Abstract: Approaches in accordance with various illustrative embodiments provide for the determination and/or optimization the quality of an image or video, such as an image that has been compressed for transmission or storage then decompressed for presentation. Weights can be determined for a set of weight-based quality metrics to produce an overall quality metric that is a weighted combination of these metrics. Because different portions of an image or video frame may have different types of features, an image or video frame can be divided into blocks of pixels, for example, with different weights being assigned to different blocks using quality metrics. Different metrics can be considered as points in a high-dimensional weight space, with each dimension corresponding to a weight of a block. A combination of these points results in an improved quality metric. Compression settings can be updated based in part upon the overall quality metric values.

Abstract: Systems and methods herein are for a video encoder to be associated with an interface that is to receive, from an application, at least one metric that is associated with a quality preference for video compression to be performed by the video encoder and that is to provide a weight map to enable the video encoder to perform rate-distortion optimization (RDO) for received frames from the application using the weight map to weigh one or more first blocks associated with an individual one of the frames more than one or more second blocks associated with the individual one of the frames.
