A power-scalable hybrid technique to reduce blocking and ringing artifacts in low bit-rate block-based video coding is employed in connection with a modified decoder structure. Fast inverse motion compensation is applied directly in the compressed domain, so that the transform (e.g., DCT) coefficients of the current frame can be reconstructed from those of the previous frame. The spatial characteristics of each block is calculated from the DCT coefficients, and each block is classified as either low-activity or high-activity. For each low-activity block, its DC coefficient value and the DC coefficient values of the surrounding eight neighbor blocks are exploited to predict low frequency AC coefficients which reflect the original coefficients before quantization in the encoding stage. The predicted AC coefficients are inserted into the low activity blocks where blocking artifacts are most noticeable. Subject to available resources, this may be followed by spatial domain post-processing, in which two kinds of low-pass filters are adaptively applied, on a block-by-block basis, according to the classification of the particular block. Strong low-pass filtering is applied in low-activity blocks where the blocking artifacts are most noticeable, whereas weak low-pass filtering is applied in high-activity blocks where ringing noise as well as blocking artifacts may exist. In low activity blocks, the blocking artifacts are reduced by one dimensional horizontal and vertical low-pass filters which are selectively applied in either the horizontal and / or vertical direction depending on the locations and absolute values of the predicted AC coefficients. In high activity blocks, de-blocking and de-ringing is conducted by 2- or 3-tap filters, applied horizontally and / or vertically, which makes the architecture simple.

The invention relates to a method for detection and prediction of incidents and traffic queues formed by overloading. This is done in real time with use of sensors in a road network. Predictions are used also to reach a faster and more reliable detection. Sensor measurements are also used in the process, where the comparison with expected values are used for successively updating stored parameter values for the involved algorithms. By this, the system can succeedingly adapt itself for changed situations. The strong traffic variations, that are naturally occurring at short time intervals are treated with the use of noise-based methods. By this, there are formed distribution related measures as e.g. the standard deviation, which can be estimated from measurements, and submit a base for estimating probabilities for deviations of a certain size, e.g. related to the standard deviation. Automatic incident detection (AID) is based on determination of the desired false-alarm rate, and the related threshold level. The method includes accumulated measurements. Faster and more reliable incident detections are received with the use of the invented prediction process method.

Superantibodies having enhanced autophilic, catalytic, and / or membrane-penetrating properties are prepared by affinity-based conjugation of a photoactivatable organic molecule to a target immunoglobulin. The photoactivatable organic molecule bears a chromophoric aromatic hydrocarbon moiety, which has affinity for the immunoglobulin. Upon photolysis, the organic molecule is covalently linked to the immunoglobulin. A preferred organic molecule is a peptide and a preferred aromatic hydrocarbon moiety is a tryptophan residue. The photoactivatable organic molecule need not bear a purine, pyrimidine or azido group to effect binding to the immunoglobulin and / or photoactivation. The superantibodies can enhance the potency and expand the targeting range of target antibodies. Autophilic superantibodies can promote apoptosis of target cells and / or enhance therapeutic efficacies in the treatment of patients with diseases or disorders responsive to antibody therapy. Exemplary of such diseases are atherosclerosis and cardiovascular disease. Membrane-penetrating superantibodies can prevent apoptosis by binding to intracellular anti-caspase signal proteins. Compositions containing the superantibodies, as well as methods of making and using them, are disclosed.
