摘要： A method for secure transmission of a data message locks, at the sender, the data message using a first lock. The locked data message is transmitted to the receiver. Next, the locked data message is double-locked, at the receiver, using a second lock. Then, this double-locked data message is transmitted back to the sender. The first lock of the double-locked data message is then unlocked, at the sender, using a first key, leaving the data message single-locked by the second lock. The single-locked data message is transmitted back to the receiver, where the second lock of the single-locked data message is unlocked, using a second key, to generate the data message, completing the secure transmission.

摘要： A system and method for encoding a two dimensional array of data utilizes a library having entries corresponding to a set of predefined two dimensional adaptive spline wavelet waveforms. Each predefined two dimensional adaptive spline wavelet waveform is formed by the superposition of one or more B-splines. The data encoding method identifies a set of best matches between the array of data and the predefined two dimensional adaptive spline wavelet waveforms by generating the inner product of the array of data and each of the predefined two dimensional adaptive spline wavelet waveforms. Each inner product is generated by FIR filtering the data with a corresponding set of FIR filter coefficients, and then determining which of the inner products have largest values. Once a set of best matches has been found, the data encoding method generates data representing the identified set of best matches. The generated data indicates for each match: one of the library entries, a position within the array of data at which the match was found, and a magnitude of the match. The data encoding method is computationally efficient because inner products are computed by FIR filtering.

摘要： A pixel filling system or method begins with an initial set of image data that is a subset of data values in a data array fk,l representing data values at corresponding positions (k,l). Some of the fk,l values are initially undefined, while others, at positions where both k and l are even numbers, have initially defined values. An interpolated value is generated for initially undefined fk,l values in accordance with the pixel filling filter equation: f k , l = ∑ i , j ⁢ P k - 2 ⁢ ni , l - 2 ⁢ nj ⁢ d i , j wherein n is a positive integer, di,j are the subset of fk,l values which have defined values prior to the generation of the interpolated fk,l values; Pk,l are coefficients, no more than sixteen of which have non-zero values; and each non-zero Pk,l coefficient is an integer divided by an integer power of two. The pixel values generated in accordance with the pixel filling filter equation represent a surface that is smooth, has continuous two-dimensional spatial first derivative, and preserves sharp edges, if any, in the initial set of image data. Further, if a local set of the initial data points di,j (e.g., neighboring ones of the fk/2,l/2 or fk/4,l/4 points) all fall on a polynomial surface, the interpolated fk,l values that are located between the initial data points also fall on that same polynomial surface.

摘要： A unified system and method for encoding an array of data. If the data array is comprised of DCT data, then coefficients from corresponding positions in the data array are mapped into a common blocks in a second data array so as to group similarly valued coefficients. If the data array is comprised of wavelet data and the wavelet tile is greater than a predetermined size, then the wavelet tile coefficients are mapped into a second array so as to combine coefficients from the same wavelet family. After the DCT or wavelet coefficients have been mapped, the DC coefficients are encoded using a differential pulse code modulation (DPCM) process. The maximum number of bits required to represent any coefficient in each block family in the data array is determined. The difference between the maximum number of bits required to represent any coefficient in the entire data array and each of the block family maximums is determined and encoded. Each block family is then successively divided into an upper leftmost block and a sub-family, and difference values between maximum numbers of component block groupings are determined and encoded. This process is then repeated until the selected sub-family comprises a single block. Whenever a sub-family is processed, if the sub-family is entirely filled with zero data it is so identified in the output data and no further processing of the sub-family is required. After all of the sub-families have been processed, the blocks are bit mask coded. After all the coefficients in a block have been processed, the bit mask is encoded. When blocks of a predetermined size are encountered, the method outputs the value of the coefficients in the block. A data decoder and method retraces the encoded data so as to reverse the process performed by the encoding method.

摘要： A data encoder and method utilizes a node list for storing a list of nodes in the data array to be processed, a branch list for storing a list of tree branches in the data array to be processed and a set list for storing a list of data sets. The method begins by initially storing in the node list node identifiers representing a predefined set of nodes in the data array, corresponding to coefficients generated by a last iteration of a data decomposition procedure. Also, it initially stores in the branch list branch identifiers representing tree branches corresponding to a predefined subset of the nodes initially listed in the node list. Each such tree branch has an associated root node and a branch depth value indicating how many node layers intervene between the root node and the nodes of the tree branch closest to the root node. The set list is initially empty, and a parameter called the LayerLimit value is also initialized. For successively smaller values of m, where m is a positive integer, a set of data encoding steps are repeatedly performed so as to process all nodes, branches and sets in the lists. A magnitude flag is output for each node, branch and set to indicate whether or not it is or contains a node whose absolute value is equal to or larger than 2.sup.m-1, and for each node, branch and set that is equal to or larger than 2.sup.m-1 further processing is performed.

摘要： A data encoding system and method successively generates compressed data on a bit plane by bit plane basis, starting with the bit position of the most significant non-zero bit for the node in the data array having the largest absolute value, and then encoding the data in the array for progressively less significant bits. All the nodes in the data array are represented initially by blocks of nodes on a block list, and later in the processing by nodes on two node lists. Whenever a block contains a node whose most significant bit is on the bit plane currently being processed, the block will be subdivided recursively until all the nodes in the block whose most significant bit in on the current bit plane are placed in a node list. Data bits representing an m.sup.th least significant bit of the block and node values are written to the compressed data file first, where m is the minimum number of bits required to represent the node having the largest absolute value in the entire data array being encoded. Data bits for successively less significant bit planes are written to the compressed data file until a bit plane stop point is reached. The bit plane stop point may be predefined, user selected, or procedurally selected (e.g., in accordance with available bandwidth for transmitting compressed image data).

摘要： A processor (10) is disclosed which uses a B-spline interpolator (14) to produce a plurality of zero-level spline coefficients c.sup.0 (n). This set of coefficients may be fed to a B-spline generator (16) to produce an approximation of the input signal, and/or may be multiplied by a set of coefficients Bn to produce a set of first-level wavelet coefficients d.sup.-1 (n). The zero-level spline coefficients are also used to create first-level spline coefficients c.sup.-1 (n). The first-level spline and wavelet coefficient c.sup.-1 (n) and d.sup.-1 (n) may be submitted to a respective B-spline generator (22) or B-wavelet generator (24) to produce a first-level spline signal components and a first-level wavelet signal component for extraction of data from the original signal. The signal may in a similar fashion be decomposed to any level of resolution desired. The signal components may then be processed, and an improved signal then reassembled from the last-level spline and the processed wavelet signals. Novel spline and wavelet generators are also disclosed.
