A method of video quality evaluation includes obtaining, by the at least one processor, a reference area of a reference video and a degraded area of a degraded video, based on a matching area of the reference video and the degraded video, using homography estimation; correcting, by the at least one processor, at least one of the reference area and the degraded area; and measuring, by the at least one processor, video quality of the degraded video by comparing a difference between the reference area and the degraded area through a full reference scheme.

An automated network-based test system for set top box devices is disclosed. According to certain embodiments, the network-based testing system using Simple Network Management Protocol facilitates remote testing of thousands of set-top boxes, where groups of these set top boxes can be located in various locations that are remote from a main controller server that is running the tests remotely.

In order to enhance security of a parked vehicle, an image transmitting device to be mounted on a vehicle includes: a checking unit that checks, at a parking place of the vehicle, communicability with an external device outside of the vehicle, that is, whether an image can be transmitted from the parking place to the external device; a providing unit that provides notification information based on a result of the checking by the checking unit; a capturing unit that captures an image while the vehicle is parked; and a transmitting unit that transmits the image captured by the capturing unit to the external device.

A method and apparatus for evaluating video quality are disclosed. An apparatus for evaluating video quality according to an embodiment of the invention includes: an encoder unit that converts a first-resolution original video sequence into a second-resolution original video sequence and encodes the second-resolution original video sequence; decoder unit that generates a second-resolution decoded video sequence by decoding the encoded second-resolution video sequence and converts the second-resolution decoded video sequence into a first-resolution decoded video sequence by interpolating the second-resolution decoded video sequence to the first resolution; a video quality index calculator unit that calculates a first video quality index by comparing the first-resolution original video sequence with the first-resolution decoded video sequence and calculates a second video quality index by comparing the second-resolution original video sequence with the second-resolution decoded video sequence; and a video quality evaluator unit that calculates a final video quality index by using the first video quality index and the second video quality index.

In various embodiments, a quality trainer trains a model that computes a value for a perceptual video quality metric for encoded video content. During a pre-training phase, the quality trainer partitions baseline values for metrics that describe baseline encoded video content into partitions based on genre. The quality trainer then performs cross-validation operations on the partitions to optimize hyperparameters associated with the model. Subsequently, during a training phase, the quality trainer performs training operations on the model that includes the optimized hyperparameters based on the baseline values for the metrics to generate a trained model. The trained model accurately tracks the video quality for the baseline encoded video content. Further, because the cross-validation operations minimize any potential overfitting, the trained model accurately and consistently predicts perceived video quality for non-baseline encoded video content across a wide range of genres.

There are disclosed various methods, apparatuses and computer program products for testing a display. In some embodiments an image sensor captures a rendered image from the display to form a captured image, the image sensor having a second resolution greater than the first resolution. The captured image is analyzed to find difference of orientation of the rendered image with respect to an orientation of the image sensor. A rotated image is formed on the basis of the analyzed difference of orientation to obtain orientation for the rotated image to correspond with the orientation of the image sensor. The rotated image is resampled to form a resampled image having the first resolution.

A method of booting an electronic device, methods of operating and controlling an electronic device, an electronic device, a control terminal, and an electronic device control system. The method of booting the electronic device includes: displaying a first graphic code on a screen of the electronic device, each of the first graphic codes corresponding to a preset booting instruction; scanning, by a first control terminal, the first graphic code, and transmitting a booting request of the electronic device to a second control terminal according to the first graphic codes; generating, by the second control terminal, a booting command of the electronic device according to the booting request, and transmitting the booting command to the electronic device; determining, by the electronic device, a turning-on time length of the electronic device according to a matching result between the booting command and the preset booting instruction.

The present disclosure relates to a method of audio debugging for television and an electronic device. In the method, when it is required to receive the audio in an external media source, the audio is sampled in an audio sampling rate of the audio and a sampling result obtained is stored; when it is required to play the audio, the sampling result is obtained again from the storage area and played. By the solution provided the disclosure, the television receives and plays an audio in an audio sampling rate of the audio itself, thereby avoiding the appearance of noise in the audio and improving the audio quality.

During calibration, a wearable video headset displays a pattern on a partially transparent display positioned in a field of view of a user's eye. The user has a hand-held marker that includes a scaled version of the displayed pattern. The user moves the marker toward or away from the user's eye until the pattern on the marker appears to be the same size as the pattern on the display. When the sizes match, the headset measures a distance between a forward-facing camera and the hand-held marker. The headset uses the measured distance, and geometrical relationships, to determine the spacing between the user's eye and the display. Such calibration can ensure that the images displayed to the user mesh realistically with the surroundings, which remain partially visible through the partially transparent display of the video headset.
