ABSTRACT:
An image analysis system is described in which the video signal information is processed so that only the measurements on any one feature are delivered to the output during any one frame scan.
In a modification, the function of the computing circuit performing the measurements on the signals arising from scanning the features is changed from frame scan to frame scan until a complete programme of different parameter measurements has been performed on the signals relating to one feature (one parameter being dealt with during each frame scan). The analysis is then transferred to the next feature in the field as outlined above and the same programme of measurements is carried out on the next feature.
In a further modification a portion of the video signal containing signals relating to the end of a feature is stored for a number of frame scan periods and is substituted for the corresponding portion arising during the subsequent frame scans, so that the position of the end of the selected feature is fixed whilst the different parameter measurements are made thereon.
