Abstract: 1330133 Image analysis IMAGE ANALYSING COMPUTERS Ltd 23 Nov 1970 14301/73 Divided out of 1330132 Headings G4D and G4H In a video scanning system for counting and sizing particles an electronic blanking mask is put over the border of the field being investigated and computed parameters of those particles which insect the edge of the mask are inhibited. The output of a video source such as a t.v. camera 10 is converted to constant amplitude pulses at 12. If none of these pulses is present when a blanking pulse from 16 ceases then a gate 28 is opened immediately to pass the computed parameter but if one of the constant amplitude pulses is present a NOR gate 54 prevents a bi-stable 56 being reset until the constant amplitude pulse ceases and the opening of gate 28 is delayed. This effectively generates a live frame 42 whithin the blank frame 40 which excludes all chords which intersect the frame 40. In a modification (Fig. 3, not shown) an anticoincidence detector is employed to issue a parameter release pulse after the last chord of each particle and the release pulse is inhibited for all particles intersecting the frame so that the live frame effectively excludes the whole particle (Fig. 4).
