When making digital data recordings using some form of computer or calculator, data is input in a variety of ways and stored on some form of electronic medium. During this process calculations and transformations are performed on the data to optimize it for storage. This invention involves designing the calculations in such a way that they include what is needed for each of many different processes, such as data compression, activity detection and object recognition. As the incoming data is subjected to these calculations and stored, information about each of the processes is extracted at the same time. Calculations for the different processes can be executed either serially on a single processor, or in parallel on multiple distributed processors. We refer to the extraction process as “synoptic decomposition”, and to the extracted information as “synoptic data”. The term “synoptic data” does not normally include the main body of original data. The synoptic data is created without any prior bias to specific interrogations that may be made, so it is unnecessary to input search criteria prior to making the recording. Nor does it depend upon the nature of the algorithms / calculations used to make the synoptic decomposition. The resulting data, comprising the (processed) original data together with the (processed) synoptic data, is then stored in a relational database. Alternatively, synoptic data of a simple form can be stored as part of the main data. After the recording is made, the synoptic data can be analyzed without the need to examine the main body of data. This analysis can be done very quickly because the bulk of the necessary calculations have already been done at the time of the original recording. Analyzing the synoptic data provides markers that can be used to access the relevant data from the main data recording if required. The nett effect of doing an analysis in this way is that a large amount of recorded digital data, that might take days or weeks to analyze by conventional means, can be analyzed in seconds or minutes. This invention also relates to a process for generating continuous parameterised families of wavelets. Many of the wavelets can be expressed exactly within 8-bit or 16-bit representations. This invention also relates to processes for using adaptive wavelets to extract information that is robust to variations in ambient conditions, and for performing data compression using locally adaptive quantisation and thresholding schemes, and for performing post recording analysis.

A method is provided for training a statistical pattern recognition decoder on new data while preserving its accuracy of old, previously learned data. Previously learned data are represented as constrained equations that define a constrained domain (T) in a space of statistical parameters (K) of the decoder. Some part of a previously learned data is represented as a feasible point on the constrained domain. A training procedure is reformulated as optimization of objective functions over the constrained domain. Finally, the constrained optimization functions are solved. This training method ensures that previously learned data is preserved during iterative training steps. While an exemplary speech recognition decoder is discussed, the inventive method is also suited to other pattern recognition problems such as, for example, handwriting recognition, image recognition, machine translation, or natural language processing.

A radar on a moving platform generates an initial synthetic aperture (SAR) image of a scene from a sequence of periodic pulse returns approximately motion compensated. The SAR image is formed from pixel intensities zn(x,y) within a x,y extent of the initial synthetic aperture image. Targets are selected from the initial synthetic aperture image using a sliding window, computing a first entropy for the selected targets, and sorting the targets using the first entropy to obtain a target list having target elements, then concatenating the target elements to form a data matrix compatible in the azimuth dimension with a Fast Fourier Transform.A phase correction for autofocus is iteratively computed and applied to the initial synthetic aperture image using an inner loop, a mid loop and an outer loop. The phase correction is expressed using an orthogonal polynomial having a plurality n consecutive terms an, a2 denoting a quadratic term, and aN denoting a last order term. The outer loop, using an L index, calculates an outer loop EL(a2) entropy for the quadratic term and an outer loop EL(aN) entropy for the last order term. Iterations within the outer loop continue until EL(a2)−EL(aN) is less than an outer loop tolerance.Similarly, the mid loop, and inner loop continue until the computation of their respective entropies meet a pre-set tolerance. The inner loop entropy uses a Golden Section search for computing the inner loop entropy.
