    摘要: Methods and apparatus are provided for efficient video encoding and decoding of intra prediction mode. An apparatus includes a video encoder for encoding picture data for at least a block in a picture by determining a spatial pattern for a decoded intra prediction mode residue used to reconstruct the picture at the video encoder. The decoded intra prediction mode residue is obtained by inverse quantizing and inverse transforming a transformed and quantized difference between an original version of the block and at least one reference block. The spatial pattern is used to determine an intra prediction mode for encoding the block.

    摘要: Methods and apparatus are provided for implicit and semi-implicit intra mode signaling for video encoders and decoders. An apparatus includes an encoder for encoding picture data for at least a portion of a picture. The encoder derives an intra mode to apply to the portion from neighboring template data and abstains from explicitly signaling the intra mode for the portion. The neighboring template data corresponds to a neighboring template formed from neighboring pixels with respect to the portion.

    摘要: The invention relates to a method of encoding an image divided into non-overlapping macroblocks themselves divided into non-overlapping blocks of N by N pixels into a binary stream. It comprises the steps of: —transforming each of the block into a transformed block of coefficients comprising one low frequency coefficient and N2-1 coefficients, called high frequency coefficients, of higher frequencies than the low frequency; —quantizing each coefficient of each of the transformed blocks with a quantizing parameter; —encoding the quantized coefficients into a binary stream. According to the invention, the low frequency coefficients of the transformed blocks are quantized with a same quantizing parameter, called first quantizing parameter.

    摘要: A spatial activity metric for characterizing an image is established, typically based one of the image variance, image gradient or DCT coefficients. The spatial activity metric is then reduced by the amount of the estimated noise in the image so that upon the spatial activity metric in connection with spatial masking, the likelihood of unmasked distortion caused by the presence of noise, such as film grain will be reduced. The effectiveness of such a spatial activity metric can be determined by determining similarity of the measures made by the spatial activity metric for regions in the image of similar texture and by determining the difference in the measures made by the spatial activity metric for regions of different texture in the image.

    摘要: The present invention provides a wireless ad hoc network suitable for sharing data on a peer-to-peer basis between nodes, some of which may be aircraft, having a terminal device comprising a wireless communications transceiver, a sensor, and a computing device. Multiple hops between nodes maximize range of the network. In addition, architectures for terminal devices allow for use of a wide variety of wireless communications transceivers and sensors, without affecting applications that use the network. Such invention may include, among others, a fire fighting application allowing different aircraft to co-ordinate firefighting activities by using shared fire and positional data for aircraft.
