Abstract

Create image detail for an image. Images are processed to obtain image information. The detected texture samples are processed to obtain texture information. The processor device is used to transform the received image information for obtaining frequency domain information. Texture information is used to determine the boost factor. A boost factor is used to determine a frequency distribution for frequency domain information for use in creating a specific frequency. An inverse transform is performed on the updated frequency distribution for use in creating output image patches. The output image patches are combined to create image detail for the enhanced image. The enhanced image is blended with the image.

Description

technical field [0001] One or more embodiments relate generally to ultra-high definition (UD) displays and, in particular, to utilizing adaptive frequency upscaling to create detail in lower resolution images for display on a UD display or device. Background technique [0002] UD users, such as UD televisions (UDTV) or other UD display devices must watch lower resolution content (e.g., standard definition (SD), high definition (HD), full HD (FHD), etc. ) until UD video becomes more common. When viewing a lower resolution frame on a UD device, its image quality appears to be reduced. Conventional image upscaling or interpolation cannot provide sufficient image sharpness and fine details to minimize image quality degradation. Contents of the invention [0003] Technical solutions [0004] One or more embodiments relate to creating image details for images. In one embodiment, a method includes receiving input image information. In one embodiment, the processor device is ...
