is generated using one or more of the label map, the texture map, the directional edge map and the gain map as a weight factor.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: generating, by a processor, a label map by labeling pixels in an image frame based on a closest color cluster center to the pixels; determining a percentage of a first type of texture pixels and a percentage of a second type of texture pixels based on the label map to generate a texture map of the image frame; updating the texture map by updating texture probability as a local average with an updating factor for a particular differen…
