Patent number: 10205958Abstract: A more efficient co-use of dynamic range mapping on the one hand and temporal prediction on the other hand such as, for example, in order to code HDR frame sequences, is achieved by exploiting the concept of weighted prediction in order to transition from the mapping parameter from the reference frame to the currently temporally predicted frame. By this measure, the temporal prediction does not fail and despite the frame-wise variation in the dynamic range mapping, encoding efficiency is, thus, maintained. As a favorable side aspect, weighted temporal prediction is already within the capabilities of existing video coding stages such as, for example, the H.264/AVC.Type: GrantFiled: November 16, 2016Date of Patent: February 12, 2019Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Jens-Uwe Garbas, Herbert Thoma

Publication number: 20190045206Abstract: A coding efficiency improvement is achieved by performing bit-plane coding in a manner so that coefficient groups for which the set of coded bit-planes is predictively signaled in the datastream, are grouped in two group sets and if a signal is spent in the datastream which signals, for a group set, whether the set of coded bit-planes of all coefficient groups of the respective group set are empty, i.e. all coefficients within the respective group sets are insignificant. In accordance with another aspect, a coding efficiency improvement is achieved by providing bit-plane coding with group-set-wise insignificant signalization according to the first aspect as a coding option alternative relative to the signalization for group sets for which it is signaled that there is no coded prediction residual for the coded bit-planes for the claim groups within the respective group set.Type: ApplicationFiled: July 10, 2018Publication date: February 7, 2019Inventors: Joachim KEINERT, Thomas RICHTER, Miguel Ángel MARTÍNEZ DEL AMOR, Manuel DE FRUTOS LÓPEZ, Christian SCHERL, Herbert THOMA, Siegfried FOESSEL

Publication number: 20190014321Abstract: Embodiments of the invention concern coders, e.g. a decoder for decoding a sequence of portions of media from a data stream. The decoder is configured to decode, for a current portion, a signed integer variable from the data stream by use of a unary code comprising a series of codewords of increasing length which are sequentially assigned to possible values of the signed integer variable in a manner so that a first possible value having a first sign and a predetermined absolute value has assigned a first codeword of the unary code of a first length which differs from a second length of a second codeword of the unary code assigned to a second possible value having a second sign and the predetermined absolute value, or being zero with the predetermined absolute value being one, by exactly one.Type: ApplicationFiled: July 7, 2017Publication date: January 10, 2019Inventors: Joachim KEINERT, Thomas RICHTER, Herbert THOMA, Christian SCHERL, Manuel DE FRUTOS LÓPEZ, Siegfried FOESSEL, Miguel Angel MARTINEZ DEL AMOR

Patent number: 9916645Abstract: A chroma subsampling having reduced artifacts is achieved by detecting high contrast areas in a luminance channel of an image to be chroma subsampled so as to partition the image into a first region composed of the high contrast areas and a second region distinct from the first region, with chroma subsampling the image in the first region using a first chroma subsampler and chroma subsampling the image in the second region using a second chroma subsampler, with the first chroma subsampler having a higher edge preserving property than compared to the second chroma subsampler. Thereby, bleeding artifacts may be avoided at least partially, while the saturation of the image may be substantially preserved.Type: GrantFiled: November 13, 2015Date of Patent: March 13, 2018Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Herbert Thoma, Christian Scherl

Publication number: 20170366830Abstract: Audio video synchronization and alignment or alignment of audio to some other external clock are rendered more effective or easier by treating fragment grid and frame grid as independent values, but, nevertheless, for each fragment the frame grid is aligned to the respective fragment's beginning. A compression effectiveness lost may be kept low when appropriately selecting the fragment size. On the other hand, the alignment of the frame grid with respect to the fragments' beginnings allows for an easy and fragment-synchronized way of handling the fragments in connection with, for example, parallel audio video streaming, bitrate adaptive streaming or the like.Type: ApplicationFiled: September 6, 2017Publication date: December 21, 2017Inventors: Bernd CZELHAN, Harald FUCHS, Ingo HOFMANN, Herbert THOMA, Stephan SCHREINER

Patent number: 9712816Abstract: The ratio between coding quality on the one hand and coding rate on the other hand is increased. To this end, a global predictor and a local predictor are used in combination. The global predictor derives a global tone-mapping function based on a statistical analysis of pairs of values of co-located samples in the first tone-mapped version and the second version of the picture, and applies the global tone-mapping function onto the first tone-mapped version of the picture. The local predictor locally derives a locally varying tone-mapping function based on a statistical analysis of values of co-located samples in the second version of the picture and the globally predicted reference picture in units of sub-portions into which the globally predicted reference picture and the second version of the picture are partitioned, and applies the locally varying tone-mapping function onto the globally predicted reference picture.Type: GrantFiled: May 8, 2014Date of Patent: July 18, 2017Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Jens-Uwe Garbas, Herbert Thoma

Patent number: 9445102Abstract: A more accurate model parameter estimation is achieved by using a Kalman filter for discretely estimating the model parameters between the consecutive frames of the frame sequence and performing the correction of the time-discrete Kalman filter twice per frame, firstly using a measurement value which depends on a complexity measure of the current frame to achieve a primarily corrected state of the time-discrete Kalman filter, and secondly using a measurement value depending on an actual coding rate or distortion of the video encoder in encoding the current frame using a predetermined quantization which may have been determined by an estimation of the actual rate- or distortion-quantization function according to the primarily corrected state. A rate-quantization model function relates the quantization of the video encoder to the coding rate of the video encoder and is piecewise defined to exhibit quadratic and exponential functions in finer and coarser quantization intervals, respectively.Type: GrantFiled: July 5, 2012Date of Patent: September 13, 2016Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.VInventors: Manuel Schwaab, Herbert Thoma

Patent number: 8462845Abstract: A method for determining an order of values for an encoding parameter of a hybrid encoding scheme for each frame of a frame sequence for use for encoding the frame sequence by means of the hybrid encoding scheme is described. Using the hybrid encoding scheme, resulting distortions and compression rates for the frames of the frame sequence are established for the case of the complete encoding of the frame sequence, and for the case of the incomplete encoding of a real partial sequence of the frame sequence. Thereupon, establishing of estimated distortions and compression rates for frames of the frame sequence takes place, followed by determining the order of values for the encoding parameter of the hybrid encoding scheme based on the established resulting and estimated distortions and compression rates.Type: GrantFiled: August 25, 2006Date of Patent: June 11, 2013Assignee: Franhofer-Gesellschaft zur Ferderung der angewandten Forschung e.
