What's new in VQ Probe v3.4

Ability to offload metrics calculation to Intel(R) GPUs

We have added a new calculation mode that allows users to offload metrics calculation to Intel(R) GPUs.

New metric: XPSNR

We have added a new metric to VQ Probe: XPSNR. Output values of this metric are in a similar range as those of traditional PSNR assessments but better reflect human impressions of visual coding quality.

PNG support

We have also added support for PNG images in VQ Probe.

Ability to disable metrics calculation for any stream

You can now disable metrics calculation for any stream by unchecking the Metrics checkbox.

Ability to calculate BD Rate for the Convex Hull curve

BD Rate is now calculated for the Convex Hull curve.

Ability to add found objects to the list of ROIs

We have added the ability to add a found object to the current project as a region of interest (ROI). Click the Add to ROI List button to add the selected object.

Ability to trim streams by scene

We have also added the ability to use scenes found by our Scene Change Detection algorithm to trim streams. Press Set Start/End to this scene to trim streams to a chosen scene.
