Algorithms are developed for a real-time, automatic system capable of tracking two-dimensional (2-D) targets in complex scenes. A mathematical model of 2-D image spatial and temporal evolution applicable to certain classes of targets and target perturbations is developed. It is shown that for small target perturbations the 2-D tracking problem may be approximated as a 1-D time-varying parameter estimation problem. A CCD-implementable solution is developed which is particularly useful when considering target rotation and dilation and target/background separation. Results of system simulation and suggestions for future research are presented.

A Model and Tracking Algorithm for a Class of Video Targets

An optical system has an optical image projected on an analog memory, such as a CCD array, generating analog charge signals in the analog memory. The analog charge signals are processed with an analog to digital converter to generate digital information. The digital information is processed with an integrated circuit frequency domain processor to generate frequency domain information. The frequency domain information can be stored in an output memory and can be communicated to a remote location. An image can be displayed in response to the stored analog image information and in response to the frequency domain information. A machine can be controlled in response to the frequency domain information.

The development of algorithms for real-time, automatic systems capable of tracking 2-D targets in complex scenes is discussed. The problems and constraints involved in such an undertaking as well as previous efforts are summarized. in addition, a mathematical model of scene spatial and temporal evolution is developed for certain classes of targets and target perturbations. It is shown that for small target perturbations the 2-D tracking problem may be approximated as a 1-D time-varying parameter estimation problem. Algorithms resulting from several estimation approaches are discussed.

Algorithm development for real-time automatic video tracking systems

The present invention is directed to a read only memory, wherein the preferred embodiment provides an analog read only memory using charge coupled devices. Fixed but selectable charge packets are used to charge elements in a charge coupled device array; where selectable charging may be provided by selecting resistor values, selecting capacitor values, selectable masking of photo detectors, and other such methods. The accumulated fixed packets of charge are then shifted with a charge coupled device register to provide sequential analog signal outputs. Use of an analog read only memory permits hybrid signal processing such as for voice response. Use of a serial output simplifies the accessing and reduces accessing electronics by eliminating the more complex random access arrangements. The analog read only memory of the present invention has the additional advantage of being a non-volatile memory for preserving stored information when power is removed; where conventional charge coupled device memories are volatile and lose all stored information when power is removed. The analog read only memory of the present invention is particularly useful in systems for generating analog output signals such as voice response systems and filtering systems. Accessing of analog samples from the read only memory can be controlled with a digital processor such as by controlling shifting of the charge couple device shift register and by selecting the desired output information under digital control.

Analog read only memory

The use of charge-coupled devices (CCD's) for pattern recognition applications is discussed. In particular, it is suggested that the new CCD technology may satisfy the large memory, fast processing speed, low cost, small size, and low power requirements which could make practical many pattern processing systems which until now have not been feasible. Specific implementations are suggested along with estimates of processing times.
