Abstract
A circuit for filtering isolated errors from an input binary signal m is used to filter noise from binary motion classification signals in a DATV video signal processing environment A first AND gate whose inputs are connected to the input on either side of delay delta Pa detects autocorrelation in the signal m; OR gate connected to the output m' of the AND gate reproduces the input sequence of binary signals with isolated 1s or 0s removed. The provision of further AND gates and an OR gate allows the reproduction of the noise reduced input binary signal with the use of automatic enable signal AUT. <IMAGE>
Description
rre:s IMPULSE RcPONSL, ON S FILTER.
'MIRF' 'HDTV/digital video'
The mean impulse response filter as a majority flag number logic filter provides a 'mean' procedure auto-correlation and corrective substitution of 'solo' vision information by blocking single occurrence errors in intrafield pixel representations as remedy for random code and process hazards found of matrix, frame or field scan-lines of vision, video, and television, including HDTV data-rate reduction for a (k'n) suppression frame or video compression m-descriptor.
The mean impulse response filter, for a majority flag logic-filter, can additionally be used to advantage in the monomode location of the intrafield flag q signal of the finite temporal-domain impulse response filter at the
ADLT-transform output of the absolute difference calculator.
The 'mean' filter remedy or auto-correlation and logic delay correction only responds with a logic 't' positively when two or more directly consecutive or adjacent logic '1' intrafield flags or b(m) singleton functions !Pkn,x,y)2, and therefore discriminately ignores or blocks the odd solo entry of singular logic '1' binary representatives in singularity equal to one intrafield flag or singleton !Pkn,x,y) while admitting both odd and even multiples of two or more intrafield pixels of !Pkn).The pixelisation representations as intrafield flag logic, or b(m) singletons, and the (DATV/DIRF) channel m-descriptor are motion classified to the frame point composition of flag data by the finite temporal-domain impulse response filter of GB 2 265 783 (n) here illustrated by Figures 1 to 4, et al. The 'mean' procedure with a picture data substitution b(n) method is for an added intermediatary filter to the (P,x,y) resolution of the FT-DIR filter and (DflTV) channel.
The 'mean' estimated rectification determinant from intrafield picture data provided in the flag number logic filter is suitable for remedying the compression.codification hazard error of HDTV/DATV, digital television or video, and vision system processes. The multiple pixel representation of
Y, U/v, monochrome, IR or B & intrafield picture data or signals by a phased bit rate reduction to flag logic or singletons, precede the mean impulse response filter (MIRF) as given and illustrated by Figure 5 to 8.
The set of drawings and illustrations are here given only by way an embodiment example as follows:
Figure 1. Diagrammatic illustration of the binary visual network of the kinematic temporal lattice shows the change states for motion detection arising in the primary 'cache' AT memory delay. The four motion class vectors of quantum 1, + t/2, - 1/2, and 0 from the central (kn) frame are analytically reduced, as shown from across the 'doublet ' temporal transfer or or hamiltonian (h) dilation delay, to 'one-bit' Pkn-1/Pkn+1 representatives of q, p, b(m), etc.

In an arithmetic mean operation the first or spatial period
Of the interpixel binary memory (SPa) delay of the boolean correlation is by scan-line sampling the reduced sequence pair provided between any spatially adjacent logic representations of P1 to P2, P2 to P3, etc, being intrafield representations q, or p, or b(m) code of Figure 1 to 4, when taken into the 2-input boolean AND-gate function. This implies the initial binary signal code loss of the first representative pixel element (3!Pkn,x,y) of any segmentation group, or serial multiple of intrafield flags or singletons, from the vision or video signal.This interim loss of a single pixel representation is prior to the boolean operation of the correlation AND-gate when a second, or higher order, consecutive adjacent logic 'I', as a pixel representation, or singleton, which auto-correlates in the AND-gate with the earlier intrafield flag '1' logic sample (or singleton). The initial pixel representation simultaneously enters the 2nd input of the boolean NND-gate after the time-recursive (SPa pAND-gate) memory period and thus generates the intrafield signal flag of an interim q', p', m' for the first stage output. The boolean auto-correlation AND-gate logic is shown of Figure 5 & 7, and the operation of both the RND & OR boolean gate stages together in sequence is shown separately in both Figures 5 & 6. The graphical presentation of the signal network of Figures 7 & 8 is into the form of a Mealy and Moore type diagram through which a vision scanning cycle of intrafield representatives or singleton flags is driven to result in the b(n) output. The boolean recursive auto-correlation by the AND-gate function feeds the second recursive memory (bob) delay of an interpixel period duration to provide an auto-corrective substitution of a dual identity by the OR-gate selection function.
The interpixel spatial (pea) interval value of an image scan-line, when circuit modelled by a binary (pea) memory delay, for intrafield flags or singletons, provides for the 2-input boolean auto-correlation of the AND-gate memory integration of Figures 5 & 7 in recurrence. This is the core boolean recursive memory and auto-correlating AND-gate function for a recurrence identifier which is the essential primitive stage for any monomode type filter to function as of
GB 2 274 371 (n) and GB 2 265 783 (n). The flag filter auto-correlation responds to higher power order value functions of !Pkn, x, y) only, as ss!Pkn, x, y)2 and above, see Figures 5 to 7.
System-filter interface timing.
The time-domain auto-correlation function between two franchise representations (say P1 and P2, or P2 and P3, etc) needs the later substitutional recycling correction of the second stage boolean OR-gate selector function of Figures 6 to 8. The recurrent substitution enabled of the initial first discriminated intrafield flag or singleton lost at the boolean AND-gate function allows the number of data entities quantised in the segmentation or binary group to remain constant for function lengths of Pn > = 2. The timing set-back of the spatial delay (SPa) is overcome by a one-pixel early start to the frame commencement of scan-line synchronisation after the fly-back period.
The spatial first memory AND-gate auto-correlation function across the virtual image delay (6Pa) period looses a single flag or singleton representation which is later overcome in a later sequence with the estimation substituted of the motion vector provided by the second binary memory (6Pb) delay holding the substitutional data identity ('m') as the reserve logic signal. The flag selector operation is by the boolean 2-input OR-gate function for any motion vector CbIitoil7 + b(m), singleton, or intrafield flag, as previously described.
The automatic permutation of the previous flag ('m') pixel, after the interpixel period (6Pb) memory delay is the reserve logic value ('m') as remaining from within the time-domain interval of ( & a and sPb) extending from Pi, P2 up to P3 of the (3x3) scan-line neighbourhood.
The mean impulse response filter method for intrafield flags or singletons is applicable for coding derived from (HDTV)
Bandwidth reduction employing a DATV channel GB 2 265 783 CA) in Figure 9 of bandwidth or datarate reduction, GB 2 265 784 (n) and GB 2 266 638 (A) of VIMCND, and GB 2 274 371 (A).
The self-enumerating mean impulse response filter can be used in flag number logic-filter locations situated within synchronisation adjustment on either or both sides of the DATV channel data codec. Thus any DATV channel codec can convey at chance the transitive permutation or selection dual of either the (x,y,m') OR (x,y,'m') window value for a (bn) flag feeding the quantum + 1/2 forward-data or other intrafield flag.
The logic-filter locations are accommodated wherever the frame image has leading estimated-compensation allowed in the adjustment of timing co-ordinates for the intrafield picture data with precise image locations for colour-cell automata during the video/control matrix scan-line. The early edge-start of each scan-line of the suppression frame is therefore phase-advanced for the reconstruction frame during the fly-back compensation timing by minus one interpixel interval (-8Pa) with respect to the system frames, and the later reconstitution frame for the final field synchronisation.The pre-enable is of the latter m transitive entering the boolean 2-input AND-gate, simultaneously with mode 'm from the spatial memory (SPa). The mean 'm flag representation is from previous pixel slot P2, and is mutually applied to the integral boolean correlation of the AND-gate function against the third P3 pixel flag representation m entry of the m-descriptor, b(n) or b(n), or singleton. n covering'conjugate subpixel enters substitute memory (SPb).
The complete binary system of the mean impulse response filter of Figures 5 to 8 can provide a further intrafield flag b(n) for the channel scheme option in duality with either (x,y,m') OR (x,y, 'm') from the penultimate boolean OR-gate output of the 'mean' substitute logic. This has the advantage of the virtual value replacement by b(n) of any correlation erial which has been spatially scan-line proven of the set CbIltoll3, as run-length-code signals of (m) transitives for motion analytic and reduced-bandwidth signal transmission.
Kinematically the singleton, m-descriptor or b(n) data-predictor in absolute arises from between pixel frames (kn-1) or (kn+1) and (kn) onto the (k'n) suppression frame data for the digital P3 up-conversion algorithm processes and final screen display. The display field allocation of fully-motive motion class 1/quantum 1, frame-rate (Hz) up-conversion for colour-cell automata on the display screen is achieved with the source code P3 picture up--conversion algorithm of the Destination System receiver-set with intrafield b(1) and b(3) synthesis in the field.
The general boolean logic-filter equation for the picture data window b(n)/b(n) resultant of the intrafield flags or m-descriptor, with reserve pixel 'm' substitution by parenthesis (memory) of Figures 7 & 8 for the mean impulse response filter is as follows,
as recurrent over the sampled flag pixel addresses P1, P2 and
P3 of the applied franchise or neighbourhood. The fiND-gate logic '1' auto-correlation from two intrafield pixel samples initially provides a (bun) window output without the availability of a substitute intrafield 'm' representation.
The mean impulse response filter gives a b(n) window output from the penultimate OR-gate selection function as the (x,y,m') value after one interpixel memory period (SPa) delay, or as and when necessary of a (x,y, 'm') representation after a double interpixel period (Pa.8Pb, or 2.SPa) delay for a b(n) output flag. The additional digital-image-frame filtering adds an effective precision to the principal identifier stage for the rear-edge of motion class 2 vectors for image run-length-codifications; particularly where picture transfer noise has been incurred.
The fundamental mean impulse response filter system extends into the basis embodiment of UK Patent Applications GB 2 265 783 (R), GB 265 784 (s9), GB 2 266 638 (fl) and GB 2 274 371 (n).
The interpixel memory interval (6Pa) delay is a spatial constant parameter of time for the television, video or vision system standard of Figure 7. The second or hamiltonian constant parameter of the intrafield is the 'doublet' transfer delay transfer (sot.) time of Figure 1 ; with ratio rule option for a system standard of 6Pa / St.
The mean impulse response filter of Figures 5 to 8 is a spatial adjacency logic and physically isomorphic scan-line signalling method property for open embodiement within digital electronic systems.
