Determines the multi-scale structural similarity (MSSSIM) of two images with identical frame type for images with pixel formats that have 8 bit per channel.
Beware: For backwards-compatibility the implementation of this function does not fully match that in the paper "Multi-Scale Structural Similarity for Image Quality Assessment"
- Parameters
-
| imageX | The first image to be used, must be valid |
| imageY | The second image to be used, must be valid |
| width | The width of both images in pixel, with range [11, infinity) |
| height | The height of both images in pixel, with range [11, infinity) |
| channels | The number of data channels both images have, with range [1, 4] |
| imageXPaddingElements | Optional number of padding elements at the end of each first image row, in elements, with range [0, infinity) |
| imageYPaddingElements | Optional number of padding elements at the end of each second image row, in elements, with range [0, infinity) |
| msssim | The resulting msssim index, with range [0, 1] |
| worker | Optional worker object to distribute the computation |
