    摘要: The invention is made in the technical field of video quality measurement. More precisely, the invention is related to mean observer score prediction using a trained semi-supervised learning regressor. That is, a method and apparatus for measuring video quality using a semi-supervised learning system for mean observer score prediction is proposed. Said semi-supervised learning system comprises at least one semi-supervised learning regressor and said method comprises training the learning system and retraining the trained learning system using a selection of test data wherein the test data is used for determining at least one mean observer score prediction using the trained learning system and the selection is indicated by a feedback received through a user interface upon presenting, in the user interface, said at least one mean observer score prediction. Doing so, prediction quality can be improved after re-training at least for the selection.

    摘要: The purpose of an objective video quality evaluation is to automatically assess the quality of video sequences in agreement with human quality perception. The invention addresses the effects of the introduction of a temporal dimension by focusing on the temporal evolutions of spatial distortions, since it has been found that a spatial quality variation cannot be evaluated by simple subtraction of the spatial quality of neighboring frames. An improved method for estimating perceived video quality comprises steps of calculating a first similarity map between adjacent frames of a current sequence, calculating a second similarity map between the corresponding reference frames, and calculating (smg3) a third similarity map, which provides a numerical quality value.

    摘要: A control circuit for an indicator light includes a power source, a switch unit, a ground resistor, and a first adjusting unit. The power source supplies a voltage. The switch unit is connected between the power source and the indicator light and turns on or turns off the indicator light. The ground resistor is connected between the power source and the ground via the indicator light and the switch unit. The first adjusting unit includes a first adjusting resistor and a first control switch. The adjusting resistor is connected between the indicator light and the ground via the first control switch. The first control switch is capable of connecting the first adjusting resistor with the ground resistor in parallel.
