Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
An image processing system comprising means for the acquisition of video signals corresponding to a plurality of images, and means for processing these acquired signals, wherein said processing means comprise: (a) a movement estimation stage; (b) a morphological filtration stage; (c) a storage and/or visual display stage; said morphological filtration stage itself including a circuit for the definition of a space-time structuring element from movement parameters estimated by the movement estimation stage, and a morphological filtration circuit.
Claim 2
Dependent Claim
77 words
An image processing system comprising means for the acquisition of video signals corresponding to a plurality of images, and means for processing these acquired signals, wherein said processing means comprise: (a) a movement estimation stage; (b) a morphological filtration stage; (c) a storage and/or visual display stage; said morphological filtration stage itself including a circuit for the definition of a space-time structuring element from movement parameters estimated by the movement estimation stage, and a morphological filtration circuit.
Claim 3
Dependent Claim
24 words
The system according to claim 1, the movement estimation stage is preceded by a circuit for the conversion of interlaced format into sequential format.
Claim 4
Dependent Claim
33 words
The system according to claim 1 wherein, the movement estimation stage is preceded by an image readjustment circuit, a circuit determining differences between images, and a threshold circuit, all three connected in series.
Claim 5
Dependent Claim
33 words
The system according to claim 2 wherein, the movement estimation stage is preceded by an image readjustment circuit, a circuit determining differences between images, and a threshold circuit, all three connected in series.
