Abstract

In some embodiments, a method receives an image to analyze for artifacts. Texture information that characterizes texture in the image is determined. The method merges the texture information with the image. The texture information is used to focus an analysis of artifacts in regions of the image. The method outputs a score based on the processing of the image that assesses the artifacts in the image.

Background

BACKGROUND

Artifacts in digital video may be distortions that appear in the video. Different types of artifacts may occur. For example, one artifact is banding, which may be where a continuous change of luminance and chrominance becomes a sudden drop in values creating visible bands that should not be present in the video. The banding artifact may occur when the available bit depth for presenting the luminance or chrominance information is limited. That is, having 8 bits to represent the luminance and chrominance information may result in more visible bands compared to having more bit depth, such as 10 or 12 bits, to represent the luminance and chrominance information. Other artifacts may also result in video for different reasons.

A video delivery system may want to mitigate the occurrence of the artifacts that may occur in a video. However, it may be challenging to identify and measure the artifacts, and then later mitigate the artifacts.

Claims

1. A method comprising: receiving an image to analyze for artifacts; determining texture information that characterizes texture in the image; merging the texture information with the image, wherein the texture information is used to focus an analysis of artifacts in regions of the image; and outputting a score based on the processing of the image that assesses the artifacts in the image. || 17. A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for: receiving an image to analyze for artifacts; determining texture information that characterizes texture in the image; merging the texture information with the image, wherein the texture information is used to focus an analysis of artifacts in regions of the image; and outputting a score based on the processing of the image that assesses the artifacts in the image. || 20. An apparatus comprising: one or more computer processors; and a computer-readable storage medium comprising instructions for controlling the one or more computer processors to be operable for: receiving an image to analyze for artifacts; determining texture information that characterizes texture in the image; merging the texture information with the image, wherein the texture information is used to focus an analysis of artifacts in regions of the image; and outputting a score based on the processing of the image that assesses the artifacts in the image.
