[−][src]Module av_metrics::video
Contains metrics related to video/image quality.
Modules
| ciede | The CIEDE2000 color difference formula. |
| psnr | Peak Signal-to-Noise Ratio metric. |
| psnr_hvs | Peak Signal-to-Noise Ratio metric accounting for the Human Visual System. |
| ssim | Structural Similarity index. |
Structs
| FrameInfo | A container holding the data for one video frame. This includes all planes of the video. Currently, only YUV/YCbCr format is supported. Bit depths up to 16-bit are supported. |
| PlanarMetrics | Certain metrics return a value per plane. This struct contains the output for those metrics per plane, as well as a weighted average of the planes. |
| PlaneData | Contains the data for one plane in a video frame. For chroma planes, this data is represented in the original chroma sampling. E.g. if this is a 4:2:0 video clip, the chroma planes will have half the resolution, in each dimension, of the luma plane. |
Enums
| ChromaSamplePosition | Sample position for subsampled chroma |
| ChromaSampling | Available chroma sampling formats. |
Traits
| CastFromPrimitive | Defines a type which supports being cast to from a generic integer type. |
| Decoder | A trait for allowing metrics to decode generic video formats. |
| Pixel | A trait for types which may represent a pixel in a video.
