Device for the detection of objects in a sequence of images
First Claim
Patent Images
1. A device for detection of one or more objects in a sequence of images, said sequences of images including objects of varying magnitude, comprising:
- (a) means for forming a current registered image and a prior registered image from the sequence of images;
(b) means for increasing an absolute contrast of smaller objects with respect to an absolute contrast of larger objects within the current registered image and for producing a first output,(c) means, operating in parallel with said means for increasing an absolute contrast, for increasing a contrast of moving objects between said current and said prior registered images producing a second output; and
(d) means for receiving said first output of said means for increasing an absolute contrast and said second output of said means for increasing a contrast of moving objects between said current and said prior registered images for making a final selection of signals considered as corresponding to the objects to be detected.

Abstract
A device for the detection of objects in a sequence of images. The device having a means for registering images, means for increasing the contrast of objects within a registered image, means for increasing the contrast of moving objects between two registered images and means for a final selection of signals considered as corresponding to the objects to be detected.
