Abstract

In today's network management world, there are various solutions that collect data and presume to identify events impacting the QoE of the end-users. However, such solutions usually do not try to address the question of whether the end-users are actually impacted. These solutions usually look at certain types of known problems and try to detect if that problem exists in the end-user's network, and from that they conclude that the end-user might be impacted. The method according to an embodiment of the invention enables to proactively identify that an end-user is actually experiencing an event impacting the QoE in his home network. The proposed solution enables the detection of event affecting an end-user's network, regardless of the type of the network and without looking for specific issues. This knowledge may be a valuable asset of an Internet Service Provider which may fix issues quicker or mitigate end-users' dissatisfaction.

Abstract

A method, apparatus and system for estimating reflectance parameters and a position of the light source(s) of specular reflections of a scene include RGB sequence analysis with measured geometry in order to estimate specular reflectance parameters of an observed 3D scene. Embodiments include pixel-based image registration from which profiles of 3D scene points image intensities over the sequence are estimated. A profile is attached to a 3D point and to the set of pixels that display its intensity in the registered sequence. Subsequently, distinction is made between variable profiles that reveal specular effects and constant profiles that show diffuse reflections only. Then, for each variable profile diffuse reflectance is estimated and subtracted from the intensity profile to deduce the specular profile and the specular parameters are estimated for each observed 3D point. Then, the location of at least one light source responsible for the specular effects is estimated. Optionally, the parameters can be iteratively refined to determine color information and specular reflectance parameters.

Abstract

A method and an apparatus for improving a main image by fusing the richer information contained in a secondary image are described. A 3D structure of objects contained in the secondary image is retrieved and a parallax-corrected version of the secondary image is generated using the 3D structure. For this purpose a camera pose for which a projection of the 3D structure of the objects contained in the secondary image best resembles the perspective in the main image is determined and the parallax-corrected version of the secondary image is synthesized based on the determined camera pose. The parallax-corrected version of the secondary image is then fused with the main image.

Abstract

A method and an apparatus for matching corresponding frames in two multimedia streams are suggested. The first multimedia stream is an original multimedia stream for which meta-data are available. The second multimedia stream is broadcasted or multi-casted multimedia stream and has undergone processing steps such that the meta-data of the original video stream are no more available or no longer reliable. The matching of corresponding frames in the two multimedia streams is based on the comparison of audio fingerprints and the detection of shot boundaries. Matching corresponding frames with frame accuracy enables inserting targeted content like advertisements into a sequence of video frames especially in a broadcast or multicast environment where meta-data and time markers cannot be relied upon.

Abstract

The invention relates to the improvement of the resolution of regularly sampled multi-dimensional signals, where a single low-resolution signal is available. These methods are generically referred to as example-based super-resolution or single-image super-resolution. The method for super-resolving a single image comprises three stages. First, an interpolation-based up-scaling of the input image is performed, followed by an equivalent low-pass filtering operation on the low-resolution image. The second stage comprises a search for low-frequency matches between an inspected patch in the high-resolution image and patches in a local neighborhood in the low-resolution low-frequency image, including partly overlapping patches, and accumulating the high-frequency contribution obtained from the low-resolution image. The third stage comprises adding the contributions of the low-frequency band of the high-resolution image and the extrapolated high-frequency band.

Abstract

With quantization index modulation QIM it is possible to achieve a very high data rate, and the capacity of the watermark transmission is mostly independent of the characteristics of the original audio signal, but the audio quality suffers from degradation with each watermark embedding-and-removal step. In order to avoid degradation of the audio quality, the inventive audio signal watermarking uses specific quantizer curves in time domain and in particular in frequency domain for embedding the watermark message into the audio signal, whereby the processing is almost perfectly reversible. Furthermore, it has embedded a power constraint in order to guarantee that the modifications of the audio signal due to the watermark embedding are inaudible.

Abstract

The invention relates to an improved robustness in upscaling the resolution of regularly sampled multi-dimensional signals, where a single low-resolution signal is available. These methods are referred to as example-based super-resolution or single-image super-resolution. A method for super-resolving a single image comprises three stages. First, an interpolation-based up-scaling of the input image is performed, followed by a Local De-noising step in contour regions. The second stage comprises extrapolation through cross-scale block matching, wherein an extrapolated high-frequency band is obtained that is de-noised through regularization in the same contour regions. The third stage comprises adding the contributions of the low-frequency band of the high-resolution image and the extrapolated high-frequency band.

Abstract

A parameter detector sends at least one test signal to a display and receives at least one detected display parameter from a remote control device in proximity of the display. A content parameter analyzer retrieves at least one content parameter from content to be sent to the display. A parameter comparator then compares the detected display parameter to the content parameter and adjusts outgoing content signals based on the content parameter but in accordance with the detected display parameter. The parameter comparator provides at least one suggested display parameter adjustment when the content parameter is beyond the detected display parameter. The suggested display parameter can be transmitted using a video and/or an audio signal.
